This page explains how Crawler 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 mobile base system of a crawler crane that provides stability and mobility through tracked locomotion.
Technical details and manufacturing context for Crawler Undercarriage
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Track Gauge | 2000–6000 mm | Determines stability and transport width. |
| Track Width | 500–1200 mm | Affects ground pressure and flotation. |
| Ground Contact Length | 3000–8000 mm | Influences stability and traction. |
| Ground Pressure | 0.05–0.15 MPa | Higher values risk sinking in soft soil. |
| Max Travel Speed | 1.0–3.0 km/h | Limited by hydraulic drive and safety. |
| Gradeability | 30–50 % | Slope capability without losing traction. |
| Max Drawbar Pull | 100–500 kN | Critical for towing or pulling loads. |
| Operating Pressure | 20–35 MPa | Hydraulic system pressure for drive and controls. |
| Operating Temperature | -20–50 °C | Outside range may affect seals and hydraulics. |
| Ingress Protection | IP54–IP65 | Protects electrical components from dust and water.IEC 60529 |
| Material Grade | Q345B–Q690D | Higher grades for heavier loads and wear resistance.GB/T 1591 |
| Total Weight | 10–100 t | Includes undercarriage without upper structure. |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.

It provides the mobile base for a crawler crane, distributing weight over a large area to reduce ground pressure and enable travel on soft or uneven terrain. It also provides traction and stability during lifting operations.
High-strength alloy steel, wear-resistant steel plate, and forged steel components are commonly used. Material grades may range from Q345B to Q690D per GB/T 1591, depending on load requirements.
Track gauge, track width, ground contact length, ground pressure, max travel speed, gradeability, max drawbar pull, operating pressure, operating temperature, ingress protection, material grade, and total weight. These are reference ranges; confirm with the manufacturer.
Regular inspection of track tension, wear on rollers, sprockets, and idlers, and hydraulic system integrity is essential. Look for signs of fatigue, leaks, or abnormal wear. Follow manufacturer guidelines for maintenance intervals.
