Wheel Assembly Materials
Main Material Specifications
1. Main Structure (Cable Tray, Main Beam, End Beam): The core is made of high-quality carbon structural steel (mostly Q235B or Q355B), welded and aged, possessing high strength, high rigidity, and good load-bearing capacity, ensuring stable operation and resisting corrosion in complex environments.
2. Lifting Gear Components: The hook is forged from high-strength alloy steel, heat-treated for enhanced hardness, toughness, and load-bearing capacity. The accompanying electromagnetic chuck, grab bucket, and other specialized lifting gear utilize high-strength steel and wear-resistant alloys as core materials, adaptable to various material lifting needs.
3. Traveling Mechanism Components: The wheels of the trolley and crane traveling mechanisms are made of forged steel (commonly 65Mn or 42CrMo), quenched and tempered for high hardness and wear resistance. Gears, shafts, and other transmission components are made of heat-treated alloy steel, ensuring high mechanical efficiency and long service life.
4. Electrical and Safety Components: Controllers, cables, contactors, and other components of the electrical equipment are made of high-quality dustproof, moisture-proof, and high-temperature resistant electrical materials, suitable for complex working environments. Overload limiters, protection devices, and other core components utilize high-precision, high-reliability metal and electrical materials to ensure stable safety protection functions.
5. Auxiliary components: The outer shell of the operating room is made of high-quality steel plate and can be insulated and sealed according to the type; the connectors and fasteners are made of high-strength carbon steel or stainless steel, which is rust-proof and corrosion-resistant, ensuring that all components are firmly connected and improving the overall stability of the equipment.
