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.
