Description
10657l34 This invention relates to apparatus for use in trans-porting materials such as sand into storage buildings having entrances only at ground level and for stacking the materials inside such storage buildings.
Bulk materials such as sand are sometimes transported in warmer weather to a more convenient location where the mate-rials are stored under cover for use in winter. For instance ¦~
sand is stored in light prefabricated storage buildings for !
use in winter on road surfaces. Such storage limits problems which would be caused by rain freezing in the sand.
Because the storage buildings are not very strong,it is conventional to fill them by dumping the material at ground level in an entrance to the structure and to then push the material into a stack using a suitable bulldozer or other equipment. Each load must be moved onto the stack before another load of material is dumped. Also, as the stack is increased in height it naturally becomes more difficult to push the material onto the stack.
It is an object of the present invention to provide ;
apparatus for use in receiving such materials from a truck and for transporting the materials directly onto a stack within a light storage building. ~' Accordingly, apparatus is provided consisting essen-tially of a feeder which receives materials from trucks and a stacker which receives the materials off the feeder and trans-ports the materials to a point where the materials are dropped into a stack. Provision is made for adjusting the height from which the materials are dropped and the stacker has adjustable wheel assemblies to permit the stacker to be moved transversely `,-at the wheels so that the stacker swings in a horizontal arc , :
.
:. ' . ' ,"'; ' ' .' ' ~ ' ~ ' ' ' ~065784 and the stack can be thereby increased in size with respect to - -the area covered by the stack. -The invention will be better understood with reference to the drawings, in which:

Fig. 5 is a perspective view to a larger scale than that used for Figs. 2 to 4 and illustrating a part of the stacker used to move the towing end of the stacker between ~

Fig. 3; -Fig. 6 is a perspective view to a similar scale to that used for Fig. 5 and illustrating a portion of the stacker ~ -~ J~' used to mount a wheel, the structure being in a trailing posi-tion; and Fig. 7 is a view similar to Fig. 6 and showing the wheel in position for manoeuvring the stacker inside the stor-age building shown in Fig. 1.
Reference is first made to Fig. 1 which illustrates apparatus according to a preferred embodiment of the invention : ' ~ ;! ' ' and indicated generally by the numeral 20. The apparatus con-sists of a feeder 22 which receives material from trucks and feeds the material onto a stacker for depositing the material inside a storage building 26. Such buildings are of a very light structure and commonly include internal retaining walls which in this instance have been omitted to simplify drawing.
The apparatus 20 permits material to be dumped into I -a hopper 28 on the feeder 22 and then conveyed to a receiver 30 on the stacker 24 before being elevated by the stacker in-side the building 26. Both the feeder and the stacker can be towed behind tractors and it is possible to ad~ust the posi- ~ `
tion of the stacker inside the building by adjusting the wheels on the stacker as will be described.
Reference is next made to Fig. 2 to describe the feeder 22 in more detail. The feeder 22 includes a chassis frame 32 extending longitudinally and supported by a pair of road wheels 34 and, when in use, by manually operated foot 36.
The frame 32 has a hitch 38 for towing and a rear portion of the frame is inclined upwardly from the wheels 34 to provide elevation for depositing materials off the feeder onto the stacker 24, part of which is shown in ghost outline in this ~ '!
figure.
The feeder includes a pair of ramps 40, 42 which are pivotally mounted on the chassis frame 32 for movement trans-versely so that they can be moved from a lowered position as drawn into a vertical stored position when the feeder is being towed. The ramp 40 can be seen in the stored position ~-in ghost outline in Fig. 2.
Materials are dropped into hopper 28 from a truck 1-which can be backed up the ramps 40, 42 and the hopper 28 ;: . .. . . . . .
. . ....
.' ' - '' ~65784 locates the materials and allows them to fall onto another part of a conveyor belt 44 which transports the materials longitud-inally past the wheels 34 and upwardly to an end roller 46 mounted at the end of chassis frame 32. The materials then fall downwardly beyond the roller onto the stacker 24. ,`-The conveyor belt 44 is driven from a gasoline engine and gearbox assembly 48 mounted on a platform 50 generally above wheels 34 and associated with the chassis frame 32. The -assembly 48 acts as a prime mover to drive a belt 52 which is .
in turn coupled to driven wheels associated with conveyor belt 44. Suitable supports for the conveyor belt 44 are provided such as supports 54 and 56 and tensioners 57 (one of which is .
seen) are provided at both ends of an end roller 59.
The conveyor belt 44 is driven at constant speed and `
as will be described the material which falls onto the stacker 24 can be distributed by moving the stacker while the feeder continues to move materials onto the stacker.
Reference is now made to Fig. 3 to describe the stacker 24. The stacker consists essentially of an elongated 20 boom 58 supported adjacent one end by a foot assembly 60 and `- ~
toward its opposite end by a pair of hydraulically extensible ~ -elements 62 (one of which is seen) and which are dependent from a sub-frame 64. This sub-frame extends between the foot ,~
assem,bly 60 and a cradle 66 to which is attached a pair of ~- ~
adjustable wheel assemblies 68 (one of which is seen in this - -view). Each of the wheel assemblies can be pivoted about one -of two parallel vertical axes so that the associated wheels move into positions such as that indicated in ghost outline.
The wheel assemblies will be more fully described with refer-ence to Figs. 6 and 7.
.~ . .. . .......... . . .
.
The cradle 66 includes an inclined upper support 70 on which the boom 58 can be rested when the stacker is in a rest position ready for towing as will be more fully described with reference to Fig. 4.
In Fig. 3 the stacker is in a position in which it is moving elevating material from the feeder 22 to a position for stacking the material. A prime mover 72 in the form a a gaso-line engine and gearbox is connected by a belt drive 74 to a drive system for a conveyor belt 76. The upper path of this conveyor belt extends from a first support roller 78 to an end support roller 80 so that material which drops into the re-ceiver 30 is carried by the conveyor belt to the remote end of the boom 58 and dropped over the roller 80. The elevation ;
of the roller 80 can be adjusted by utilizing the element 62 and sideways motion of the boom is possible using the wheel assemblies 68 in the ghost outline position. With the wheels in this position the boom can be moved sideways by applying a side force and the boom will then effectively rotate about the foot assembly 60. There will be minimal side motion of the 20 receiver 30 so that effectively the receiver continues to be -positioned under the end wheel 46 of the feeder 22 and material will continue to flow from the feeder 22 to the stacker 24.
Reference is next made to Fig. 4 to describe foot assembly 60 which is shown in Fig. 4 in a lowered condition which contrasts with the withdrawn condition shown in Fig. 3.
The foot assembly includes a wheel 82 on which the stacker rests when the foot assembly is in the lowered condition. A foot pad 84 is elevated above the wheel in this condition but, as seen in Fig. 3, the stacker rests on this foot pad with the foot assembly in the withdrawn condition.
: .. -.. .. .....
- ~ .' . ' , . . ..
, ' ', '" ': "'.'~' ~'" ' ' :
As best seen in Fig. 5, the foot assembly 60 is at-tached to the boom by a pair of parallel brackets 86 which ex-tend downwardly. A shaft 88 is fixed in the brackets 86 and foot pads 84 are suspended from the shaft 88.
The foot assembly 60 also includes a frame 90 which is pivotally mounted on the shaft 88 and which carries an in- Ij clined support plate 92 which provides a bearing surface for a ¦-rotatable wheel mount 94 carrying a wheel 96. ~he frame 90 also includes a trunnion 98 to which is coupled one end of a hydraulic actuator 100. The other end of this actuator is attached to a bracket 102 on a transverse member 104 of the boom.
It will be evident from Figs. 3, 4 and 5 that opera-tion of the actuator 100 will result in moving the foot assem-bly from the withdrawn position shown in Fig. 3 to the lowered position shown in Fig. 4. Similarly, the movement can be re-versed by bleeding hydraulic fluid from the cylinder 100 in a controlled fashion.
When the foot assembly is in the Fig. 4 position and the wheel assemblies 68 are in the straight-ahead or towing position, the stacker can be moved longitudinally. If it is dsired to tow the stacker, then the foot assembly 60 can be used to elevate a leading end of the stacker for positioning this end on a tow hitch of a truck or the like. The foot assem-bly is then raised to the Fig. 3 position to permit towing of the stacker with the boom in the lowered position as indicated in ghost outline in Fig. 3.
Reference is next made to Fig. 6 to describe one of the pair of adjustable wheel assemblies 68. As seen in Fig. 6, 30 the sub-frame 64 includes a heavy transverse element 106 which ~{: :
:............................ . . .. .
f ~--extends between a pair of parallel side elements 108 (one of which is seen in this view). Parts of the cradle 66 (Fig. 3) extend from the side elements 108 and rearward ends of these elements are connected to the extensible hydraulic elements 62 (Fig. 3).
A stub axle assembly llO is attached by a vertical fitted bolt 112 to a horizontal extension piece 114 which in turn is welded to one of the side elements 108. The stub axle assembly includes a reinforced U-shaped element 116 having re-spective upper and lower legs 118, 120 in sliding contact with the respective upper and lower surfaces of the extension piece 114. The U-shaped element 110 supports a stub axle 122 to which a wheel 124 (shown in ghost outline) can be attached in ;
conventional manner.
The stub axle assembly 110 is locked in position rela-tive to the extension piece 114 by a fitted pin 126 which extends - -downwardly through upper leg 118, through the extension piece 114, and finally through the lower leg 120. The pin is pre~
vented from passing through these parts by a ring 128 welded to the top of the pin. The ring also facilitates withdrawing . .
the pin to permit moving the wheel assembly into a transverse position rather than the towing position illustrated in Fig. 6.
Reference is now made to Fig. 7 to illustrate the wheel assembly inthe transverse position. It will be seen that pin 1~26 now passes through a plate 130 welded to the extension piece 114 and that consequently the wheel 124 will be in general alignment with the wheel on the other side of the stacker.
Wheel 124 can be returned to the towing position by simply with-drawing pin 126, rotating the wheel 124 into the towing posi-30 tion and reinserting the pin 126 so that it passes through ;
opening 132 in the extension piece 114.
~ .
~0657~4 In use, the feeder 22 (Fig. 2) and the stacker 24(Fig. 3) are towed and manoeuvred into the general position illustrated in Fig. 1. The stacker may be used with the wheels in the towing position or in many instances it will be prefer-able to rotate the wheels into the transverse position illus-trated in Fig. 7 so that the stacker can be manoeuvred sideways effectively swinging the stacker in a horizontal arc with refer- ,-ence to its feet 84 (Fig. 3). With the feeder and stacker in position, the ramps 40, 42 (Fig. 2) are lowered onto the ground so that trucks can then dump the material into hopper 28 (Fig.
1) for transporting the material first on the feeder and then on the stacker as previously described. Before commencing transporting of the material, it will be necessary to lower the feeder end to bring the feet 84 onto the ground.
It will be appreciated that by swinging the stacker horizontally the area of ground covered by the stacker will be increased. Consequently, if a large stack is to be built up the stacker can form a lower part of the stack without first elevating the material and drapping it from a height at one point equivalent to the eventual top of the stack. Because the materials are elevated only to a height slightly above that to which they will eventually come to rest, the power needed is substantially less than the power needed if the materials are to fall from the aforesaid one point.
Bulk materials such as sand are sometimes transported in warmer weather to a more convenient location where the mate-rials are stored under cover for use in winter. For instance ¦~
sand is stored in light prefabricated storage buildings for !
use in winter on road surfaces. Such storage limits problems which would be caused by rain freezing in the sand.
Because the storage buildings are not very strong,it is conventional to fill them by dumping the material at ground level in an entrance to the structure and to then push the material into a stack using a suitable bulldozer or other equipment. Each load must be moved onto the stack before another load of material is dumped. Also, as the stack is increased in height it naturally becomes more difficult to push the material onto the stack.
It is an object of the present invention to provide ;
apparatus for use in receiving such materials from a truck and for transporting the materials directly onto a stack within a light storage building. ~' Accordingly, apparatus is provided consisting essen-tially of a feeder which receives materials from trucks and a stacker which receives the materials off the feeder and trans-ports the materials to a point where the materials are dropped into a stack. Provision is made for adjusting the height from which the materials are dropped and the stacker has adjustable wheel assemblies to permit the stacker to be moved transversely `,-at the wheels so that the stacker swings in a horizontal arc , :

Reference is first made to Fig. 1 which illustrates apparatus according to a preferred embodiment of the invention : ' ~ ;! ' ' and indicated generally by the numeral 20. The apparatus con-sists of a feeder 22 which receives material from trucks and feeds the material onto a stacker for depositing the material inside a storage building 26. Such buildings are of a very light structure and commonly include internal retaining walls which in this instance have been omitted to simplify drawing.
The apparatus 20 permits material to be dumped into I -a hopper 28 on the feeder 22 and then conveyed to a receiver 30 on the stacker 24 before being elevated by the stacker in-side the building 26. Both the feeder and the stacker can be towed behind tractors and it is possible to ad~ust the posi- ~ `
tion of the stacker inside the building by adjusting the wheels on the stacker as will be described.
Reference is next made to Fig. 2 to describe the feeder 22 in more detail. The feeder 22 includes a chassis frame 32 extending longitudinally and supported by a pair of road wheels 34 and, when in use, by manually operated foot 36.
The frame 32 has a hitch 38 for towing and a rear portion of the frame is inclined upwardly from the wheels 34 to provide elevation for depositing materials off the feeder onto the stacker 24, part of which is shown in ghost outline in this ~ '!
figure.
The feeder includes a pair of ramps 40, 42 which are pivotally mounted on the chassis frame 32 for movement trans-versely so that they can be moved from a lowered position as drawn into a vertical stored position when the feeder is being towed. The ramp 40 can be seen in the stored position ~-in ghost outline in Fig. 2.
Materials are dropped into hopper 28 from a truck 1-which can be backed up the ramps 40, 42 and the hopper 28 ;: . .. . . . . .
. . ....
.' ' - '' ~65784 locates the materials and allows them to fall onto another part of a conveyor belt 44 which transports the materials longitud-inally past the wheels 34 and upwardly to an end roller 46 mounted at the end of chassis frame 32. The materials then fall downwardly beyond the roller onto the stacker 24. ,`-The conveyor belt 44 is driven from a gasoline engine and gearbox assembly 48 mounted on a platform 50 generally above wheels 34 and associated with the chassis frame 32. The -assembly 48 acts as a prime mover to drive a belt 52 which is .
in turn coupled to driven wheels associated with conveyor belt 44. Suitable supports for the conveyor belt 44 are provided such as supports 54 and 56 and tensioners 57 (one of which is .
seen) are provided at both ends of an end roller 59.
The conveyor belt 44 is driven at constant speed and `
as will be described the material which falls onto the stacker 24 can be distributed by moving the stacker while the feeder continues to move materials onto the stacker.
Reference is now made to Fig. 3 to describe the stacker 24. The stacker consists essentially of an elongated 20 boom 58 supported adjacent one end by a foot assembly 60 and `- ~
toward its opposite end by a pair of hydraulically extensible ~ -elements 62 (one of which is seen) and which are dependent from a sub-frame 64. This sub-frame extends between the foot ,~
assem,bly 60 and a cradle 66 to which is attached a pair of ~- ~
adjustable wheel assemblies 68 (one of which is seen in this - -view). Each of the wheel assemblies can be pivoted about one -of two parallel vertical axes so that the associated wheels move into positions such as that indicated in ghost outline.
The wheel assemblies will be more fully described with refer-ence to Figs. 6 and 7.
.~ . .. . .......... . . .
.
The cradle 66 includes an inclined upper support 70 on which the boom 58 can be rested when the stacker is in a rest position ready for towing as will be more fully described with reference to Fig. 4.
In Fig. 3 the stacker is in a position in which it is moving elevating material from the feeder 22 to a position for stacking the material. A prime mover 72 in the form a a gaso-line engine and gearbox is connected by a belt drive 74 to a drive system for a conveyor belt 76. The upper path of this conveyor belt extends from a first support roller 78 to an end support roller 80 so that material which drops into the re-ceiver 30 is carried by the conveyor belt to the remote end of the boom 58 and dropped over the roller 80. The elevation ;
of the roller 80 can be adjusted by utilizing the element 62 and sideways motion of the boom is possible using the wheel assemblies 68 in the ghost outline position. With the wheels in this position the boom can be moved sideways by applying a side force and the boom will then effectively rotate about the foot assembly 60. There will be minimal side motion of the 20 receiver 30 so that effectively the receiver continues to be -positioned under the end wheel 46 of the feeder 22 and material will continue to flow from the feeder 22 to the stacker 24.
Reference is next made to Fig. 4 to describe foot assembly 60 which is shown in Fig. 4 in a lowered condition which contrasts with the withdrawn condition shown in Fig. 3.
The foot assembly includes a wheel 82 on which the stacker rests when the foot assembly is in the lowered condition. A foot pad 84 is elevated above the wheel in this condition but, as seen in Fig. 3, the stacker rests on this foot pad with the foot assembly in the withdrawn condition.
: .. -.. .. .....
- ~ .' . ' , . . ..
, ' ', '" ': "'.'~' ~'" ' ' :
As best seen in Fig. 5, the foot assembly 60 is at-tached to the boom by a pair of parallel brackets 86 which ex-tend downwardly. A shaft 88 is fixed in the brackets 86 and foot pads 84 are suspended from the shaft 88.
The foot assembly 60 also includes a frame 90 which is pivotally mounted on the shaft 88 and which carries an in- Ij clined support plate 92 which provides a bearing surface for a ¦-rotatable wheel mount 94 carrying a wheel 96. ~he frame 90 also includes a trunnion 98 to which is coupled one end of a hydraulic actuator 100. The other end of this actuator is attached to a bracket 102 on a transverse member 104 of the boom.
It will be evident from Figs. 3, 4 and 5 that opera-tion of the actuator 100 will result in moving the foot assem-bly from the withdrawn position shown in Fig. 3 to the lowered position shown in Fig. 4. Similarly, the movement can be re-versed by bleeding hydraulic fluid from the cylinder 100 in a controlled fashion.
When the foot assembly is in the Fig. 4 position and the wheel assemblies 68 are in the straight-ahead or towing position, the stacker can be moved longitudinally. If it is dsired to tow the stacker, then the foot assembly 60 can be used to elevate a leading end of the stacker for positioning this end on a tow hitch of a truck or the like. The foot assem-bly is then raised to the Fig. 3 position to permit towing of the stacker with the boom in the lowered position as indicated in ghost outline in Fig. 3.
Reference is next made to Fig. 6 to describe one of the pair of adjustable wheel assemblies 68. As seen in Fig. 6, 30 the sub-frame 64 includes a heavy transverse element 106 which ~{: :
:............................ . . .. .
f ~--extends between a pair of parallel side elements 108 (one of which is seen in this view). Parts of the cradle 66 (Fig. 3) extend from the side elements 108 and rearward ends of these elements are connected to the extensible hydraulic elements 62 (Fig. 3).
A stub axle assembly llO is attached by a vertical fitted bolt 112 to a horizontal extension piece 114 which in turn is welded to one of the side elements 108. The stub axle assembly includes a reinforced U-shaped element 116 having re-spective upper and lower legs 118, 120 in sliding contact with the respective upper and lower surfaces of the extension piece 114. The U-shaped element 110 supports a stub axle 122 to which a wheel 124 (shown in ghost outline) can be attached in ;
conventional manner.
The stub axle assembly 110 is locked in position rela-tive to the extension piece 114 by a fitted pin 126 which extends - -downwardly through upper leg 118, through the extension piece 114, and finally through the lower leg 120. The pin is pre~
vented from passing through these parts by a ring 128 welded to the top of the pin. The ring also facilitates withdrawing . .
the pin to permit moving the wheel assembly into a transverse position rather than the towing position illustrated in Fig. 6.
Reference is now made to Fig. 7 to illustrate the wheel assembly inthe transverse position. It will be seen that pin 1~26 now passes through a plate 130 welded to the extension piece 114 and that consequently the wheel 124 will be in general alignment with the wheel on the other side of the stacker.
Wheel 124 can be returned to the towing position by simply with-drawing pin 126, rotating the wheel 124 into the towing posi-30 tion and reinserting the pin 126 so that it passes through ;
opening 132 in the extension piece 114.
~ .
~0657~4 In use, the feeder 22 (Fig. 2) and the stacker 24(Fig. 3) are towed and manoeuvred into the general position illustrated in Fig. 1. The stacker may be used with the wheels in the towing position or in many instances it will be prefer-able to rotate the wheels into the transverse position illus-trated in Fig. 7 so that the stacker can be manoeuvred sideways effectively swinging the stacker in a horizontal arc with refer- ,-ence to its feet 84 (Fig. 3). With the feeder and stacker in position, the ramps 40, 42 (Fig. 2) are lowered onto the ground so that trucks can then dump the material into hopper 28 (Fig.
1) for transporting the material first on the feeder and then on the stacker as previously described. Before commencing transporting of the material, it will be necessary to lower the feeder end to bring the feet 84 onto the ground.
It will be appreciated that by swinging the stacker horizontally the area of ground covered by the stacker will be increased. Consequently, if a large stack is to be built up the stacker can form a lower part of the stack without first elevating the material and drapping it from a height at one point equivalent to the eventual top of the stack. Because the materials are elevated only to a height slightly above that to which they will eventually come to rest, the power needed is substantially less than the power needed if the materials are to fall from the aforesaid one point.

1. Apparatus for use in receiving materials such as sand from a truck and for transporting the materials onto a stack within a storage building having an entrance at ground level, the apparatus comprising:
a feeder including: a chassis frame extending gener-ally longitudinally and having a towing hitch at one end and an inclined portion extending upwardly towards the other end;
a hopper intermediate the inclined portion and the towing hitch and having an open bottom; conveyor means extending longitud-inally under the hoppper and over said inclined portion; drive means coupled to the conveyor means and adapted to drive the conveyor means whereby materials from the hopper are moved longitudinally to said other end of the chassis frame and per-mitted to fall off this end of the chassis frame;
a stacker for collecting the materials falling from said other end of the feeder, the stacker including: a sub-frame extending longitudinally, and having a second towing hitch at one end and a supporting cradle at the other end; an elongated boom extending longitudinally and having a length larger than the distance between the cradle and the second tow-ing hitch; pivotal means coupling the boom to the sub-frame near the second towing hitch; elevating means coupled to the boom and to the sub-frame adjacent the cradle, the elevating means being operable to move the boom angularly about said pivotal means between the rest position in which the boom is supported by the cradle and an elevated position in which the boom is inclined and above the cradle; a second conveyor means extending longitudinally along substantially the full length of the boom from a first end of the boom near the second towing hitch to a second end of the boom; a second drive means coupled to the second conveyor means and adapted to drive the second conveyor means whereby said materials falling from said other end of the feeder can be collected on said second conveyor means adjacent said first end of the second conveyor means and trans-ported by the second conveyor means to the second end of this conveyor means where the materials are then elevated and per-mitted to fall onto a stack inside the storage building; and a pair of adjustable wheel assemblies attached to the sub-frame below the cradle, each of the assemblies including a road wheel and means coupling the road wheel to the sub-frame, said coupling means being adjustable relative to the sub-frame for positioning the road wheel in either one of a first position in which the road wheel is aligned for moving the stacker longitudinally and a second position in which the road wheel is aligned for moving the stacker transversely at the wheels so that with the wheels in this second position the stacker can be moved such that the boom swings in a horizontal arc generally about the first end of the boom.
a feeder including: a chassis frame extending gener-ally longitudinally and having a towing hitch at one end and an inclined portion extending upwardly towards the other end;
a hopper intermediate the inclined portion and the towing hitch and having an open bottom; conveyor means extending longitud-inally under the hoppper and over said inclined portion; drive means coupled to the conveyor means and adapted to drive the conveyor means whereby materials from the hopper are moved longitudinally to said other end of the chassis frame and per-mitted to fall off this end of the chassis frame;
a stacker for collecting the materials falling from said other end of the feeder, the stacker including: a sub-frame extending longitudinally, and having a second towing hitch at one end and a supporting cradle at the other end; an elongated boom extending longitudinally and having a length larger than the distance between the cradle and the second tow-ing hitch; pivotal means coupling the boom to the sub-frame near the second towing hitch; elevating means coupled to the boom and to the sub-frame adjacent the cradle, the elevating means being operable to move the boom angularly about said pivotal means between the rest position in which the boom is supported by the cradle and an elevated position in which the boom is inclined and above the cradle; a second conveyor means extending longitudinally along substantially the full length of the boom from a first end of the boom near the second towing hitch to a second end of the boom; a second drive means coupled to the second conveyor means and adapted to drive the second conveyor means whereby said materials falling from said other end of the feeder can be collected on said second conveyor means adjacent said first end of the second conveyor means and trans-ported by the second conveyor means to the second end of this conveyor means where the materials are then elevated and per-mitted to fall onto a stack inside the storage building; and a pair of adjustable wheel assemblies attached to the sub-frame below the cradle, each of the assemblies including a road wheel and means coupling the road wheel to the sub-frame, said coupling means being adjustable relative to the sub-frame for positioning the road wheel in either one of a first position in which the road wheel is aligned for moving the stacker longitudinally and a second position in which the road wheel is aligned for moving the stacker transversely at the wheels so that with the wheels in this second position the stacker can be moved such that the boom swings in a horizontal arc generally about the first end of the boom.
2. Apparatus as claimed in claim 1 and further comprising a foot assembly attached to the sub-frame of the stacker adja-cent said first end of the boom for supporting said pivotal means.
3. Apparatus as claimed in claim 2 in which the foot as-sembly includes a frame pivotally coupled to the sub-frame about a transverse axis; a wheel attached to an outer end of the frame;
and an actuator coupled to the frame near the last-mentioned wheel and to the sub-frame for use in moving the frame angularly so that this wheel is moved between a withdrawn position in which the frame is generally parallel to the sub-frame and a lowered position in which the frame is generally perpendicular to the sub-frame and the last-mentioned wheel is on the ground, this movement from the raised to the lowered position being sufficient to cause the boom first end to be raised for attaching the second trailer hitch to a tractor and the stacker then being in a position for manoeuvring the stacker.
