Abstract

A crane wheel is adjustably mounted in the web structure of a crane carriage, head carrier, or the like by a bearing holders on each side of the wheel. The bearing holders are individually, pivotably fixed to the web structure by aligned clamping sleeves above axle. Two pendulum-type bearings in the necks of the holders journal the wheel axle. Adjusting screws mounted on the carriage abut cam stops on the bearing holders to adjustably fix the orientation of the wheel axles, including the plane of rotation of the wheel.
