Abstract: The invention concern a method for mounting a car drive machine (9), especially for elevators having no machine room, the drive machine (9) being to be affixed to a structure in the hoistway, characterized in that it successively consists of positioning said drive machine (9) on a support (23) positioned so as to be suitably on the top of the elevator car (7) and being able to move transversally, to lift the elevator car (7) until the machine is slightly above said structure, to move the support (23) with the machine (9) transversally and outwardly so as to position the machine (9) immediately above its fixing position, to lower the car (7) so as to place and fix the machine (9) on said structure, and to bring said support (23) back transversally so as to free it from the machine (9).

Abstract: An elevator system includes a hoistway that extends upwardly from a pit area to an upper hoistway area. A support plate extends across a lateral width of the hoistway and is mounted between a machine base and a guide rail assembly. A hoist tool is mounted within the hoistway near the upper hoistway area for lifting the machine base and rail assembly upwardly through the hoistway from the pit area to the top of the hoistway. The hoist tool supports a first set of pulleys and the support plate supports a second set of pulleys. A cable is threaded through the first and second sets of pulleys and is connected to a hoist machine for lifting the machine base and guide rail assembly to an installation position in the upper hoistway area via the hoist tool and pulley system.
