摘要： A hauling system for loose bulk material at a construction site uses a self-propelled vehicle and a trailer that is not self-propelled which are releasably connected by a system that is operable by a single operator who aligns, connects, locks, unlocks and disconnects the self-propelled vehicle and the trailer, preferably without leaving the cab of the self-propelled vehicle. A hook secured on a tool of the self-propelled vehicle and a ring secured, directly or indirectly, to the trailer, releasably connect them. Rotation of the tool, e.g. the bucket of a wheel loader, locks and unlocks the coupling. The operator of the self-propelled vehicle has direct visible sight of the coupling. The ring can be mounted at the end of an articulated frame pivotally connected to a hydraulic jack cylinder. A dump body of the trailer can be raised by a hoist piston. Vertical reciprocation of the tool pumps the jack cylinder which produces hydraulic power to activate the hoist cylinder via a valve body. In another form the trailer mounts a track at its front end which is curved to cam the trailer up at its front end when a moveable carriage is driven along the track by the wheel loader via hook and ring couplers. A lock pin on the carriage secures it for connection and travel.
