Claims8
A support system for supporting a dock leveler, comprising:
- a support leg carrier pivotally attached to the ramp;
- a support leg attached to the support leg carrier and configured to move via the support leg carrier between a ramp supporting position and a retracted position;
- a cam attached to the support leg and biased to a first position;
- and
- a camming surface located below the ramp and positioned to communicate with the cam to guide the cam along the camming surface as the ramp descends, wherein the cam is configured to move to a second position when the ramp descends at or faster than a predetermined speed,
- wherein the support leg retracts when the cam maintains the first position while the cam moves along the camming surface and the support leg maintains the support position when the cam moves to the second position.
