Abstract:
The elevator assembly is designed to operate an elevator car in a building under construction. The assembly includes a unitary frame having a machine room module with a machine, traction sheave, deflection sheave, spare cable spools, and a payout sheave module with cable clamps and cable payout sheaves. The frame is periodically shackled to the car and both are craned up several floors in the building as the latter rises. After the frame is set in place, extra cables are fed off of the cable spools via the payout sheaves to reconnect the counterweight to the car.

Abstract:
The elevator assembly is designed to operate an elevator car (58) in a building under construction. The assembly includes a unitary frame (4) having a machine room module (8) with a machine, traction sheave (12), deflection sheave (52), spare cable spools (14), and a payout sheave module (24) with cable clamps (28) and cable payout sheaves (30, 32). The frame (4) is periodically shackled to the car (58) and both are craned up several floors in the building as the latter rises. After the frame (4) is set in place, extra cables are fed off of the cable spools (14) via the payout sheaves (30, 32) to reconnect the counterweight (42) to the car. According to the method, before paying out of the spare cables (C) from the cable spools (14), the cables (C) are engaged by a hand break (34) to hold the cables (C) while unclamping said cables (C) from the cable clamps (28); and, during the paying out of cable from the cable spools (14), brake means (31) are used to control the speed and the smooth running of the cables (C) when the counterweight cable sheave (44) is lowered in the hoistway. When the counterweight cable sheave (44) has reached the remainder of the counterweight assembly (42), the cables (C) are reclamped to the clamping means (28) before the elevator car (58) is unfastened from the elevator assembly frame (4).
