Pedestrian-Vehicle safety systems for loading docks are disclosed. An example system includes a first sensor system to determine a position of a vehicle relative to a pedestrian zone adjacent a dock wall of a loading dock and a second sensor system to monitor the pedestrian zone. The second sensor system to attempt to detect a pedestrian in the pedestrian zone, the second sensor system responsive to signals from the first sensor system to enable the second sensor system to dynamically change a sensing area of the pedestrian zone to maintain a delta threshold between the vehicle and the pedestrian zone in response to the vehicle moving toward a dock wall of the loading dock.

Systems and associated methods for controlling operation of loading dock equipment are disclosed 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 preset sequence of operations. The system can include a display screen that sequentially presents a series of graphical control elements (e.g., touch-sensitive buttons) that enable operation of the loading dock equipment in an appropriate sequence. Additionally, the visual appearance and/or sequence of presentation of the graphical control elements indicate the proper sequence of selection to the user, thereby reducing user confusion and simplifying the operation of the loading dock equipment.

A trailer stabilizing device for stabilizing a parked freight trailer, the trailer stabilizing device comprising a frame separate from the support frame of the parked freight trailer, the stabilizing device frame having mounted thereto wheels and a hitch, the stabilizing device including a repositionable jack.

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.

blocking device (11) for a truck (2) includes at least one height-adjustable blocking arm (24), wherein the at least one blocking arm (24) includes a telescopable plunger (29). The plunger (29) is movable from below the truck (2) against a truck underride guard (5), whereby a rolling-away or driving-away of the truck is prevented.

Methods, apparatus, systems and articles of manufacture are disclosed for sensing RIG positioning and vehicle restraint movement. An example method includes determining a presence of a RIG and enabling a barrier to move to an operational position when the RIG is present.

A wheel immobilization device for preventing unintended movement of a wheel of a mobile object of a type having a wheel includes a rope body that includes a first end and a second end opposite the first end and that has an elongate, pliable, and flexible configuration, the rope body having a plurality of strands twisted together between the first and second ends. The immobilization includes a tail portion situated at the first end of the rope body, the tail portion having a linear configuration and a leader end. The immobilization device includes a retaining portion opposite the tail portion and situated at a second end of the rope body, the retaining portion including a loop that defines a head opening configured and operable to receive the tail portion therethrough.

A repositionable trailer stabilizer for supporting at least a portion of a weight of a parked semi-trailer.

Systems and associated methods for controlling operation of loading dock equipment are disclosed herein.

Additionally, the visual appearance and/or sequence of presentation of the graphical control elements indicate the proper sequence of selection to the user, thereby reducing user confusion and simplifying the operation of the loading dock equipment.

The vehicle leveler 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 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 vehicle leveler also includes opposing side portions which extend the length of and contact the second portion and extension portion, the opposing side portions have a top surface which forms a walkway.
