Abstract
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.
