The track-based propulsion system of a bulldozer that provides mobility, traction, and weight distribution across terrain.
Technical details and manufacturing context for Undercarriage (Tracks)
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Track Gauge | 1500–2500 mm | Determines stability and compatibility with transport trailers. |
| Track Width | 400–900 mm | Wider tracks reduce ground pressure but increase resistance. |
| Track Pitch | 150–250 mm | Affects ride comfort and component wear.ISO 10265 |
| Number of Track Links | 35–60 links | Depends on track length and pitch. |
| Ground Contact Area | 1.5–4.0 m² | Critical for flotation on soft ground. |
| Ground Pressure | 30–80 kPa | Lower pressure minimizes soil compaction and rutting. |
| Maximum Travel Speed | 3–10 km/h | Higher speeds reduce traction and increase wear. |
| Tractive Force | 50–300 kN | Must exceed rolling resistance and grade demands. |
| Operating Temperature Range | -20–+50 °C | Seals and lubricants degrade outside this range. |
| Material Grade (Track Shoes) | GB/T 3077 40Mn2 | High manganese steel for wear resistance.GB/T 3077 |
| Hardness (Track Shoes) | HRC 45–55 HRC | Higher hardness improves wear life but may increase brittleness. |
| Total Undercarriage Weight | 2000–8000 kg | Affects machine balance and transport weight. |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
This component is essential for the following industrial systems and equipment:
| pressure: | Max 15 MPa (hydraulic system) |
| other spec: | Max flow rate: 200 L/min, Slurry concentration: <30% solids by weight |
| temperature: | -40°C to +80°C |
Indicative industry ranges for design and RFQ preparation. Confirm the exact figures and applicable standard with the manufacturer before specifying.

CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The undercarriage provides mobility, traction, and weight distribution. It converts engine power into movement and supports the entire machine, enabling operation on soft or uneven terrain.
Wider tracks reduce ground pressure, improving flotation on soft ground, but increase rolling resistance and may affect transport width. The typical range is 400–900 mm, but the optimal width depends on the application.
Signs include excessive track sag, uneven wear on track shoes or rollers, leaking seals, and increased noise or vibration. Regular inspection of track tension and component wear is essential.
Track pitch affects ride comfort and component wear, and is specified per ISO 10265. Material grade, such as GB/T 3077 40Mn2, influences wear resistance. Always confirm these values with the manufacturer for your specific model.
