Disclosed is a hydraulic buffer energy storage device for an over-discharged hoist skip in a vertical shaft. The hydraulic buffer energy storage device for an over-discharged hoist skip in a vertical shaft comprises a vertical shaft, where a hoist skip is hung on an inner side of the vertical shaft, and a hydraulic buffer mechanism is arranged on the inner side of the vertical shaft; the hoist skip is positioned above the hydraulic buffer mechanism; the hydraulic buffer mechanism is communicated with an accumulator group, a pressure relief part and an oil replenishing part through an oil pipeline; the accumulator group is communicated with an energy storage part through an oil pipeline; the energy storage part, the pressure relief part and the oil replenishing part are respectively communicated with an oil tank through oil pipelines, the hydraulic buffer mechanism is connected with a displacement sensor.

A cargo vehicle includes a cargo area configured to receive a load of cargo for transport, and a plurality of wheels configured to support the cargo area above a road surface while the plurality of wheels roll along the road surface. A rear structure of the cargo vehicle includes a rear cross member located at a rear edge of the cargo area, and a first light array is located in the rear cross member. A first dock bumper is placed directly over a first lamp of the first light array on a first lateral side of the rear cross member, the first dock bumper including a through hole accommodating the first lamp to visually mark a first outboard edge of the cargo vehicle.

The present invention is a dock seal system for mounting on a structure wall. The system includes at least one side seal made up of a backer board having a hollow configuration and a foam seal attached to the backer board. A first side of at least one wear pleat is removably connected to the foam seal by at least one pleat fastener. This allows rapid, easy replacement of worn-out wear pleats.

An impact buffer has a retaining part for fitting to a loading ramp, a stop part for a vehicle to be loaded at the loading ramp to strike, and a buffer part for cushioning the stop part against the retaining part. The stop part is supported on the retaining part with at least one pivot lever.

There is provided herein an endoscope assembly comprising at least one front-pointing viewing element on a front end of a distal section of the endoscope assembly, at least one side-looking viewing element on at least one side wall of the distal section of the endoscope assembly, a working channel configured for insertion of a medical tool towards the distal section, and a system for regulating the direction of exit of medical device wherein said system enables the medical device to exit at multiple angles to the long dimension of the endoscope device either from the front end or through side walls of the distal section of the device.

Bumpers for use at loading docks are disclosed. An example bumper includes a housing defining a lip-engaging surface to engage a lip of a deck when the lip is in a retracted position, and a RIG-engaging surface positioned adjacent the lip-engaging surface. The RIG-engaging is movable relative to the lip-engaging surface. The RIG-engaging surface is to move relative to the lip-engaging surface when a RIG of a vehicle imparts a force to the RIG-engaging surface when the vehicle is at a loading dock.

Systems and methods for automatically controlling loading dock equipment, such as in response to a trailer approaching and docking at a docking station, are disclosed. The systems and methods can provide scanning devices and scanning operations which assist with, for example, properly aligning a trailer at a docking station and/or checking an interior area in front of the dock door for obstructions. The systems and methods can also transmit messages between components of the system and/or to users of the system regarding the status of components of the systems and/or the status of the overall docking process.
