ABSTRACT:
A trailer for elongated loads, especially for torsionally-sensitive loads, such as a crane boom, consists of a channel cross-section body having a plurality of wheels at each side to the rear. Each wheel is independently mounted on the trailer frame by a cranked arm pivoted to the frame and carrying the wheel on a stub axle. Normal road shocks are accommodated by helical compression springs mounted around the piston rod of a respective cylinder and piston assembly mounted above the wheel between the arm and the trailer frame, the assembly permitting the height of the trailer frame above the ground to be adjusted. The cylinders of each plurality are connected to one another for equalization and all of the cylinders are connected together for slow travel over rough terrain so that the trailer stays relatively level if any one wheel encounters an obstacle. For rapid travel on smooth roads the cylinders of one plurality are isolated from those of the other plurality by a valve in the hydraulic supply system. The front end of the trailer is provided with a vertically adjustable cross-bar having coarse and fine vertical adjustment.
