  • Dock levelers and associated systems and methods
    Patent number: 8407842
    Abstract: Dock levelers, such as mechanical dock levelers, are described herein. In one embodiment, a mechanical dock leveler includes a ramp having a lip pivotally attached to a forward edge. A ramp lifting system is configured to assist upward rotation of the ramp as it is manually raised. In this embodiment, a lip lifting system is operably coupled to the ramp lifting system so that the ramp is initially “downward biased” prior to being raised, and then becomes at least partially supported in a raised position by the lip lifting mechanism, once the lip lifting mechanism is engaged.
