  • Crane access staircase and mounting system
    Patent number: 9222306
    Abstract: An access system for facilitating access to an elevated deck of a mobile crane includes a staircase having a support post defining an axis of inclination. A plurality of ascending steps is connected to the at least one support post, and a mounting bracket is pivotally coupled to an upper end of the at least one support post. The staircase is pivotable about a longitudinal axis such that a lower end of the at least one support post is induced to move in a lateral direction in response to pivotal motion of the at least one support post. A caster is coupled to the lower end of the support post for supporting the staircase on a ground surface. The caster supports the staircase on the ground surface throughout longitudinal movements of the staircase and lateral movements of the staircase induced by vertical movements of the mobile crane.
