Crane undercarriage parts are the foundational components that ensure the stable operation, load-bearing capacity, and maneuverability of crawler cranes. These critical crawler crane components serve as the “feet” of the cranes, directly contacting the ground and withstanding immense pressure, friction, and external impacts in harsh working environments such as construction sites, mining areas, and utility maintenance projects.

What are the Crane Undercarriage Parts

The crawler crane undercarriage parts mainly include track shoes, track rollers, top rollers, idler wheels, drive sprockets, etc.

The track shoes primarily increase the ground contact area and support the crawler crane body; the track rollers can support the weight of the crawler crane and allow the tracks to move forward; the top rollers will support the tracks from above, this help maintaining a certain tension; the idler wheels guide the tracks to rotate correctly, preventing deviation and derailment; and the drive sprockets transmit power, connecting to the travel reducer and directly transferring power to the tracks, thus driving the entire undercarriage forward.

A Comprehensive Portfolio of Crawler Crane Components

Shandong Value Machinery offers an extensive range of undercarriage parts covering major global crawler cranes, with crane tonnage from 35 to 1600 tons. Our product lineup encompasses every critical component required for crawler crane undercarriage systems, making us a one-stop shop for parts for cranes:

Suitable Materials Ensure Crane Undercarriage Parts Performance

Selecting appropriate materials for crane undercarriage parts based on crane tonnage is critical for safety, compliance, and efficiency.

This targeted approach ensures compliance with ISO/ASME standards, extends part service life by 50–80%, optimizes total ownership costs, and boosts crane maneuverability and load capacity. As a leading crawler crane components supplier, Shandong Value Machinery prioritizes tonnage-material matching, delivering reliable, cost-effective parts that minimize downtime. Our tailored solutions meet global clients’ diverse needs, reinforcing safety and productivity across construction, mining, and offshore projects.

For example, track shoe material: Below 100 tons: Track shoes made of 35SiMn and 31Mn2Si offer a cost-effective balance of strength and wear resistance.

100-300 tons: 31Mn2SiMo and 28CrMnMo materials deliver enhanced tensile strength and fatigue resistance.

300-600 tons: 31Mn2SiMoNi provides ultra-high impact toughness and load-bearing capacity.

Above 600 tons: G22NiMoCr5-6 offers top-tier wear and corrosion resistance, tailored for ultra-heavy-duty cranes, ensuring stable, safe operation in the most demanding industrial scenarios.

Quality Control

We adhere to strict ISO 9001 quality management standards, and every crane part undergoes rigorous processes to ensure reliability and durability. We have strict quality inspection procedures, including:

Ultrasonic testing: A non-destructive method that detects internal flaws (e.g., cracks, inclusions) in crane undercarriage parts by transmitting high-frequency sound waves, ensuring structural integrity without damaging components.

Magnetic particle testing: Identifies surface and near-surface defects (such as microcracks) in ferromagnetic materials (e.g., alloy steel track pads) by applying magnetic fields and iron particles, highlighting irregularities.

Tensile testing: Measures the tensile strength, yield strength, and ductility of materials (e.g., 31Mn2SiMoNi) by subjecting samples to controlled pulling forces, verifying their ability to withstand load stress.

Impact testing: Evaluates the toughness and resistance to sudden fracture of materials under dynamic loading (e.g., extreme impacts in mining sites), ensuring parts perform safely in harsh conditions.

Hardness testing: Quantifies a material’s resistance to indentation or abrasion (e.g., HRC for sprockets), reflecting its durability and suitability for specific tonnage-related wear demands.
