A system and method for operation of an autonomous vehicle (AV) yard truck is provided. A processor facilitates autonomous movement of the AV yard truck, and connection to and disconnection from trailers. A plurality of sensors are interconnected with the processor that sense terrain/objects and assist in automatically connecting/disconnecting trailers. A server, interconnected, wirelessly with the processor, that tracks movement of the truck around and determines locations for trailer connection and disconnection. A door station unlatches/opens rear doors of the trailer when adjacent thereto, securing them in an opened position via clamps, etc. The system computes a height of the trailer, and/or if landing gear of the trailer is on the ground and interoperates with the fifth wheel to change height, and whether docking is safe, allowing a user to take manual control, and optimum charge time(s). Reversing sensors/safety, automated chocking, and intermodal container organization are also provided.

The wheel chock (100) is designed to prevent a vehicle (104) from moving in an unauthorized or accidental manner. The wheel chock (100) includes a longitudinal extension (200) to further improve resistance to rollover and tipping when the wheel (102) is pressed forcefully against the wheel chock (100). The extension (200) includes a protruding portion (210) that can extend over a relatively long distance along the tire sidewall (126) and allows the wheel chock (100) to create a latching engagement between a tooth (160) and a blocking element (112) on the base plate (110) beyond the front end of its main body (150).

The present invention relates to a system for preventing semitrailer collisions with a loading ramp. The system comprises a sensor unit network, and a guide block.

A slurry handling apparatus includes at least one reception hopper includes a base, a rear wall and opposing side walls, and an opening provided in the base. Slurry delivered into the reception hopper from a tanker can pass through the opening in the base, and a respective first dewatering screen having an apertured screening deck is located beneath the at least one reception hopper so that slurry passing through the opening is delivered onto the deck of the respective screen, with undersize material and water passing through the apertures of the deck to be received within a sump, and with oversize material passing over the deck to be discharged from a downstream end of the deck.

Example vehicle restraint systems and related methods are disclosed. An example vehicle restraint system includes a wheel chock having an inclined tire-engaging surface, where the wheel chock is movable to an installed position at which the wheel chock is to engage the freight transporter. The vehicle restraint system includes a take-up reel and a retractable elongate member to be at least partially wrapped around the take-up reel. The retractable elongate member to extend between the wheel chock and a platform structure.

Systems and associated methods for controlling operation of loading dock equipment are described herein. In some embodiments, the system and associated methods can be used to control operation of loading dock equipment (e.g., a vehicle restraint, a dock door, a dock leveler, etc.) according to a sequence of operations. The sequence of operations can include different sub-sequences based on loading dock conditions. The system can include a display screen that sequentially presents a series of control elements that enable operation of the loading dock equipment. Additionally, the visual appearance and/or sequence of presentation of the control elements indicate the proper sequence of selection to the user, thereby reducing user confusion and simplifying the operation of the loading dock equipment. Some functionality of the control panel can be enabled or disabled based on a current level of authorization.

The device includes a first portion which has a leading edge and a trailing edge, the trailing edge is disposed further from the driveway than the leading edge. The embodiment also includes a second portion which has a leading edge and a trailing edge, the leading edge of the second portion is removably attached to the trailing edge of the first portion and the leading edge of the second portion is disposed further from the driveway than the trailing edge of the second portion. The second portion also includes an extension portion. The first portion and second portion are separate from each other until they are removably attached by a connection apparatus. The device also includes at least one wheel chock with a corresponding wheel-chock track.

A vehicle leveler which includes a first portion with a leading edge and a trailing edge, the trailing edge is disposed further from the driveway than the leading edge. The leveler also includes a second portion with a leading edge and a trailing edge, the leading edge of the second portion is disposed further from the driveway than the trailing edge of the second portion. The vehicle leveler has a door interlock system with at least one pair of photoelectric sensors with a sensor path. When a vehicle is being loaded or unloaded on the vehicle leveler, and at least one of the vehicle doors is opened, the door blocks the sensor path of the photoelectric sensors and prevents the vehicle leveler from lowering or raising.
