发明名称 Vertically stored dock leveler
摘要 A vertically storable dock leveler apparatus includes a generally planar ramp member mounted on a frame by a hinge connection which includes spaced apart hinge plates secured to the frame, each having hinge pin receiving bores formed therein. An elongated cylindrical hinge pin is secured to the ramp and extends through the receiving bores of the hinge plates. The ramp is provided with elongated clearance slots formed therein providing clearance for the hinge plates when the ramp is assembled to the frame. Linearly extensible gas springs are interconnected between the ramp and the frame for biasing the ramp toward a vertically oriented stored position. An elongated actuating member is adapted to be releasably connected to a member mounted on one lateral edge of the ramp and also disposed in a socket member mounted on the frame for use in moving the ramp between working and stored positions and for retaining the ramp in its stored position, respectively. The ramp and actuating member may be secured together with a padlock to lock the ramp in the stored position.
