The crane idler is an essential guiding and tensioning part of the crawler crane undercarriage. It guides the track movement and maintains proper track tension, ensuring flexible turning, stable traveling and reduced track wear during heavy-duty operations. Our idlers are fully compatible with mainstream crawler crane brands including Kobelco, Manitowoc, Liebherr, Sumitomo and other global famous models.

Our crane idlers are forged from high-strength alloy steel and processed with professional quenching and tempering treatment. The wheel surface features high hardness, excellent wear resistance and strong impact resistance, effectively avoiding deformation

Adopting precision machining and advanced sealing structure with reliable floating oil seals, our idlers effectively prevent sand, dust and water intrusion, keeping internal lubrication stable and avoiding oil leakage.

All idlers are manufactured strictly in accordance with OEM standard dimensions, achieving perfect assembly accuracy and easy direct replacement. As a professional crawler crane undercarriage parts manufacturer, we have complete production and quality control systems. Every idler undergoes strict testing procedures including hardness testing, tensile testing, impact testing and magnetic particle inspection to eliminate internal and surface defects.
