Among the figure, the 1st, access trunk, 2 are provided in a side of a pair of car guide rail in the access trunk 1, the 3rd, a pair of car belt pulley 6 that by the car of car guide rail 2 guiding, lifting access trunk 1 in, this car 3 has car frame 4, be bearing in cage 5 on the car frame 4, rotation is located at the bottom of cage 5 freely, open and close the car door 7 of cage 5 gangways and be located at the top of cage 5, the opening and closing device 8 of driving car door 7.In addition, car frame 4 has a pair of vertical post 4a and at the upper fixed of the cage 5 back timber 4b between vertical post 4a.

9 are provided in a side of a pair of weight guide in the access trunk 1, the 10th, along weight guide 9 and the balance weight of lifting in access trunk 1, the 11st, rotate the counterweight belt pulley that is located at balance weight 10 tops freely, 12 be provided in a side of on the bottom of access trunk 1, the counterweight energy disperser of supporting balance weight 10, expression is supported balance weight 10 and state after being depressed in Fig. 1.In addition, the car of supporting car 3 is omitted with the diagram of energy disperser.

The 13rd, be fixed on the winch erecting bed between the top of a pair of weight guide 9, the 14th, the top in access trunk 1 is located on the winch erecting bed 13, makes the winch of car 3 and balance weight 10 liftings, and this winch 14 has: carry the reductor 15 on winch erecting bed 13; Output shaft bonded assembly hauling block 16 with this reductor 15; Be connected, drive the electrical motor 17 of hauling block 16 by reductor 15 with the input shaft of reductor 15.

In addition, as shown in Figure 2, when car 3 and winch 14 vertical projections are to the face of level, reductor 15 and hauling block 16 are configured in outside the view field of car 3 (not with car 3 position overlapped), and the part of electrical motor 17 is configured in the view field of car 3 (with car 3 position overlapped).In addition, as shown in Figure 1, the face of the electrical motor 17 relative with the top ceiling of cage 5 is positioned at the top of the bottom of reductor 15 and hauling block 16.The 18th, reductor 15 is fixed on a pair of fixed arm on the sidewall 1a of access trunk 1.

The 19th, the hoist cable of suspension craning cab 3 and balance weight 10 in access trunk 1, this hoist cable 19, its cage side end 19a, counterweight side end 19b are connected with the top of access trunk 1 and the bottom of winch erecting bed 13 respectively.In addition, hoist cable 19 begins order with a pair of car belt pulley 16, hauling block 16 and counterweight belt pulley 11 around hanging to counterweight side end 19b from cage side end 19a.The 20th, the ground at the riding place of elevator, the 21st, the door at the riding place of elevator.

In this elevator,, shown in long and two-short dash line among Fig. 1,, can guarantee the space so also go up in the shift position, the top of car 3 owing to car 3 rises upward when balance weight 10 drops to bottom shift position and makes counterweight with after energy disperser 12 compress fully.Here, the cat head size OH among Fig. 1 is: OH=H1+d10+M+d20.

But H1 is the height dimension till the topmost (being the top ceiling of cage 5 here) of equipment on the immediate car 3 of equipment (being electrical motor 17 here) of 3 when rising and car 3 tops from the riding ground 20 of the elevator of the superiors to car.In addition, d10 is cage 5 top ceilings after rising and the size between the electrical motor 17, and M is the diameter (specifically about 200mm) of electrical motor 17, and d20 is the size between the top ceiling of the topmost (being electrical motor 17 here) of winch 14 and access trunk 1.

Suppose the top that winch 14 all is configured in car 3, then the height (about 600mm) of height of winch supporting station 13 (about 150mm) and winch 14 adds the cat head size.And this moment, the diameter package of electrical motor 17 is contained in the height of winch 14.

Therefore, in example 1, the cat head size is reduced to (height of winch supporting station 13)+(height of winch 14)-(diameter of electrical motor 17) than the occasion that winch 14 all is configured in directly over the car 3.Specifically, adopt the configuration of example 1, the cat head size is reduced to about 150mm+600mm-200mm=550mm.

In addition, under the situation of winch 14 band reductors 15, because but ratio speed reducer 15 or hauling block 16 constitute electrical motor 17 littlely, so under the situation of not using winch supporting station 13 (for example suspending the situation of winch 14 in midair), also can make the cat head size be reduced to (height of winch 14)-(diameter of electrical motor 17) from the top ceiling of access trunk 1.

In addition, when the uppermost position of electrical motor 17 is in the also low position of topmost than winch 14 other parts, then the size from the topmost of electrical motor 17 to the topmost of winch 14 just with the cat head size addition of following formula.To this, be set as the height identical or, then can reduce the cat head size very effectively than its high position with the topmost of winch 14 other parts by position with the topmost of electrical motor 17.

Also have, as shown in Figure 2, when when winch 3 and car 4 vertical projections are to the face of level, are configured to overlapping fully situation with winch 3 and car 4 and compare, in the structure of example 1, restricted relatively access trunk area can increase the floor space of cage 5.

In addition, be fixed on the upper end of weight guide 9, so can effectively utilize the upper space in the access trunk 1 to dispose winch 14 owing to can carry the winch erecting bed 13 of reductor 15.

In addition, act on bigger load on the hauling block 16 to the directive effect that makes winch 14 overturnings, but reductor 15 is fixed on the sidewall 1a of access trunk 1 by fixed arm 18, promptly, one end of fixed arm 18 is fixed on the sidewall 1a, the other end is fixed on the housing of reductor 15, can prevent from more reliably thus to make winch 14 overturnings because of the load that acts on the hauling block 16.
