A temporary pulley assembly is fastened to the ceiling of a lift hoistway, and is used to raise the sheave crossbeam, sheaves, car, and counterweight assembly to the hoistway ceiling. The crossbeam is a telescoping member which is extended to fit into pockets in the hoistway side walls. Installers working on the roof of the car can fix guide rails to the hoistway walls as the entire assembly is being raised en masse. When the assembly reaches the top of the hoistway, the hoisting cables or ropes are properly fastened to the various lift sheaves, and to the hoistway ceiling.
