Hitachi KH300-3 Guide Wheel Production Process

Our Hitachi KH300-3 crane idlers undergo multiple rigorous production procedures. The idlers are cast from high-strength 35SiMn alloy steel and manufactured to OEM specifications. Advanced heat treatment improves hardness and structural strength for demanding working conditions. Meanwhile, we perform surface quenching on wheel bodies subject to heavy wear. This process achieves a surface hardness of HRC 45–55, improving wear resistance and extending service life. This helps maintain stable crane operation while reducing maintenance downtime and operating costs.

The Hitachi KH300-3 crane idler is designed for heavy-duty crawler crane undercarriage systems operating in:

• Bridge construction projects
• Wind power installation
• Offshore lifting operations
• Steel structure assembly
• Mining equipment installation

Its hardened surface structure helps reduce undercarriage wear under high-load working conditions.
