Crane Wheels are typically mounted on an axle and are designed to roll along the length of the crane runway. They are generally made of steel and are designed to withstand the high loads and stresses generated by the crane and the load being lifted. The wheels are typically grooved to match the profile of the crane runway, which ensures that the crane remains stable and does not derail. The crane wheels are also designed to be easily replaceable, which allows for quick maintenance and repairs.
