摘要： Recreation and work-type trailers are difficult to maneuver once detached from the towing vehicle even with the conventional dolley wheel in place. This device includes a horizontal main bar with a pair of plates one at each end being mounted to the underside of the main bar by a bolt and spring loaded to give a limited flexibility thereto. A central socket is pivoted to the upper side of the main bar and receives the stem of the trailer hitch. A handle socket is secured adjacent each end of the main bar also on the upper surface thereof and incline upwardly and outwardly therefrom and selectively receive an elongated handle so that the respective end of the main bar can be elevated by the handle and "walked" forwardly or backwardly or sideways as desired thus maneuvering the trailer readily and easily.

摘要： In a trailer landing gear assembly having a housing secured to a trailer and a foot adapted to engage the ground, attachment means for attaching an extension-retraction assembly to both the housing and the landing gear foot by respectively deforming the landing gear housing and the landing gear foot so that the deformations created support the axial load between the extension-retraction assembly and the landing gear. An axle secured to the downwardly depending end of the extension-retraction assembly is rotatably received in a pair of registering apertures formed in the landing gear foot. Each aperture in the landing gear foot is deformed to form a cylindrical portion coaxial with the aperture and integral with the foot so that the cylindrical portion supports the vertical load between the landing gear foot and the extension-retraction assembly. Similarly a gear base plate forms the attachment means between the upper end of the extension-retraction assembly and the landing gear housing. The gear base plate is received within the housing and includes a flange portion adjacent the interior of the housing. The housing is indented around the flange portion of the gear base plate so that the inward projections formed by the indentations overlap and secure the base plate flange portion to the housing. The projections then function to support the vertical load between the extension-retraction assembly and the landing gear housing.

摘要： A semi-trailer is connected to an agricultural-type tractor by means of a coupling dolly. The coupling dolly has a chassis which is supported by wheels at its rear end and is connected to a weight transfer hitch at its front end. The semi-trailer is connected to the dolly by means of a universal coupling supported between the ends of the dolly chassis and having mutually intersecting rearwardly disposed pitching, rolling and yawing axes. The weight transfer hitch is pivotally connected to the tractor for articulation about a horizontal forwardly disposed pitching axis extending transversely of the tractor, between the axes of the front and rear wheels of the tractor and below the level of the axis of the rear wheels of the tractor. The weight transfer hitch also has bearing means, disposed to the rear of the horizontal forwardly disposed pitching axis, for accommodating rolling and yawing articulation between the dolly and the tractor, the bearing means provided for yawing articulation being disposed on an axis which passes through the bearing means provided for rolling articulation.

摘要： A conventional over-the-road tractor is modified to include a rail car coupling assembly mounting a rail car coupler in tandem behind the conventional fifth wheel for selective movement into and out of the path of conventional trailer coupling movement to permit of selective coupling with a trailer or rail car.When operating in the rail car coupling mode the conventional fifth wheel boom assembly is actuated to effect, via the rail car coupling assembly, a partial weight transfer from the rail car to the traction unit.

摘要： Apparatus and method for attaching a trailer to a tractor truck without the use of a winch. It includes skid means attached to the back end of the truck frame resting on the ground so that the leading edge of the trailer can be pulled up the skids onto the frame and then onto the fifth wheel, where it is locked into position. The means for pulling the trailer up onto the truck frame comprises a pair of chains which are hooked into the rear dual wheels of the tractor and extend backwardly of the tractor parallel to the frame and are attached under the trailer back of the front edge. By moving the tractor forward the chains become wound on the dual wheels of the tractor, pulling the trailer forward up the skids and onto the frame and onto the fifth wheel.
