Mobile Loading Dock with Wheel Assembly |
摘要 |
A mobile loading dock including a planar ramp member having an underside with a wheel assembly. The wheel assembly includes a tension spring, hydraulic member, a leg hingedly attached to the ramp underside and a wheel attached to the leg. The tension spring exerts a pulling force on the leg and wheel and the hydraulic member exerts a pushing force. The combined forces are directionally disposed to erect the wheel assembly when the lower end of the mobile loading dock is raised from a resting position in contact with the ground surface to a mobile position. |
