CASTER FOR ISOLATING SHOCK AND VIBRATION LOADS

摘要

Three embodiments of a shock-isolating caster (10). A surface-effect damper engages at least one of a wheel element (20) and an intermediate structural member to dampen vibration and shock loads which would otherwise be transmitted from the wheel element (20) through the intermediate structure and mounting member (12) to the equipment supporting cart. A first embodiment positions the damper between an outer wheel rim (25) and an inner wheel hub (24). Second and third embodiments mount the wheel on a pivotable arm and dampen the movement of the arm. Capability to adjust damping levels is provided.
