ELEVATOR SYSTEM INCLUDING A CAR STOP FOR MAINTAINING OVERHEAD CLEARANCE

摘要

An exemplary elevator system includes an elevator car. At least one guiderail is situated for guiding movement of the elevator car. A machine mount is supported by the guiderail near a top of the guiderail. A car stop is supported on the elevator car. The car stop is selectively moveable between a first position and a second position. In the first position the car stop allows the elevator car to travel to a maximum vertical position. In the second position the car stop is situated to contact the machine mount to prevent the elevator car from reaching the maximum vertical position.

主权项

1. A car stop for maintaining a minimum safe working area above an elevator car located in a hoistway, the car stop comprising:
a plurality of leg members, each leg member having a first end configured to be pivotally attached to a top of the elevator car, and a second end; a cross member, configured to be secured to the second end of each of the leg members; and a plurality of mounting brackets, configured to be secured to a machine mount located proximate a top of the hoistway and secured to a plurality of guide rails, wherein the plurality of legs are configured to pivot between a first position in which the cross member is proximate the top of the elevator car and a second position in which the cross member is proximate the plurality of mounting brackets, and wherein a mechanical strength of the system is sufficient to prohibit upward movement of the elevator car when the plurality of legs are in the second position.
