ABSTRACT:
A vertically-sprung idler wheel of a lift truck is journaled near the outer end of an arm pivotally mounted for limited rotation about a substantially horizontal longitudinal axis, and spring means are provided to oppose rotation of the arm. The idler wheel may be linkage-steered or instead comprise a self-steered caster wheel. The assembly requires less space.
