Abstract: A hydraulically operated dock leveler having a single cylinder that raises the ramp and extends the lip. The leveler includes a ramp assembly that is hinged at its rear edge to a supporting structure and a lip that is hinged to the forward edge and can be pivoted between a downwardly hanging pendant position and an extended position. A lip extension crank is attached to the forward hinge and a hydraulic cylinder is interposed between the crank and the supporting structure. The hydraulic system includes a pump to provide fluid to the cylinder at the desired pressure to raise the ramp and extend the lip. By operating the cylinder, the ramp assembly rises from a horizontal cross traffic position to an upwardly inclined position. As the ramp nears the top of its inclined position the extension crank is actuated downward allowing the hydraulic cylinder to rotate the crank about the hinge and extend the lip. When operation of the pump is discontinued, the ramp will descend until the lip engages the bed of a truck.

Abstract: The present invention pertains to a mechanically actuated dock leveler with a mounting frame secured in a pit of a loading dock, and a deck assembly with a deck and extendable lip. A deck lift assembly biases the deck to move from a parked position to a raised position to activate a lip extension assembly. As the deck is “walked down”, the lip is extended and the lip extension assembly is deactivated in a controlled manner so that the deck and lip reach an engaged position against the trailer and are kept in place by a hold down mechanism. The deck assembly has a float housing with a slot for releasably engaging the lift assembly to achieve a range of float positions where the deck and lip rest on and float with the trailer as it is loaded and unloaded. The deck assembly has a durable combined lip lug and header plate hinge construction.

Abstract: A tilt carriage assembly including a base frame and a carriage pivotally supported by the base frame. The carriage includes a bottom member adapted to support a container and a back member positioned above the bottom member. A manual locking mechanism is operatively positioned between the carriage and the base frame, and includes a lock control member positioned adjacent the back member. The lock control member is movable between a locked position where the carriage is secured relative to the base frame and an unlocked position. A step member is secured to and extends laterally outwardly from the carriage, the step member being engageable by a user's foot to facilitate tilting of the carriage. A side member is positioned above at least one of the side portions of the bottom member, and includes a beveled edge that facilitates loading a container onto the carriage. A conveyor device is secured to the bottom member for facilitating motion of a container relative to the bottom member.
