A rear collision warning device for trailers that may include one or more sensors, a control circuit, and one or more warning devices. In one aspect, the sensors are configured to monitor a predetermined zone behind a trailer and to optionally trigger warnings as predetermined criteria are satisfied. In another aspect, the control circuit controls the warning devices to emit a warning signal in the form of flashing lights, strobes, audible alarms, and the like, or to send warning notifications to a remote server, an app, or to a cab mounted display. The sensors, circuits, and warning devices are optionally mounted together in a separate housing and mounted at or near the rear of the trailer.

A system includes at least one processor configured to: (i) determining a first distance between a center point of a wheel of an unloaded vehicle and a touch point on a ground surface of a first section of a driving path based on first sensor data of a first set of plurality of image sensors; (ii) determining a second distance between the center point and the touch point on the ground surface of the first section for the loaded vehicle based on second sensor data of the first set of plurality of image sensors; and (iii) based upon a difference between the first distance and the second distance, and characteristics of a respective tire of each wheel, determining a load at each wheel for determining a total mass of the vehicle and a first coordinates of a COG of the vehicle with respect to a front axle of the vehicle.

A spill pallet including: a continuous, unitary, liftable sump-defining base having a bottom, side walls extending from and surrounding the bottom and terminating in an upper edge, a plurality of risers extending from the bottom, and a rim formed in the side walls below the upper edge; and at least one drum-supporting grate that is supportable on the plurality of risers and the rim of the base. Two fork channels that are accessible from a side of the base have a fork cavity height and a fork cavity width sufficient to permit the spill pallet to be lifted by a standard fork lift truck or by a standard pallet jack. The bases are configured such that they are stackable on and partially nestable within identical bases to form stacks, which can be shipped side-by-side as a partial load within a truck, trailer or container.

A system and method are provided for automated engaging of a truck trailer at a loading dock. Sensors measure a distance and an angle of alignment between the incoming trailer and a wall of the loading dock. An outside lighting system guides a truck driver backing the trailer toward the dock door. A vehicle restraint system fixates the trailer within the loading dock in response to signals from the sensors. An overhead dock door opens once the trailer is successfully fixated by the vehicle restraint system. A dock leveler deploys after the overhead dock door opens. An inside dock light indicates to dock personnel that the trailer is ready to be serviced. Once servicing of the trailer is finished, an automated release of the trailer from the loading dock may be initiated by PLC communication.

The utility model discloses a multifunctional trailer and relates to the technical field of fire fighting trailers. The anti-loosening trailer comprises a trailer frame fixedly connected with a U-shaped plate and further comprises an anti-loosening assembly, the anti-loosening assembly comprises a rotating sleeve, the rotating sleeve is rotationally connected with the U-shaped plate, a sliding rod is slidably connected into the rotating sleeve, a plurality of anti-loosening blocks are slidably connected to the rotating sleeve, and lug plates are fixedly connected to the circumferential side face of the sliding rod. When a water hose is loaded, the pull ring is pulled to drive the loosening blocks to move into the rotating sleeve, at the moment, limiting on the gear is released, the gear is rotated to drive the two racks to clamp the water hose on the trailer frame, and after the pull ring is released, the water hose on the trailer frame can be loosened. The springs push the anti-loosening blocks to be inserted into the inserting grooves in the inserting frame, locking of the rotating sleeve is completed, and the situation that the water hose is loosened and falls off due to the fact that fastening is loosened in the transportation and rescue period can be avoided.

A pneumatic brake system for a towing and towed vehicle includes means for supplying a supply pressure and means for supplying a control pressure to the towed vehicle. An electrical connection is provided between respective ECUs on the towing and towed vehicles which are able to exchange information and determine whether the brake system in both towed and towing vehicle is compatible with an electronic brake signal and whether the brake system is compatible with secondary supply pressure being applied via a control pressure line. If both conditions are fulfilled, the brake system actuates a switching device or devices on the towing and towed vehicles to direct air from the means for supplying a control pressure to a second pneumatic supply circuit in the towed vehicle.

Robotic carton loaders or unloaders combine 3D and 2D sensors to detect 3D point clouds and 2D images of carton stacks within transport vehicles such as truck trailers or shipping containers, respectively. Using the 3D point cloud, segments too small to be part of a product such as a carton are discarded to perform edge detection. Segments too large to correspond to a carton are processed by 2D image processing to detect additional edges. The results from 3D and 2D edge detection are transformed in the calibrated 3D space of the material carton loader or unloader to perform one of the loading or unloading of the transport vehicle. Image processing can also detect congestion in the product sequence from individual controllable sections of the conveyor of the robotic carton loader or unloader for individualized unloading.

A lever-type fastening device particularly for the door of the body of trucks, trailers and the like, comprising at least one rod (2), which is supported so that it can rotate along the door (3) and to which at least one lever (4) for opening and closing the door (3) manually is rigidly coupled at right angles, the lever (4) being able to rotate from a position for closing the door (3), in which it engages, by means of a substantially pawl-shaped lug (5), in a respective locator (8) that is rigidly coupled to the body, to a position for opening the door (3), in which the pawl-shaped lug (5) is disengaged from the locator (8), characterized in that it comprises, coaxially to the rod (2), a spring (10) for retaining the lever (4) in the closure position, which is associated with a spacer (11) that allows precision placement of the lever (4) with respect to the door (3) and allows to support the axial load that bears on the spring (10) during operation. <IMAGE>
