ABSTRACT:
Elevator guide rails are installed in the hoistway by jacking them up along the hoistway walls from the hoistway pit. A pair of jack assemblies are positioned adjacent to the side walls of the hoistway to which the rails are to be secured. Each jack assembly includes two jacks, one atop the other, and the two assemblies are connected together by an I-beam which extends across the hoistway. The lower jack in each assembly includes a rail gripper which allows the rails to move upwardly in the hoistway, but not downwardly. The upper jack includes a rail gripper which grips the rails as the jack is raised, and releases the rails as the jack is lowered.
