A multi-purpose trailer includes: a trailer frame with a tongue or a gooseneck located at a forward end of the trailer frame and an axle with wheels located adjacent a rearward end of the trailer frame; a pair of slanted arms affixed adjacent the rearward end of the trailer frame; a box pivotally mounted to a distal end of each slanted arm, the box having an upper structural frame and a slanted tailgate; and a pair of movement arms with one end of each movement arm pivotally affixed to the trailer frame and/or adjacent the slanted arm and another end of each movement arm pivotally affixed to the upper structural frame of the box, the movement arms move the box between a load position and a dump position.

A cylinder propping system includes a sleeve and a locking member. The sleeve includes an outer wall that defines an inner cavity and a ledge. The inner cavity is sized to receive at least a portion of a cylinder assembly therein. A first end of the outer wall is configured to hingedly couple to one end of the cylinder assembly. The ledge is spaced apart from the first end. The locking member is sized to engage with the ledge, between the ledge and a cylinder housing of the cylinder assembly, to prevent movement of the cylinder housing in at least one direction along a central axis of the sleeve.

A tip-over prevention system for dumping vehicles includes a tilt detector operably coupled to one of a cargo body and a chassis of a dumping vehicle. At least a portion of the cargo body is configured to be raised by a piston, and the tilt detector is configured to detect a current tilt. The system includes a fluid release valve placed in fluid communication with the piston which is activated in response to the tilt detector detecting a current tilt that exceeds a preset tilt limit. Activation of the fluid release valve releases a pressure in the piston causing the cargo body of the vehicle to lower.

A tailgate overload protection system for a dump truck is disclosed. The tailgate overload protection system comprises a wire and a safety fastener. The wire is configured to interconnect a rear frame and a tailgate arm of the dump truck. The rear frame is connected to the wire via the safety fastener. The safety fastener is configured to break first when a tailgate of the dump truck is overloaded.

A motor vehicle has an automatically controllable rear-tailgate arrangement, which either is comprised of a single pivotable tailgate or a pivotable lower tailgate and a pivotable upper tailgate. An electronic control unit for the motorized control of the pivotable tailgates is associated with the rear-tailgate arrangement assembly. In particular, the control unit is designed to perform the following functionality by an appropriately programmed function module: the control unit evaluates information of a sensor unit for sensing the longitudinal tilt of the motor vehicle; after an opening command by an operating person, the control unit prevents complete opening either of the single rear tailgate or at least of the lower rear tailgate at least in the case of a rearward longitudinal tilt exceeding a defined threshold.

A multi-purpose trailer includes: a trailer frame with a tongue or a gooseneck located at a forward end of the trailer frame and an axle with wheels located adjacent a rearward end of the trailer frame; a pair of slanted arms affixed adjacent the rearward end of the trailer frame; a box pivotally mounted to a distal end of each slanted arm, the box having an upper structural frame and a slanted tailgate; and a pair of movement arms with one end of each movement arm pivotally affixed to the trailer frame and/or adjacent the slanted arm and another end of each movement arm pivotally affixed to the upper structural frame of the box, the movement arms move the box between a load position and a dump position.

A tailgate support is arranged in a sealing channel between an inner panel of the lid bodyshell and a lateral covering of the rear lights.

A machine includes a chassis and an object detection sensor alignment monitoring system. The monitoring system includes a first sensor module coupled to an object detection sensor. The first sensor module measures values of object detection sensor pitch, roll, and yaw. The monitoring system also includes a second sensor module coupled to the chassis. The second sensor module measures values of chassis pitch, roll, and yaw. The monitoring system further includes a control unit. The control unit compares the measured values of the object detection sensor and chassis pitch, roll, and yaw. The control unit determines whether the measured values are within a predefined tolerance. Further, the control unit generates an alert if the measured values of the object detection sensor and chassis pitch, roll, and yaw are beyond the predefined tolerance.
