A drive arrangement for adjusting a flap, in particular a tailgate, of a motor vehicle, which in the mounted state is mounted on a body of the motor vehicle so as to be pivotable about a flap pivot axis and which can be adjusted between an open position and a closed position over a pivot angle. It is proposed that the drive arrangement comprises a torsion spring arrangement having a torsion spring, the torsion spring being adapted to generate a torsional torque about a torsion axis, that the torsion axis is arranged with an offset to the flap pivot axis, and that the drive arrangement comprises a first gear unit which converts the torsional torque into a supporting force or torque acting on the flap in the direction of the closed position or in the direction of the open position thereof.

A refuse hopper is disclosed which may be mounted in the bed of a pick-up truck, a flat-bed truck or on a trailer. The refuse hopper includes a horizontally disposed support frame having a rear end, a front end, a first side and a second side. A hopper is pivotally mounted on the support frame and has a front end, a rear end, a front side and a second side. The refuse hopper is selectively movable between a horizontally disposed loading position and a dumping position. A compactor plate is pivotally mounted to the hopper and is movable between an upwardly extending loading position to a refuse packing position within the hopper. The hopper has a volume of about four cubic yards.

Another implementation of the present disclosure is a refuse vehicle. The refuse vehicle includes a chassis, a body coupled with the chassis, a tailgate, an electric lock, and a fully electric tailgate actuator assembly. The body assembly defines a refuse compartment. The tailgate is coupled with a rear of the body and is transitionable between a first position to limit access to the refuse compartment and a second position to allow access to the refuse compartment. The electric lock is operable between an engaged state and a disengaged state to limit movement of the tailgate out of the first position when the electric lock is in the engaged state. The fully electric tailgate actuator assembly is configured to transition the tailgate between the first position and the second position.

A system and a method for providing an opening for delivering a shipment into a loading space of a vehicle, as well as a corresponding vehicle and a method for delivering a shipment into a vehicle, include a controller arranged and configured to calculate a first length of the opening based on received and/or determined dimensions of the shipment and further based on an area of the opening configured to receive the shipment through the opening in the loading space of the vehicle. An actuator is arranged and configured to move a first element of the vehicle relative to a second element of the vehicle by the calculated first length of the opening in order to provide the exactly necessary opening.

A dumping system for accurate and precise dumping of ballast rock, sand, and gravel (aggregate) to all areas of a railroad track (a track), all areas of a roadway, and all regions of the roadway is described. The dumping system includes a dump box, a dump gate having at least two delivery gates, an operating system, and a control system. The at least two delivery gates of the dump gate each include a top portion and a bottom portion. The bottom portion of each of the at least two delivery gates is adjusted in real time by the operating system via the control system to accurately and precisely deliver the aggregate to all areas of the track or roadway. The dump box may further be rotated horizontally and vertically to aid with the delivery of aggregate to the track or roadway in an accurate manner.

A rotatable tailgate assembly is provided for installation on a dump bed. The tailgate assembly has support members attachable to the side of the dump bed. Each support member has at least one bearing adjacent at a free end extending rearwardly of the dump bed's rear opening. A tailgate has a cylindrical tailgate shaft with a first end rotatably received within the bearing of a first support member and a second end rotatably received within a bearing of a second support member. The tailgate has a closure portion extending radially away from the tailgate shaft. The closure portion engages the rear edges of the dump bed floor and sides to close off the dump bed opening when the tailgate assembly is in a closed rotational position. The tailgate assembly also comprises a rotation actuator operatively connected to the tailgate shaft for selective rotation thereof.

A monitoring system and method for a vehicle with a dump body has at least four sensors on the vehicle one to monitor the position of the dump body relative to a discharge end, one to monitor the position of a gate at the discharge end, one to monitor gate locks, and one to monitor a speed and direction of the vehicle. The sensors are arranged to provide an output signal to a display which includes a programmable controller and software to provide a warning signal to the display for any unsafe conditions.
