Abstract
A mobile loading dock for a vehicle including a load-bearing, fixed frame with a support plate connected to diagonal supports and horizontal support members. The dock has a planar ramp member with an underside including a wheel assembly. The assembly has a tension spring and hydraulic member attached to the underside. The tension spring exerts a pulling force and the hydraulic member exerts a pushing force. The combined forces are directionally disposed to erect the assembly when the lower end of the dock is raised from a resting position in contact with the ground surface to a mobile position.
