ABSTRACT:
An improved height adjustment mechanism comprises a height adjustment arm permanently affixed to a wheel mounting member, the wheel mounting member pivoting around a bracket which is permanently connected to the underside of a longitudinal structural member. The height adjusting arm comprises two opposed parallel guide plates, arranged vertically, and attached at their lower extreme to the wheel mounting member. The height adjustment arm is raised and lowered by operation of height adjustment means attached to the top of the arm, the height adjustment means having both ends pivotally attached to the top side of the platform frame member. The guide plates of the height adjustment arm are pierced through with a series of opposing pairs of support openings, to which a support pin may be fitted. Placement of the pin then serves as a physical stop for the underside of the longitudinal structural member as the frame is lowered. The weight of the platform is thus borne by the support pin and the wheel arm. Detachment or release of pressure within the hydraulic means can then occur safely, leaving the platform in its height-adjusted position.
