Crane Trolley Wheels

Crane wheels are the most important parts in crane traveling system which are also the most vulnerable crane parts due to the friction between crane wheelsThe trolley is the mechanism that moves the hoist along the bridge girder of a crane. The hoist is moved horizontally along the top or underside of the bridge girder to position it above a loadFor most crane wheels, medium-carbon steel is the most commonly employed material, due to its wide availability and lower cost.An RT crane typically has a hydraulic boom, four tires, two axles, and features four-wheel drive and all-wheel steering, increasing maneuverability for off-road operations.Unlike gantry and bridge cranes, monorail cranes do not have a bridge or girders. The trolley connects to an I beam that is built into the ceiling and travels along the flat surface at the bottom of the beam. Material runs in a straight line along the beam being carried by the hoist and moved by the trolley.
