A dock leveler includes a pivotally mounted ramp and a lip member pivotally mounted to the distal end of the ramp and moveable between an extended position and a depending position for forming a path between a loading dock and a loadbed of a vehicle. A motor operated linear power screw type actuator is connected to the ramp for moving the ramp to an elevated position and includes an extensible tube member which is engageable with a second tube in telescoped relationship in such a way that the actuator tube may be controlled to be retracted after position...
[ What is claimed is:] [1.] A dock leveler for forming a path between a loading dock and a loadbed of a vehicle for transferring cargo therebetween, including:a frame;a generally planar ramp including hinge means for pivotally moving said ramp from a generally horizontal storage position to an elevated position about said hinge means; andan actuator operably connected to said ramp and including a drive motor drivingly connected to a linearly extensible member for causing said ramp to move to an elevated position, a first guide tube operably connected to ...
