发明名称 Elevator car assembly having an adjustable platform
摘要 An elevator car assembly ( 14 ) includes a frame ( 28 ) having a horizontal plank beam ( 36 ) beneath a platform assembly ( 34 ). A plurality of braces ( 44 ) support the platform assembly ( 34 ) relative to the frame. The braces ( 44 ) include at least one slot associated with a fastener ( 58, 60 ) to facilitate adjusting a position of the platform assembly ( 34 ) relative to the frame. Adjusting the position of the platform assembly ( 34 ) allows for leveling the car frame assembly in an economical manner that does not require the introduction of weights or other expensive balancing measures.
