Abstract
The present disclosure relates to a vertical hydraulic cylinder axle arrangement that can receive flexible power lines through the cylinder. In particular, a hollow piston rod having a longitudinally extending passage through which hydraulic hoses and electrical lines can pass is incorporated into a heavy-load transporter. A portion of the piston rod defines a splined shaft to mechanically engage a rotating slew gear drive to permit omnidirectional steering. The piston rod extends downward to form a trunnion mount on which drive wheels can articulate laterally to conform to irregularities in various surfaces and other inclinations.
