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.
