ABSTRACT:
The working platform is set up on the highest floor slab in a building being erected so as to cover the elevator hoistway. Extensible finger beams serve to position the platform properly over the hoistway. The platform serves as a template for rail plumb lines and landing door assemblies, and carries winches which are used to lift the rails and door assemblies into place in the hoistway. A false car is suspended in the hoistway below the platform and runs up and down in the hoistway on a hoisting rope. Workers use the false car to install rails and landing door assemblies which have been lifted into place by the winches on the working platform.
