Upper level in hoistway 1 is provided with actuating device 6, and this actuating device 6 produces the propulsive effort that is used to make car 4 and counterweight 5 liftings.Actuating device 6 is configured in the zone of car 4 in the vertical plane of hoistway 1.In addition, actuating device 6 has: actuating device main body 7 and driving rope sheave 8, this driving rope sheave 8 is the center rotation by actuating device main body 7 with the S. A. that extends along the vertical direction.And actuating device 6 is slim towing machine, its along the size of axis direction (along the direction of the S. A. that drives rope sheave 8) less than the size of (perpendicular to the direction of axis direction) radially.In this example, actuating device 6 is configured to make driving rope sheave 8 to be positioned at the top of actuating device main body 7.
Both sides in the bottom of car 4 are provided with a pair of car hanging wheel 9,10.Each car hanging wheel 9,10 is configured to: in the vertical plane of hoistway 1, with respect to the central point (Fig. 2) that connects the line segment between each car guide rail 2.
Top in hoistway 1, and above car 4, be provided with the first cage side diversion sheave 11 and the second cage side diversion sheave 12.The S. A. that the first and second cage side diversion sheaves 11,12 extend with along continuous straight runs respectively is the center rotation.The first cage side diversion sheave 11 is configured in the top of a car hanging wheel 9.And the second cage side diversion sheave 12 is configured in the top of another car hanging wheel 10.

Each main rope 17 is made by the wire rod of many steels of twisted.The diameter of each wire rod is littler than common gauge or diameter of wire.Thereby it is very high that each main rope 17 flexible is able to.And, flexible in order further to improve, also can make each main rope 17 be synthetic fiber rope.
Below, action is described.When driving rope sheave 8 was rotated, each main rope 17 moved corresponding to the rotation that drives rope sheave 8.Thus, car 4 and counterweight 5 are guiding lifting in hoistway 1 by each car guide rail 2 and each counterweight guide rail 3 respectively.
Next, describe being applied to the axial load that drives on the rope sheave 8.Because car 4 and counterweight 5 are by main rope 17 suspentions, therefore, main rope 17, from driving the part of rope sheave 8 to the first cable end 17a side, be applied in the first rope tension T1, main rope 17, from driving the part of rope sheave 8 to the second cable end 17b side, be applied in the second rope tension T2.
Because weight W 1 and the first rope tension T1 and the second rope tension T2 sum balance of counterweight 5, therefore, following formula is set up:
T1+T2＝W1 …(1)
Because being applied to the axial load MT that drives on the rope sheave 8 is the first rope tension T1 and the second rope tension T2 sum, therefore, according to formula (1), following relational expression is set up:
MT＝T1+T2＝W1 …(2)
That is, axial load MT equals the weight W 1 of counterweight 5.
And, (the total weight of the car weight Wa of car 4 self and the load carrying ability Wb of the Loaded goods in the car 4) W2 because the total weight of car 4 sides, with second rope tension T2 of car hanging wheel 9 sides and the second rope tension T2 sum balance of another car hanging wheel 10 sides, therefore, the second rope tension T2 is expressed from the next:
T2＝(W2)/2 …(3)
In addition, according to formula (1) and formula (3), the first rope tension T1 can be expressed from the next:
T1＝W1-(W2)/2 …(4)
In this example, be the half of Maximum Loading Capacity Wbmax at load carrying ability Wb, weight W 1 balance of the total weight W2 of car 4 sides and counterweight 5.
Here, by formula (3) and formula (4) as can be known, the first rope tension T1 and second rope tension T2 size separately are different sometimes.So the interval between the first and second counterweight rope connecting portions 13,14 is big more, the unbalance load that acts on the counterweight 5 is just big more, and the antagonistic force that acts on each counterweight guide rail 3 is also just big more.Therefore, according to the interval between the first and second counterweight rope connecting portions 13,14, the noise that produces because of counterweight 5 and contacting of each counterweight guide rail 3 may become greatly, and perhaps the life-span of counterweight guide rail 3 may shorten because of wearing and tearing.
Therefore, interval between the first and second counterweight rope connecting portions 13,14 is set in the predetermined scope, in this preset range, can allow owing to act on the harmful effect that unbalance load produced of counterweight 5, for example the wearing and tearing of noise and counterweight guide rail 3 etc.And in this example, the plumb bob vertical of the first and second counterweight rope connecting portions 13,14 and the center of gravity by counterweight 5 closely is configured on the counterweight 5.

Since total weight W2 and the first rope tension T3 and the second rope tension T4 sum balance of car 4 sides, so following formula is set up:
T3+T4＝W2 …(5)
Owing to be applied to the axial load MT that drives on the rope sheave 8, be the first rope tension T3 and the second rope tension T4 sum, therefore,, have following relation to set up according to formula (5):
MT＝T3+T4＝W2 …(6)
That is, axial load MT equals the total weight W2 of car 4 sides.
And identical with embodiment 1, the first rope tension T3 and the second rope tension T4 represent with following formula respectively:
T3＝(W1)/2 …(7)
T4＝W2-(W1)/2 …(8)
