Abstract
A storage and retrieval machine comprising a mast having a generally vertical outer surface, a carriage movable vertically along the mast, a bearing assembly including a wheel which is rotatably supported by the carriage, which rolls along the mast surface, and which is movable relative to the carriage in the direction perpendicular to the mast surface, a pad of low-friction material mounted on the carriage, and a spring biasing the wheel toward the mast surface such that the pad is normally spaced from the mast surface and such that the wheel moves relative to the carriage so that the pad engages the mast surface when the force exerted on the wheel by the mast surface exceeds a predetermined amount, and a shuttle supported by the carriage for horizontal movement relative thereto.
