This is a complete set of excavator undercarriage components, commonly known as the “Four Wheels and One Belt” system. These parts form the core of the excavator’s walking mechanism, directly affecting its stability, maneuverability, and service life.
All components are manufactured with high-quality wear-resistant steel and undergo precision heat treatment to withstand extreme working conditions, including heavy loads, high impact, and continuous friction. They are fully compatible with major excavator brands such as XCMG, CAT, Komatsu, Hitachi, Sany, and more, ensuring reliable performance and easy replacement.
The undercarriage system is widely used in construction, mining, demolition, and forestry applications, providing a solid foundation for excavators to operate on uneven, rough, and soft terrain.
| Part Name | Function |
| Track Chain / Track Assembly | Provides traction and distributes the machine’s weight evenly on the ground. |
| Sprocket (Drive Wheel) | Drives the track chain to move the excavator forward/backward. |
| Idler (Front Guide Wheel) | Guides the track and maintains proper tension to prevent derailment. |
| Track Rollers (Bottom Rollers) | Supports the machine’s weight and reduces friction between the track and the frame. |
| Carrier Rollers (Top Rollers) | Supports the upper track section to prevent sagging and excessive vibration. |
| Track Adjuster & Recoil Spring | Adjusts track tension and absorbs shocks during operation. |
| Track Shoes / Pads | Attach to the track chain, providing grip and protecting the chain from direct wear. |
| Bucket Teeth, Adapters & Pins | (Shown in the image) Wear parts for the excavator bucket, including teeth, adapters, pins, and locks. |
