HOLD-DOWN DEVICE FOR DOCKBOARD ABSTRACT OF THE DISCLOSURE A dock leveler having a swingable ramp positioned for engagement with a truck bed. The front end of the ramp is nor- mally urged upwardly by a spring-urged lift arm mounted within a pit in the dock. The ramp is movable through a selected angle, both above and below a horizontal position, to accommodate differ- ent truck bed heights and to adjust to variations therein. A hold- down mechanism coacts between the frame and the lift arm for normally preventing the lift arm from urging the upward movement of said ramp while permitting downward movement thereof. The ramp is free of positive connection to the lift arm and can thus be swung upwardly, such as due to the normal raising of a truck bed when a load is removed therefrom.
