ABSTRACT:
The invention relates to a retractable double trailing axle attachment that is mounted on an extended frame of a vehicle for increasing the legal load carrying capacity of the vehicle by adding more axles thereto. The retractable double trailing axle attachment includes a pair of generally parallel beams carrying wheels at opposite ends, a pair of arms pivotally connected to the beams and to a support, and pneumatic cylinders and piston rods for effecting movement of the pair of arms from a position at which the beams are generally horizontal to the ground with the wheels engaging the same, and a second nonrunning position in which the arms support the wheels in a superimposed position through the intermediary of a pneumatic air bag.
