foir the invention entitled "ROPE HAULAGE MACHINE" The following stateme~nt is a full. description of this invention, including the best method of perfomuing it known to me; ,dda ,4h53)~~ k.

r S- 1A- The invention relates to a portable rope haulage machine with a driving motor, a cutch, a gear unit, and a rope drive pulley.

Small motor-driven lifting appliances that preferably serve to move loads vertically and consequently are only of limited application are in principle known.

This applies also to electric hoists or winches and hoisting units with a rope drum and additional brakes if necessary. In addition to this the known motor-driven lifting appliances are frequently bulky in construction and on account of their heavy weights are difficult to manipulate. Moreover a combined assembly for use, for example, as a lifting appliance, a rope drive and a dru:n drive is not possible.

Here the invention provides assistance.

The present invention seeks to create a portable rope haulage machine of the type initially described that is notable for compact construction and light weight, and also for high pulling power, high rope speed and ease of manipulation, and which can be employed as a lifting appliance as well as a rope drive or rope railway drive and drum drive etc.

S. In accordance with tht present invention, therefore, there is provided a portable rope haulage machine including a driving motor, a clutch, a gear unit, and a rope drive pulley, wherein said clutch is constructed as a disc clutch-cumbrake that is adapted to be released by hand, said gear unit is constructed as an epicycli gear, said disc clut.h is located on an output shaft of said driven epicyclic S. gear, a driving pinion for said rope drive pulley is Located between said epicyclic gear and said dise clutch attached to the output side of the latter, and said rope drive pulley is overhang and possesses a toothed wheel meshing with said driving pinion.

The disc clutch, in which releasable pressure units, for example cup springs, are included may be operated as a contollable lowering brake by means of a hand lever.

These features of the invention in the first place have the result that loads can be lowered with the rope haulage machine according to the invention by their own weight and with controlled braking force. In fact an extremely -2closely-controlled braking system is provided by the disc dclutch, as the load can be lowered or raised sensitively and accurately, so that for example the insertion of bolts, screws, machlne parts and the like can take place with millimetre accuracy. If the driving motor has no inherent braking action as in a petrol or compressed air motor) then the planet wheel carrier of the e 1 icyclic gear, with built-in ratchets, serve to block reverse motion. The ratchets only permit rotary motion during lifting, as soon as the drivivg shaft of the epicyclic gear moves in the reverse direction they immediately lock positively in the internal gear and block the driving system, which for lowering purposes can then be unlocked by manually releasing the disc dclutch. The epicyclic drive makes an extremely great reduction ratio possible. This applies particularly when the driving motor drives the epicyclic drive via a V-belt reduction and possibly with the interposition of a reduction gear. An internal combustion engine is the preferable form of driving motor but the use of a compressed air motor or an electric motor is possible. The 0: total gear 0**00 o..o

Fig.4 i I i i t~d~ 3 reduction can amount to 1 600. The combination of the epicyclic gearing, thjt is light in weight, and the disc clutch ensures high efficiency with minimum frictional resistance, so that the rope haulage machine can work perfectly with high pulling power, high rope speed and small total weight, even at a great height above sea-level and is consequently particularly suitable for erectors of rope S* railways, steel constructions and obstacles to avalanches.

*The overhung-mounted rope drive pulley makes it rO'" possible to insert an endless spliced rope and consequently S: the rope haulage machine according to the invention can be used not only as a lifting appliance but also as a rope drive or rope railway drive. In fact an endless spliced rope can be inserted onto the rope drive pulley at any desired eo position without having to cut the rope, thread a rope end through or dismantle the rope haulage machine..

In addition, the particularly compact construction obtained by the arrangement of epicyclic gear, disc clutch and rope drive pulley, can be further improved by having a hollow shaft carrying the driving pinion for the rope drive pulley, attached to the output side of the disc clutch, and running on the driving shaft of the epicyclic gear.

Moreover a rope guidance pulley can be associated with the rope drive pulley, as can a tiltably-mounted rope pressure pulley urged into the rope groove of the rope drive pulley and operating in proportion to the rope tension in the taut strand of the rope. More certain transfer of the driving or traction force to the rope concerned is thereby achieved.

The rope drive pulley preferably possesses insertion i" i.

I

j~ L holes for locking bolts and for an inserted-bolt coupling to drive any desired appliance or plant. The appliances and equipment thereby driven can with no change in power be bl cked in the stationary position, or with constant moment be moved backwards by the disc clutch, or with decreasing torque can be released. In this manner the rope haulage machine according to the invention can form at the same time, for example, a bobbin drive or a drum drive, because the drum *n question can be driven by means of a driving chain via a

I

1 chain pinion on the inserted-bolt coupling. Obviously the drum possesses a corresponding chain wheel for this purpose.

Thus by including an additional chain drive the direct drive of large bobbins or drums is possible with the rope haulage machine according to the inventiun, whilst the machine itself has a weight of less than 30 kg. In consequence the function of a bei- k drive is combined with the function of a lifting appliance and that of a rope drive or rope railway drive.

The epicyclic gear, the disc clutch and the rope drive pulley are supported in a housing, and an axially-slidable housing cover for the rope drive pulley is mounted on the clutch housing. Consequently the housing can be opened without difficulty to insert an endless rope on the rope drive pulley. Here there is also the possibility of designing the housing cover to prevent the rope from slipping out and for this purpose it possesses internally, guides, sliders or rollers of plastics, distributed over a portion of the periphery of the rope drive pulley, so that the rope cannot get out of the rope groove in the rope drive 1, r r

pulley.

According to a modified form of construction of the by eA\ec+rnc MCoior inventiornusing an motele with magnetic brake as driving motor the disc clutch can be omitted. In this case a hand lever is unnecessary, as the -otor works in both rotational directions. Lowering or lifting of the load then taken place electrically by reversing the direction of rotation.

peber- Finally, a single suspension point or anchorage point is provided for the rope haulage machine according to the f invention, so that the latter can work in any position, as it sets itself automatically in the line of action due to the single anchorage point.

As the result a rope haulage machine is realized that i, on account of its small weight can be used as a portable machine and consequently is easy to manipulate.

Nevertheless the transmission of large traction forces at high rope speeds is ensured. Precise lifting and lowering of loads is also possible. In addition to this a universal drive for ropes, rope bobbins, rope winches and other assemblies that have to be driven is realized. Thus, the rope haulage machine according to the invention can for example be used for steel-framed buildings and similarly for building rope railways or pylons. The same applies to building in reinforced concrete, bridge-building, and to lifting and hauling work in general. Also the Use of the rope haulage machine according to the invention can be considered f0or the rescue services and in forestry (lifting ersons and loaes. righting overturned vehicles, dragging rees, tree-trunks, blocks of stone etc.). The same applies V -0/0 6 to the bul 4 i-ak of avalanche protection constructions and to fortification work. Even in cable duct construction the rope haulage machine according to the invention is suitable for hauling conductors, cables, pipe units and the like.

Finally the rope winch according to the invention also functions as a salvage winch, for example for heavy duty vehicles, or as an erection equipment for pioneer troops.
