Product Overview The KATO & TADANO Crane Hydraulic Cylinder Repair Kit is a precision-engineered maintenance solution exclusively designed for hydraulic cylinders of KATO and TADANO cranes-two globally renowned brands with a legacy of excellence in lifting equipment manufacturing . This comprehensive kit integrates high-performance sealing components to restore hydraulic system integrity, prevent fluid leakage, and ensure consistent lifting performance for heavy-duty operations.
Core Features & Specifications 1. Premium Material Composition Crafted with a synergistic blend of NBR (Nitrile Butadiene Rubber), FKM (Fluoroelastomer), and PTFE (Polytetrafluoroethylene), the seals deliver exceptional resistance to wear, corrosion, and hydraulic oils . Polyurethane enhancements further boost durability, enabling reliable operation under pressure ranges up to 35 MPa .
2. Wide Temperature Adaptability Engineered to withstand extreme working conditions, the kit performs seamlessly in temperatures ranging from -35°C to 160°C (depending on material type): NBR components excel at -35°C to 100°C, while PTFE variants extend thermal resilience to 160°C .
3. Precision Compatibility Tailored for KATO (e.g., KR25H-V3) and TADANO crane models, the kit includes piston seals, rod seals, O-rings, guide strips, and backup rings-all manufactured to OEM specifications . It accommodates cylinder diameters up to 2000mm and sliding speeds of 0.005-1.5 m/s, ensuring a perfect fit for most hydraulic cylinder configurations .
Key Advantages 1. Leak-Proof Performance: Effectively maintains hydraulic pressure by eliminating fluid seepage, critical for safe load handling in construction, port, and mining environments .
2. Minimized Downtime: All-in-one design provides complete repair components, reducing maintenance time and operational disruptions .
3. Long Service Life: Wear-resistant materials and robust structural design extend cylinder lifespan, lowering replacement frequency and total ownership costs .
4. Global Quality Compliance: Meets ISO 9001, CE, and ROHS standards, adhering to international safety and performance benchmarks for heavy machinery parts .
Application Scenarios Ideal for maintenance of mobile cranes, truck-mounted cranes, and hydraulic lifting systems used in: 5. Construction (steel beam installation, concrete lifting) 6. Port logistics (cargo loading/unloading) 7. Mining operations (heavy equipment positioning) 8. Industrial machinery repair workshops Brand Heritage & Reliability Backed by the legacy of KATO and TADANO-leaders in crane manufacturing since 1919-this repair kit embodies the "fueki-ryuko" (immutability and fluidity) philosophy of continuous innovation and uncompromising quality . It is the preferred choice for professional technicians seeking OEM-grade reliability in hydraulic system maintenance.
