A broad selection of undercarriage configurations ensures dependable traction across muddy, soft, and uneven ground-keeping your drill rigs, excavators, and other track-mounted machines productive even in tough environments. Reduced slippage and fewer unexpected interruptions help maintain stable, consistent on-site output.

Key options include:
Final drive choices – hydraulic or electric motors to suit your power preferences.
Frame connection – intermediate beams can be joined to side frames via full welding or bolted assembly.
Sealed rollers and idlers fitted with floating oil‑seals remove the need for re‑lubrication over long service intervals.
The track tensioning system uses grease cylinders paired with shock‑absorbing springs for straightforward track adjustment.
Track guards: optional chain guards are available for enhanced component protection.
Track shoes – high-strength alloy steel or wear-resistant rubber tracks for superior impact resistance and longer service life.

To ensure product accuracy and reliable delivery quality, our factory adheres to a standardized production process with dedicated quality checks at each phase.

Production begins with laser cutting, CNC bending and precision machining, establishing strict tolerances and consistent quality standards from the very first production stage.

During final assembly, every bolt is torqued to specification and secured with thread-locking compound. This seemingly minor design delivers tangible benefits: more robust joints and extended intervals between maintenance cycles.
