The present invention comprises a weight distribution tag trailer, having at least some of the following features: (a) a frame assembly, including beams and cross beams and side axle beams, (b) an axle coupled to the frame assembly, (c) shims for optional position between an axle assembly and the side axle beams to allow adjustment of load and balance (d) at least two wheels rotatably mounted to the axle, wherein at least one beam includes an end complementarily sized to be received by a vehicle receiver hitch assembly, and at least one other beam includes a clamp for coupling the beam to a cross frame of the vehicle receiver hitch.

A vehicle front-end assembly includes a vehicle frame, a first tow hook and a skid plate. The vehicle frame has a first front side member with a front-end portion. The first tow hook is attached to a downward facing surface of the first front side member. The skid plate has a main section, a first attachment flange extending from a first lateral side of the main section. The first attachment flange overlays a portion of the first tow hook and is attached to the downward facing surface of the first front side member such that the main section covers a central forward area of an underside of the vehicle.

A connector device for connecting a first vehicle to a second vehicle, the connector device comprising an upper frame and a lower frame, where the rear side of the upper frame is configured to pivotally connect to the front upper side of the second vehicle, about a first rotation axis, and the rear side of the lower frame is configured to pivotally connect to the front lower side of the second vehicle, about a second rotation axis that is angular in respect to the first rotation axis. The non-zero angle formed between the rotation axes restricts the rotation movements at least about one of these axes. The connector device can be used for forming a removable chain of main and towed vehicle(s) in a manner that enables folding of a towed vehicle over the first vehicle and removably connecting as many vehicles to be towed as required.

Methods and apparatus are disclosed for a three-point attachment trailer hitch. An example hitch includes a crossbar including a first end and a second end, the first end or the second end including at least one tab protruding from an edge of the first end or the second end, and a first endplate positioned on the first end or the second end of the crossbar using the at least one tab, the endplate including a first threaded hole and a second threaded hole, a diameter of the second threaded hole larger than a diameter of the first threaded hole.

A load-bearing trailer dolly which connects a tongue-type boat, utility or other trailer to a towing tandem trailer and bears weight from the trailer during towing. In a preferred embodiment, the trailer dolly is characterized by an axle mounted on a pair of wheels. A dolly frame height-adjustable trailer hitch centered coaxial above the axle axis and midway point framed dolly plate mount by operation of an adjustable sleeve reducer fastened by pinning and lock. Includes dual connecting adjustable height tongues for attachment to rear end trailer hitches on the tandem towing trailer at which a pair of hitch fasteners for engaging the trailer dolly tongues are attached to the rear of the tandem trailer. The adjustable tongue hitches on trailer dolly will give ability to horizontal level tandem dolly. A shock-absorbing spring is fitted between the axle mount and the dolly frame for cushioning the dolly frame on the axle mount as the trailer is towed behind the towing tandem trailer. In the industry of dollies, the car dolly has no shock-absorbing function, just square axle with hubs for wheels, axle is attached to car dolly frame. There is an option with shock-absorbing mechanism or s non shock-absorbing option.

The present invention comprises a weight distribution tag trailer, having at least some of the following features: (a) a frame assembly, including beams and cross beams and side axle beams, (b) an axle coupled to the frame assembly, (c) shims for optional position between an axle assembly and the side axle beams to allow adjustment of load and balance (d) at least two wheels rotatably mounted to the axle, wherein at least one beam includes an end complementarily sized to be received by a vehicle receiver hitch assembly, and at least one other beam includes a clamp for coupling the beam to a cross frame of the vehicle receiver hitch.

The invention concerns a coupling device (14) for articulated connection of two elements (12) of a device (10) for conveying and/or sorting piece goods, wherein the coupling device (10) connects together an end (24, 26) of each of the two elements (12) pivotably with respect to a rotational axis (20) in a plane to both sides (24, 26), and the two ends (24, 26) lie diametrically opposite each other in a neutral position.

It is provided that the coupling device (14) is configured such that, starting from a respective central axis (28) of the two ends (24, 26), the rotational axis (20) on a pivot movement in the direction of the one side (24) lies on this one side (24) of the central axes (28), and on a pivot movement in the direction of the other side (26) lies on this other side (26) of the respective central axis (28).

The invention furthermore concerns a corresponding device (10) for conveying and/or sorting piece goods.
