Product Details
This product is engineered for demanding heavy-load applications, boasting a rated load capacity of 20 tons and meeting the operational requirements of various medium-to-large heavy engineering equipment. Featuring a robust structural design, it excels in harsh outdoor environments-such as mines and construction sites offering exceptional stability, durability, and versatility across complex terrains.
The main chassis is constructed from high-strength carbon steel and industrial-grade thickened steel plating; critical components including the main frame, load-bearing brackets, and connection points have undergone reinforcement and thickening. The materials are rigorously selected for superior compressive strength, impact resistance, and deformation resistance, effectively preventing issues such as frame bending, warping, or structural failure during heavy-load operations and significantly extending the equipment's service life.
The 20 ton heavy steel track undercarriage features an integrated, reinforced steel structure, moving away from the simplified designs found in lightweight chassis. The structure ensures high integrity and uniform load distribution, resulting in smooth operation with minimal swaying or drifting. Furthermore, the unit supports customization of dimensions, track gauge, ground clearance, mounting points, and connection structures, allowing for seamless integration with specialized equipment such as drilling rigs, crushers, transport platforms, and excavators.
Our Core Advantages
Exceptional Load-Bearing Capacity
Designed for heavy-duty applications, the 20-ton steel track undercarriage provides outstanding strength and stability, ensuring reliable support for large machinery in demanding working environments.
Superior Durability and Wear Resistance
Manufactured with high-quality steel materials and advanced processing technology, it offers excellent resistance against impact, abrasion, and harsh operating conditions, extending service life and reducing maintenance costs.
Enhanced Stability and Safety
The robust track structure delivers improved ground contact and balance, allowing equipment to operate smoothly on uneven, muddy, or rough terrain while maintaining excellent stability.
Strong Adaptability to Harsh Environments
Suitable for construction, mining, agriculture, and other heavy-duty industries, the undercarriage performs reliably in challenging conditions such as heavy loads, steep slopes, and difficult terrains.

Customized Design Solutions
A standard 20 ton heavy steel track undercarriage cannot always perfectly match the actual requirements of every machine and working condition. Therefore, we provide customized solutions that allow the undercarriage structure, dimensions, and component configuration to be modified according to each customer's equipment and application environment.
Our engineering team is able to adjust key specifications based on different project requirements, including overall length and width, track gauge, ground clearance, mounting positions, and connection structures. Whether the undercarriage is intended for drilling rigs, crushing equipment, transport platforms, excavators, or other special-purpose machinery, we can develop a suitable crawler system to ensure proper installation, smooth operation, and reliable stability during use.
Each customization project begins with a detailed evaluation of the customer's equipment information. We consider factors such as machine weight, working terrain, expected load capacity, and available installation space before starting the design process. Based on these conditions, we select suitable steel materials, optimize the frame structure, and adjust the track system layout to achieve the required strength and durability.

Chassis Components
This track uses a flexible connection design between components. It helps the crawler adapt to different ground conditions and improves movement comfort.

Factory Production Line
The production of our 20 ton heavy steel track undercarriage follows a complete manufacturing process, covering material preparation, cutting, machining, welding, assembly, surface treatment, and final inspection. Each step is carefully controlled to ensure the finished product meets the requirements of strength, precision, and long-term reliability.
The production starts with high-strength steel plates selected according to the structural requirements of heavy-duty applications. Advanced cutting and forming equipment are used to process the main frame components, ensuring accurate dimensions and stable structural performance. After machining, experienced welders complete the assembly of the main frame and track components, creating strong joints that can withstand heavy loads, impact, and continuous operation.
During the assembly stage, key parts such as track rollers, idlers, sprockets, track chains, and mounting components are installed and adjusted to achieve smooth movement and reliable performance. Before shipment, every undercarriage goes through strict quality checks, including dimensional inspection, structural inspection, and operation testing.

FAQ
Q: What is the minimum order quantity (MOQ)? Is there stock available? What is the lead time?
A: The minimum order quantity is only one unit, and we are able to provide customized solutions even for a single-piece order based on your specific requirements.
For our standard ready-to-ship models, delivery can usually be arranged within 7 to 10 days. Customized products generally require around 15 to 25 days for production, depending on the design and specifications. For larger quantity orders, we are also open to discussing a more suitable production schedule to better meet your project needs.
Q: Can the undercarriage width and total length be modified according to requirements?
A: Chassis system dimensions-such as overall length, width, track width, ground clearance, and mounting flange configuration-can be adjusted to meet your customization requirements. Once the order agreement is finalized, we provide 2D drawings, 3D models, and assembly diagrams free of charge to facilitate efficient installation and equipment integration.
Q: Do you support customization of steel undercarriages with different load capacities?
A: We offer customized solutions for a wide range of track undercarriage models, covering capacities from 3 tons to 200 tons. These crawler chassis systems are designed to work with various types of heavy equipment, such as exploration drilling rigs, mucking machines, rotary drilling rigs, and compact excavators, providing reliable support and stable performance in different operating conditions.
Q: Can the chassis be used as a mobile power station for multiple machines?
A: Yes. A tracked generator chassis can serve as a mobile power hub for multiple pieces of equipment. It powers electric-drive crushers, drills, pumps, lighting towers, and other site equipment. This is especially useful in remote locations where grid power is not available. One generator on a tracked chassis can replace several smaller generators scattered across the site.
Q: What packaging is used for shipping? How are sea or land freight costs calculated?
A: Before shipment, the chassis is coated with anti-rust paint and packaged in a steel or wooden frame to prevent damage during transit.
We accept standard trade terms such as FOB, CIF, and DDP. Simply provide us with the destination port and your preferred shipping method, and we will calculate the exact sea or land freight costs for you.
