Abstract

A work platform for use with an aerial work platform to accomplish a work activity at an elevated location. The work platform has a deck with a floor, an upwardly extending guardrail assembly around the floor and a work step pivotally attached to the guardrail assembly to move between a vertical storage position and a horizontal work position to allow a worker to reach higher than possible from the floor. A step support mechanism supports the work step in its work position. The step support mechanism can be support legs that contact the floor or cables which are connected to the guardrail assembly. The guardrail assembly has a movable upper assembly that is moved upward for safe use of the work step. The aerial work platform has a self-propelled chassis and a lift mechanism that move and elevate the work platform using operator controls on the work platform.
