Wheel Assembly Materials
Main Materials
1. Main Beam and Cable Tray Material: High-strength low-alloy structural steel is used, primarily Q355B or Q355D steel, with some heavy-duty models using Q460 high-strength steel. The cable tray and main beam adopt a box-shaped structure design, possessing excellent bending, torsional, and fatigue resistance, capable of withstanding heavy loads and long-term operational wear.
2. Rotating Hanging Beam and Support Beam Material: The main body of the hanging beam is made of high-strength alloy steel, heat-treated to possess good rigidity and deformation resistance, enabling stable rotation; the elastic electromagnetic hanging beam frame uses wear-resistant and impact-resistant steel, ensuring the hanging beam is not easily damaged during frequent rotation and lifting.
3. Lifting and Transmission Component Materials: Core lifting components such as hooks, wire ropes, and chains are made of high-strength alloy steel. The hooks undergo heat treatment, resulting in excellent tensile strength, wear resistance, and impact resistance. Pulleys are made of wear-resistant steel, and bearings are selected for their high temperature resistance and heavy-duty performance, extending the equipment's service life. The core components of the electric hoist and electric winch are made of high-strength wear-resistant materials, ensuring operational stability.
4. Electromagnetic Lifting Devices and Protective Materials: The electromagnets of the electromagnetic lifting beam are made of high-permeability alloy material, ensuring stable and adjustable magnetic force. The equipment surface undergoes shot blasting for rust removal, followed by epoxy zinc-rich primer and polyurethane topcoat treatment, providing excellent corrosion resistance, wind and sand protection, and wear resistance, making it suitable for harsh working environments such as open-air environments and steel mills. Electrical components are selected for their high protection rating, and the casing is made of waterproof and dustproof materials, ensuring stable operation of the electrical system.
