Methods and apparatuses for lifting elevator cars during installation
Abstract:
Climber motors are a form of temporary winch that can be used before a permanent elevator drive system is installed at the top of a hoistway. A mount to be employed with such a climber motor may include a frame having a base, a lower portion, and an upper portion. The upper portion may support a lower plate, which lower plate supports sleeves, which sleeves in turn support an upper plate. The frame and the climber motor may be positioned within an elevator cab such that the sleeves extend upwards through apertures in a canopy of the elevator cab. Once the upper plate is positioned between the sleeves and a crosshead above the elevator cab, the climber motor may be engaged to cause the sleeves to exert an upward force on the crosshead and thereby lift the elevator cab in the hoistway.
