Lift truck having improved single mast and bearing wheel assembly |
摘要 |
A fork lift assembly is supported against a single rectangular mast by at least four separate bearing wheel assemblies. The rectangular mast is positioned relative to the fork lift assembly so that a front edge of the rectangular mast is positioned directly in line with the torque forces exerted by the load. Since the bending forces applied to the mast by the lifted load are in the direction of the edge of the mast, as opposed to the side of the mast, the mast can support a greater load. Further, the positioning of the four bearing wheel assemblies contacting each of the four sides of the masat inherently eliminate any side-to-side and twisting play in the fork lift assembly.
