    摘要： A closed loop reciprocating fluid circuit apparatus (150) for mechanically powered and electromechanically powered dock levelers (100), which may be mounted at a forward edge of a dock leveler to selectively engage the dock leveler during pivotal downward movement of a deck, is provided. The apparatus may include a header (158) extending from a fluid chamber (152) (e.g., a hydraulic cylinder), where the header may selectively engage the deck, within the range of dock leveler heights, including below dock level and above dock level operating positions. The hydraulic cylinder may be vertically oriented and coupled to a fluid accumulation chamber (156), such that vertical movement of the header in response to the deck's downward movement causes fluid displacement into the accumulation chamber. That displacement may be in a horizontally oriented fluid chamber having a piston that reacts to the fluid transfer. Alternatively, that displacement may be into a resilient fluid chamber such as a bladder (504) housed within a suitable container, or a fluid chamber (404) such as a fluid reservoir with a breather (410), for air volume compensation. The hydraulic cylinder and header may be urged to the extended position, for example by extension springs (308) acting on a piston within the fluid accumulation chamber, or by a pull chain or latch (420) coupled to the cylinder and the upward movement of the deck. A flow control valve (304), e.g., a velocity fuse or solenoid valve, is connected between the cylinder and the fluid accumulation chamber to respond to free fall of the deck. Resetting to normal operation after free fall detection may occur after load removal from the deck and by movement of the cylinder to the opposite direction or by electrical control input to the control valve.

    摘要： A dock leveler (12) includes a vehicle-engaging pivotal lip (26) extending from the front end (22) of a pivotal deck (16), wherein the lip has one or more unique features that provide a smooth transition for forklifts traveling between the lip and a trailer bed (14) upon which the lip is resting. The smooth transition minimizes jolting and vibration of the forklift and its driver as the forklift wheels pass over the leading edge of the lip. The special features of the lip may include one or more of the following: a curved traffic-bearing surface (42,60,84) terminating at a sharp or blunt leading edge (34 a-g), a traffic-bearing surface (70) that includes both flat (50,72) and curved (74) sections, a multifaceted traffic-bearing surface (62) that approximates a curved surface, a rubber or plastic shock absorbing element, (78,86,114), an articulated nose piece (98) at the lip's leading edge, and a main lip plate (106,116) that is coplanar with the deck's traffic surface (36) (i.e., zero crown angle).

    摘要： A system and method for remotely controlling loading dock components is disclosed that includes a distribution center having at least one dock station for exchanging materials and a dock component configured to in at least two operational states. An actuator is included that is configured to change the operational state of the dock component in response to an activation signal. A mobile remote control is configured to generate the activation signal to cause the actuator to change the operational state of the dock component and at least one predefined non-activation zone is included such that changing of operational state of the dock component is inhibited when the mobile remote control is located within the at least one predefined non-activation zone.
