Nippon Sharyo DH508 Crane Sprocket – Heavy-Duty Drive Tumbler Replacement
Product Specifications
Product Description
The crane sprocket (also known as the drive tumbler) is a critical power-transmitting component engineered specifically for tracked crawler cranes and piling rigs. Its core function is to engage directly with the track links, converting the rotational hydraulic power from the travel motor into linear mechanical thrust. By meshing precisely with the track pins, a high-quality drive sprocket ensures smooth propulsion, prevents track misplacement, and maintains stable traction on tough foundation job sites.
Key Features & Technical Advantages
High-Strength Material Construction: We utilize premium 50Mn structural alloy steel. This guarantees exceptional impact toughness and structural load-bearing capacity under extreme dynamic pressures.
Advanced Induction Hardening: The sprocket teeth undergo precise CNC induction quenching. This deep-hardened surface provides superior abrasion resistance, significantly reducing wear against track link pins.
Anti-Corrosive Surface Finish: Treated with a professional-grade anti-rust marine coating to withstand harsh mud, salt water, and highly corrosive mining environments.
Full OEM Customization Support: We offer tailored engineering solutions, including custom brand logo casting, specialized appearance paints, and dimensional adjustment to fit worn chassis.
Standard Export Packaging
All ShunQi crawler parts are securely packed on standard export, fumigation-free plywood pallets and wrapped with heavy-duty stretch film to eliminate any moisture or impact damage during international maritime transit.
Tailored Customization Services:
Brand Identity: Laser engraving or casting of your unique private brand identity.
Appearance Color: Available in classic industrial black, construction yellow, grey, or custom brand colors.
Dimensional Adjustments: Bolt hole patterns and pitch diameters can be customized based on specific equipment blueprints.
