A support arm for a loading bunk of a transport vehicle, having a horizontal and a vertical section, each section comprising an inner and outer segment, which are telescopically connected to each other so that the length of the vertical and horizontal sections is variable. Each section further comprising an inner hydraulic actuator with at least one hydraulic pressure chamber, connected to the segments of the horizontal and vertical sections so that movement of the hydraulic actuators changes the lengths of the vertical and horizontal sections respectively. The vertical section being fixedly connected to the horizontal section on one end of the inner or outer segment.

A deck plate assembly for a truck chassis having first and second elongated frame members. Elongated rail brackets are mounted on the upper ends of the first and second frame members. Each of the rail brackets has an elongated slide slot formed in the inner sides thereof. A storage box and an airline box are positioned between the first and second frame members. A storage box support frame is slidably mounted in the slide slots of the rail brackets so as to be positioned over the storage box. The storage box is bolted to the storage box support frame. An airline box support is slidably mounted in the slide slots of the rail brackets so as to be positioned over the airline box. The airline box is bolted to the airline box support. Metal deck sections may also be slidably mounted in the rail brackets.

A vehicle for transporting cargo has a deck and a group of cradles. Each cradle in the group is pivotable relative to the deck between an extended configuration in which the cradles extend at a transverse angle relative to the deck, and a collapsed configuration in which the cradles are substantially flush with the deck. The vehicle has an actuator adapted to concurrently pivot two or more cradles in the group between the extended configuration and the collapsed configuration.

Method and apparatus for an extendable logging trailer constructed of left and right main I-beam members having left and right male telescoping beams moving on rollers on the bottom inner flange of the main I-beam members. The male telescoping beams allow the trailer to be retractable or extendable so that it can assist in offloading the logs/pipes from the logging trailer. In operation, a front bolster and push rack are moved in unison by a first hydraulic cylinder toward the rear of the trailer at the same time as a rear bolster is moved by a second hydraulic cylinder toward the front of the trailer thereby causing the length of the trailer to shorten. As the trailer shortens, the logs/pipes which are carried on the bolsters are forced toward the rear of the trailer so that gravity eventually causes the rear ends of the logs/pipes to fall downwardly toward the ground which allows the operator of the tractor which is pulling the logging trailer to move the logging trailer forwardly causing the logs/pipes to become completely offloaded from the logging trailer.
