Abstract: A transfer system for transferring a transfer body onto a truck. The impetus to move the transfer body is provided by a driver mounted to the truck. The driver may engage a track extending along the transfer body in order to move the transfer body onto the truck. The track may be mounted to a pull bar pivotably secured near one end to the transfer body. The truck may have a dump-truck body with a continuous floor. The pull bar may be pulled underneath the floor as the transfer body is transferred onto the truck whereas the transfer body is pulled onto the floor. A latching system for a transfer module is actuated by a mechanism mounted on the truck and maintains the tailgate of the transfer body closed when remote from a truck. The mechanism may also operate a latching system latching and unlatching a tailgate secured to the body of the truck.

Abstract: An extensible draw bar for facilitating coupling of a towed vehicle to a towing vehicle. An extension may be slidably secured to a static portion of a draw bar. A lock may be secured to the draw bar and be activated and deactivated to fix and release the extension, respectively. An extender may be activated to move the extension outwardly from the static portion. The extension may be slidable with respect to the lock while the lock is activated for certain positions of the extension relative to the lock. The extension may be positionable relative to the activated lock to automatically engage the lock to fix the position of the extension relative to the static portion.
