A dock leveler has a support with a deck pivotally secured to the support at one end for movement between a stored position and an elevated position. A deck lip is pivotally connected to the deck assembly for movement between a pendant stored position and a bridging position projecting from said deck assembly. A lift mechanism acts on said deck assembly to lift it toward the elevated position and a lip operating mechanism operatively connected to the lip moves it from the pendant position to the bridging position. A latch holds the lip in the bridging position. The latch releases the lip upon relative movement between the lip and the deck assembly and has a yieldable connection to permit limited pivotal movement between said lip and said deck assembly upon application of a rearward force from a vehicle to allow the lip to move to an unlatched position.
A dock leveler comprising a support a deck pivotally secured to said support at one end for movement between a stored position and an elevated position, a deck lip pivotally connected to said deck assembly at an opposite end to said one end for movement between a pendent stored position and a bridging position projecting from said deck assembly, a lift mechanism acting on said deck assembly to lift it toward said elevated position, a lip operating mechanism operatively connected to said lip to move it from said pendant position to said bridging position upon attainment of said elevated position, and a latch to hold said lip in said bridging position, said latch releasing said lip upon relative movement between said lip and said deck assembly and having a yieldable connection to permit limited pivotal movement between said lip and said deck assembly upon application of a force thereto.
A dock leveler comprising a support frame, a deck assembly pivotally secured to said frame at one end for movement between a stored position and an elevated position, a deck lip pivotally connected to said deck assembly at an opposite end to said one end for movement between a pendant stored position and a bridging position projecting from said deck, a lift mechanism acting on said deck to bias it toward said elevated position, a lip operating mechanism operatively connected to said lip to move it from said pendant position to said bridging position upon attainment of said elevated position and including a first tensile member acting between said support frame and said lip to initiate movement from said pendant position as said deck assembly approaches said elevated position, and a latch to hold said lip in said bridging position, said latch being moveable from an inactive position to an active position in which said latch acts upon said lip as said deck assembly approaches said elevated position, said latch having a yieldable connection to permit limited pivotal movement between said lip and said deck assembly upon application of a force thereto.
