Abstract: The invention relates to an arrangement for detachable coupling of a trailer equipped with pivoting wheels to a ball hitch of a vehicle. At the forward end of the trailer there is a coupling receptacle to receive the ball hitch and a locking member to lock the ball hitch in the coupling receptacle. In order to prevent the trailer from rotating about a vertical axis through the ball hitch two opposing stops are fitted at the forward end of the trailer at such a distance from each other in the lateral direction that when the trailer is coupled to the ball hitch of the vehicle the stops bear against corresponding opposing stop faces at the rear end of the vehicle.

Abstract: A dump truck or other truck having a rigid chassis and a front and a rear axle assemblies secured at fixed points along the chassis, wherein this truck is distinctively provided with a supplementary axle assembly displaceable behind the conventional rear axle assembly lengthwise of the truck chassis, between a position protracting rearward from the latter to increase the payload rating of the truck and a retracted position under the rear of the chassis for unhindered dumping operation. The supplementary axle assembly is also vertically adjustable between an off-the-ground position for the empty return trips, a normal suspension position for the increased payload rating, and a stiffer suspension position for increased loading on the front axle and steering maneuverability. This truck includes a supplementary frame slidably connected to the chassis, and hydraulic cylinder slidably actuating this frame, and an adjustable suspension interposed between the supplementary axle assembly and frame for the afore-mentioned vertical adjustment.

Abstract: A modular trailer assembly for attachment to a frame of a vehicle includes an elongate support member, a first connector rigidly mountable to the frame of the vehicle, a rear loop, and a second connector. The proximal end of the support member is pivotally connected to the first connector and selectively detachable therefrom. At least one wheel is rotatably connected to the distal end of the rear loop. The second connector includes a first frame member and a second frame member rotatably coupled to one another. The distal end of the first frame is configured to engage the proximal end of the rear loop. The proximal end of the second frame member is configured to engage the distal end of the support member. The first frame member is rotatably moveable to allow cargo to track with the vehicle independently of a change in orientation of the at least one wheel.
