A transport apparatus for transporting heavy objects includes a chassis, which includes at least two side parts and a platform part and rear part between them, a load space arranged in the middle of the chassis, and at least one wheel mounted on each side of the load space of the chassis, with the aid of an axle. The chassis also includes a front part and second side parts, of which the second side parts, the front part, and the rear part together form a frame enclosed on the horizontal plane, inside of which frame is located at least one wheel on each side of the load space, its axle being supported on at least the second side part.

The invention relates to an arrangement in a forestry machine (100), in which arrangement there is a chassis (12), a single-axle set of wheels (13) pivoted to the chassis (12), and at least one auxiliary wheel (18) fitted the outside the set of wheels (13), in order to increase the load-bearing capacity of the rear part (19) of the chassis (12). The arrangement further includes at least one support arm (20) arranged to carry the said auxiliary wheel (18) at its first end (22) and pivoted at its second end (24) to the said chassis (12) with the aid of a transverse shaft (23), a support surface (36) attached to the chassis (12) and a counter surface (38) attached to the said support arm (20), for limiting the transverse movement of the support arm (20). The invention also relates to a corresponding forestry machine.

A truck towing system is described. The truck towing system provides for a first truck to tow a second truck in a back to front relationship, i.e., the front portion of the second truck (the towed truck) is connected or attached to a rear portion of the first truck (the towing truck). The truck towing system includes an upper member to connect with a first truck. A middle member joins the upper member and a lower member in a fixed engagement. The lower member supports a front portion of a second truck. A beam member is engaged to the lower member, and the beam member extends and retracts from an interior of the lower member. The beam member connects to a rear portion of the second truck.

A ride height adjustment of a vehicle traveling along a roadway is controlled by a controller which uses data about overpass clearances and the height of the highest point on the vehicle to lower vehicle height when the height can be lowered sufficiently to avoid collision with an overpass.

A trailer hitch for hitching a trailer to a motor vehicle is disclosed wherein the motor vehicle has a chassis supported by axles suspended from the motor vehicle chassis, the trailer has a chassis supported by one or more axles suspended from the trailer chassis, and the trailer hitch is adapted to hitch the trailer chassis to the motor vehicle chassis for movement therewith and also cause the trailer chassis to help support the motor vehicle chassis to a variable degree via the trailer hitch and in a manner determined by the spring action provided by the trailer axle suspension system(s). And wherein the trailer hitch is also adapted to allow the hitched trailer chassis to turn with respect to the motor vehicle chassis and prevent such turning and to stow a hitched trailer chassis on the motor vehicle.
