摘要： A hydraulic system for operating dock levelers, vehicle restraints, and other types of loading dock equipment includes one or more features that prolong the life of the hydraulic fluid. A hydraulic reservoir with a desiccant filled breather cap or a hermetically sealed pliable reservoir minimizes the hydraulic fluid's exposure to condensation and atmospheric moisture. The system can be used for prolonging the life of both biodegradable and- non-biodegradable hydraulic fluids. In some embodiments, the system includes an acceptably biodegradable fluid having a combination of properties that makes the fluid particularly suitable for loading dock equipment.

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 for a truck loading dock includes a pivotal deck that is raised by an inflatable actuator. The actuator includes a pliable upper section that when inflated has a generally vertical cylindrical shape that can provide a heavy deck with substantial columnar support. The actuator also includes a relatively rigid base that is sealingly joined to the pliable upper section such that upper section and the rigid base define an inner chamber of air. A blower for inflating the actuator can be installed inside or outside the actuator. In some embodiments, a valve system reverses the airflow so that the blower can forcibly deflate and compress the actuator up against the bottom of the deck so that the area underneath the actuator can be cleaned.
