Abstract: An improved maintenance assembly for a dockboard having a ramp and a hinged lip. The maintenance assembly includes a lip locking member which is slidably contained in a bracket attached to the bottom of the ramp. A spring connected to the lip locking member urges the locking member into its stored position. When the lip locking member is extended to engage the bottom of the lip and hold it in an elevated position, the lip locking member engages the lip hinge and pivots slightly to bring a detent into engagement with the bracket and thus lock the lip locking member in its operative position.
