Abstract
A wheel assembly for movable bolster assemblies adapted to ride on bolster track includes a piston housing vertically oriented above the track. A cylinder piston including a wheel clevis is received within the piston housing. A wheel is rotatably mounted to the clevis and powered by hydraulic pressure to raise or lower the bolster assembly. The cylinder piston is rotatable within the piston housing to allow the axial alignment of the wheel to be changed for orthogonal travel.
