Abstract

The dock leveler is adapted to be mounted to a loading dock and includes a ramp, a guard, and a biasing member. The ramp is rotatably coupled to the loading dock and the guard is rotatably coupled to the ramp. The guard is rotated between a raised position that forms a barrier and a lowered position that permits loading equipment to freely pass. The biasing member is coupled to the guard and biases the guard toward the raised position when the guard is in the raised position and biases the guard toward the lowered position when the guard is in the lowered position.
