The IHI CCH3000 top roller is a crucial undercarriage component designed to guide the track chain and support the crane’s weight, and it is manufactured by various suppliers using specific materials and heat treatment processes. The original equipment manufacturer (OEM) for the crane is IHI Construction Machinery Limited, which was acquired by KATO Works.
Product Specifications
Aftermarket manufacturers provide top rollers that are compatible with the IHI/KATO CCH3000 model, often emphasizing durability and quality control to match or exceed OEM standards.
- Material: The roller body is typically made from 40Mn2 steel, while the pin is made of 42Cr steel.
- Technology: Forging techniques are commonly used in manufacturing the roller.
- Heat Treatment: The parts undergo rigorous heat treatment processes, including whole quenching and tempering, followed by surface hardening, to enhance mechanical properties, yield strength, and tensile strength.
- Bushing: Suppliers often use 100% fine copper bushings to ensure reliable performance.
- Seals: High-quality floating seals are used to retain lubricating oil and prevent contamination from dirt and mud.
- Function: The top roller (also known as a carrier roller or upper roller) holds the track shoe up, helping to maintain proper tension and guiding the crawler movement
A crane top roller is a type of wheel that is mounted on the top of a crane’s boom. It is designed to support and guide the hoisting rope or chain as it lifts and lowers heavy loads. The top roller enables the crane to smoothly and safely move the load along the boom’s length. It is a critical component of the crane’s lifting system and must be carefully maintained to ensure its safe and efficient operation.
