This page explains how Undercarriage is classified within Machinery and Equipment Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.
The structural base assembly of a hydraulic excavator that supports the upper structure and provides mobility.
Technical details and manufacturing context for Undercarriage
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Track Gauge | 1800–2200 mm | Determines stability and transport width |
| Track Shoe Width | 500–800 mm | Wider shoes reduce ground pressure |
| Ground Contact Length | 2500–3500 mm | Affects stability and traction |
| Ground Pressure | 30–60 kPa | Higher pressure may damage soft ground |
| Max Travel Speed | 3.0–5.5 km/h | Higher speed reduces traction |
| Gradeability | 30–70 % | Maximum slope angle in percent |
| Hydraulic Oil Flow | 150–250 L/min | Determines travel motor speed |
| Track Tension | 50–100 kN | Insufficient tension causes derailing |
| Material Grade | Q345B | High-strength low-alloy steelGB/T 1591 |
| Total Weight | 3000–8000 kg | Affects transport and ground pressure |
| Operating Temperature | -20–50 °C | Outside range may affect seals and hydraulics |
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: | N/A (structural load-bearing component, not fluid pressure) |
| other spec: | Maximum ground pressure: 0.5-1.2 kg/cm², Maximum travel speed: 0-5.5 km/h, Maximum gradeability: 70% (35°) |
| temperature: | -40°C to +50°C (operational ambient range) |
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 supports the entire machine's weight, provides stability during excavation, and enables mobility via tracks or wheels. It also houses the swing bearing for 360-degree rotation and travel motors for propulsion.
Track gauge typically ranges from 1800 to 2200 mm, and track shoe width from 500 to 800 mm. Wider shoes reduce ground pressure, but these values must be verified for the specific model.
Ground pressure (30–60 kPa) affects soil compaction and the machine's ability to operate on soft ground. Higher pressure may damage soft ground, so it must be matched to the application.
Track tension should be within 50–100 kN. Insufficient tension can cause derailing, while excessive tension increases wear. Regular inspection and adjustment are necessary, following manufacturer guidelines.
