Abstract: A frame configuration that is particularly adaptable for use on a trailer such that the frame configuration is operable in both a tilt mode of operation and a dump mode of operation. An actuating mechanism includes a linear actuator that is supported on the frame by a bracket and a yoke that connects to a load bed to power the vertical movement of the load bed in both tilt and dump functions. The linear actuator is pivotally mounted to permit a re-positioning of the actuator into an inoperative position. The frame configuration is provided with an articulated tilt frame in which the tongue is pivoted thereto allowing the load bed to pivot about a tilt axis which can coincide with the wheel axis of the trailer. The bed frame can be locked to the tilt frame for tilting upon articulation with the tongue, while a disconnection of the bed frame from the tilt frame enables the bed frame to pivot about the dump axis to provide a dump function in addition to the tilt function.

Abstract: A tilting trailer suspension which has forwardly disposed, independent swingarms pivotally attached to a trailer main platform and a second u-shaped perimeter frame attached to the rear portion of the swingarms and extending over the swingarms converging at a latching point on the trailer tongue. Each swingarm has a stub axle mounted at its forward end for wheel attachment. A spring is mounted between the forward end of each swingarm and the perimeter frame to provide suspension. Tilting is accomplished by unlatching the u-shaped perimeter frame from the tongue portion of the main frame and raising it so that the swingarms pivot about the connection to the main frame. The rearward end of the trailer platform drops to the ground at a low angle, while the u-shaped perimeter frame assumes an upwardly extending attitude.

Abstract: An improved automatic underride protection actuator for a trailer, the trailer being translatable over a ground surface, includes a rotatable ramp that is shiftable between a ground engaging load/unload disposition when the tiltable bed is in the load/unload disposition and an underride protection disposition when the tiltable bed is in the transport disposition. The ramp underride protection disposition is a disposition in which the ramp depends from a tiltable trailer bed the ramp and is rotatably displaceable from the ramp underride protection disposition by impact oft the ramp with the ground surface, such displacement substantially preventing damage.

Abstract: A rear loading trailer includes a rearward end lowering mechanism to eliminate or reduce unnecessary weighting of the rear wheels and axle during loading or unloading of heavy equipment such as mining earth movers, shovels and the like. The lowering mechanism lowers the rearward end of the trailer and a ramp associated therewith onto a ground surface. With the ramp and trailer end supported at grade, the trailer body and the ground support the weight of the equipment during initial loading/unloading rather than the axles and/or wheels, thereby avoiding possible damage to the wheels and axles. The ramp moves with the trailer end so that trailer lowering would cause the ramp to also lower to the ground.

Abstract: A vehicle carrier which may be used to transport compact automobiles behind motorhomes or other suitable towing vehicles and consists of two primary substructures, a main frame and a trailer bed. The automobile which is to be transported can be loaded on to or unloaded from the carrier by a single person since it is not necessary for him to be inside or in close proximity to the vehicle, nor does he have to step down from the vehicle after it is loaded on to the vehicle carrier. The carrier can be easily moved or rolled by hand and also provides means to reduce the road shock and sway which may be transferred from a vehicle carrier to a towing vehicle.

Abstract: A dolly for lifting one end of a vehicle and for towing the vehicle includes a pair of identical tandem wheel assemblies interconnected by a pair of spaced parallel steel tubes. At least one of the wheel assemblies includes a hydraulic piston which, in spreading one pair of arms on crank members coupled to the wheel assemblies, forces together the second pair of arms. The ends of the spaced parallel steel tubes are coupled into sockets on the ends of the second pair of arms so that their forcing together operates to lift a vehicle whose tires are resting across the steel tubes. The invention includes means for locking the tubes in their raised position and further includes vehicle wheel locking plates that are actuated by the lifting process.

Abstract: A vehicle carrier features a tiltable vehicle bed which, when a vehicle is driven rearwardly on the bed, both tilts upwardly at its front end and slides rearwardly to the ground so that the vehicle can be unloaded, the bed thereby making a less abrupt angle with the ground for facilitating unloading and loading of the vehicle. When a vehicle is driven onto the tilted bed, the latter both tilts downwardly at its front end and slides forwardly. All the foregoing is accomplished automatically by the vehicle itself without the need of any additional form of power to tilt or slide the bed.

A tow bar assembly projects forwardly from the wheel assembly for connection to a standard vehicle tow bar connector.

Abstract: A trailer designed to be towed behind a vehicle with a frame that is slidably attached to the trailer body. Inclined ramps are formed on the members of the frame such that when the frame slides rearward relative to the trailer, rollers on the underside of the trailer body cause the trailer to rotate about the axle. The slidable connection between the trailer and the draw bar yoke is slightly negatively inclined to insure that the mechanism will move freely and to enable the trailer to be returned to the horizontal position by merely applying a forward force on the frame. The invention also employs means to secure the trailer body to the frame when the trailer is in its normal horizontal position.

Abstract: A two-wheeled trailer has a V-shaped hay-bale-holding cradle pivoted about an axis closely above and parallel to the wheel axle. In its bale-loading position, parallel arms of the cradle extend rearwardly from the trailer and close to the ground for sliding under a large cylindrical bale when the trailer is backed-up by a tractor. The then-upright part of the cradle is tiltable forwardly and downwardly into its upright-V bale-carrying position in which it is automatically latched. The trailer is hitch-connected to a tractor by a tow-bar which is longitudinally extendably attached to the trailer chassis. A cable connects the cradle to the front end of the tow bar so that an extending pull thereon (when the wheel brakes are set) causes the cradle to tilt to its latched bale-carrying position. A latch normally holds the tow bar in its slightly extended hauling position.
