Elevator pit barrier

摘要

An elevator installation includes a car within a shaft, a buffer mounted in a pit of the shaft and a barrier located in the pit surrounding or within an area wherein a vertical clearance between the pit floor and the car or equipment mounted thereon is less than a regulatory threshold value when the car fully compresses the buffer. The barrier acts to physically deter personnel within the pit from inadvertent presence in the area of reduced vertical clearance.

主权项

1. A method for restraining personnel on a pit floor in an elevator pit from entering from an adjacent pit floor area into an area of potentially reduced vertical clearance between the pit floor and a component mounted to an underside of an elevator car, comprising the steps of:
establishing a minimum required vertical clearance between the pit floor and the elevator car when a compressible buffer of a buffer system in the elevator pit is fully compressed by the elevator car and the car rests upon the buffer system above the pit floor; determining a determined area of the pit floor below the component wherein a vertical clearance between the pit floor and the component is less than the minimum required vertical clearance when the compressible buffer is fully compressed by the car; and selectively erecting a barrier separate from the buffer system on the pit floor and extending upwardly therefrom at a location within or surrounding the determined area and spaced from the buffer system to physically deter personnel within the pit and in the adjacent pit floor area outside the determined area from inadvertently entering the determined area.
