Crane wheels are suitable for bridge cranes, gantry cranes, casting cranes, box cranes, slab handling cranes, steel coil clamp cranes, electromagnetic cranes, etc. in metallurgical plants. As a key load-bearing and moving component, the performance characteristics of crane wheels directly affect the operating efficiency, safety and life of the crane. The following are its main performance characteristics and detailed descriptions:
High load-bearing capacity
Features: Able to withstand the deadweight, rated load and dynamic impact load of the crane.
Implementation: Use high-strength materials (such as alloy steel ZG55, ZG42CrMo, etc.), and improve hardness and toughness through heat treatment (quenching + tempering).
Standard reference: Usually in accordance with ISO 4306 or FEM standards, the load capacity must match the crane working level (such as A3-A8).
Excellent wear resistance
Features: Resist rail friction and rolling contact fatigue, and extend service life.
Technical measures:
The hardness of the wheel tread reaches HB300-400 (HRC45-55 after quenching).
Use special processes (such as surface high-frequency quenching and carburizing treatment) to enhance the wear resistance of the surface.
Influencing factors: Track material matching (such as QU70/QU100 rails), working environment (dust, humidity).
Good fatigue resistance
Features: Withstand repeated alternating loads without breaking or peeling.
Design points: Optimize the wheel rim geometry (such as arc transition), no internal defects (detected by ultrasonic flaw detection).
Material selection: low alloy steel or forged steel, fatigue strength must meet more than 10^7 cycles.
Wide range of use scenarios
Features: It can adapt to various complex working conditions and is widely used in lifting equipment in different fields.
High load-bearing and impact resistance, high temperature resistance, corrosion resistance, fatigue resistance, and vibration resistance. It can be used for port container cranes, metallurgical casting cranes, mining open-pit cranes, nuclear power special cranes, and indoor workshop bridge cranes.
