In this embodiment, elevator cage utilizes 1: 1 suspension than realization, so traction wheel Wheel limit speed is consistent with the speed of cab. On the other hand, balance weight hangs with 1: 2 speed ratio, therefore The speed of balance weight equals half of traction wheel wheel limit speed. Compensates rope 10 is in known manner fixing To the bottom of elevator cage 2, it is via the angle pulley 12 in the bottom that promotes the path and be connected to flat The angle pulley 58 of weight lower end and arrive to promote the bottom in path is connected to rope clamp at this place's rope and holds On the device (rope clamp) 26. Thereby compensates rope and elevator rope are suspended on electricity with 1: 1 speed ratio On one side of ladder cab, and be suspended on the side of balance weight with 1: 2 speed ratio. Hoisting machine and The compensates rope aspect, elevator is worked in a usual manner.

Elevator rope in building process untapped that part of 6 free suspensions under clamper 24, And extra rope is wrapped on the rope spool in the rope supply 8. Rope supply 8 preferred status In the horizontal plane place of first temporary position of machine room table top or the bottom of following building. Similarly, folder The extra section 14 of holding the compensates rope behind the device 26 leaves on the rope spool in the rope supply 16.

Hypervelocity limiter of speed rope 32 1 ends are connected to elevator cage, and via in the bottom that promotes the path Angle pulley 35 arrives on the hypervelocity limiter of speed wheel 34. Hypervelocity limiter of speed rope 32 is fastened to the cab top Clamper 36 on, and its part 38 of freely restricting leaves the hypervelocity speed limit that is positioned on the cab top 42 in In the device rope supply 40.

Provide for control panel 52 and elevator control at machine room table top or near another table top 48 it The space of unit 50 processed. Table top 48 is connected on the table top 22 in the following manner, and namely two table tops can Progress with construction work raises.
