Crawler Undercarriage

Crawler Undercarriage
Product Introduction:
The Crawler Undercarriage belongs to an integrated walking assembly structure, which is suitable for exploration drilling rigs, slag removal machinery, and tunnel excavation engineering equipment. The overall dimensions can accurately adapt to various host equipment, and customers can directly connect with the source production factory, eliminating the need for intermediate distributors to increase prices.
Enterprises can establish their own dedicated R&D and design departments to customize load-bearing capacity, hydraulic walking systems, and unconventional track assemblies according to customers' actual usage requirements, matching the unique operating environment and working conditions of various equipment. With the help of refined structural engineering design and high-strength integrated molding structure, this walking assembly runs smoothly, has a longer service life, and can effectively reduce the investment in subsequent maintenance and upkeep.

Durable Steel Structure Configuration

 

The main body of the Crawler Undercarriage is made of high-strength structural steel plates, which have excellent wear resistance, impact resistance, and compression deformation resistance; Adopting fully automatic precision welding technology combined with CNC precision cutting processing, the dimensional error of the finished product is controllable, and the overall structural strength and integrity meet heavy-duty standards.

The chassis frame has undergone special optimization for heavy load and force, and can still operate smoothly under long-term full load operation, effectively reducing the vibration amplitude during operation. The hard steel main frame extends the overall service life, reducing the frequency and cost of component maintenance and replacement from the root.

FAQ

 

Q: What types of mechanical equipment can be fitted with a steel-track undercarriage assembly?

A: Our Crawler Undercarriages are suitable for a wide range of machines, including tracked intelligent robots, drilling platforms, agricultural machinery, aerial work platforms, material transfer carriers, mining equipment, and various custombuilt industrial special machinery.

Q: Can the chassis width, overall length, and ground clearance be customized? Do you provide installation drawings?

A: Yes. Length, width, track gauge, ground clearance, and mounting flange dimensions all support non‑standard customization. After the contract is signed and the order is placed, we will provide free 2D machining drawings, 3D models, and installation dimension drawings to make machine assembly straightforward.

Q: Do you support steel chassis customization for different tonnages? What is the maximum load capacity?

A: We support OEM/ODM customization across the full tonnage range from 3 to 200 tons. These undercarriages are suitable for geological exploration drilling rigs, slag excavators, rotary drilling rigs, small excavators, and similar equipment. The main material is 40Mn2 alloy steel, which undergoes a full quenching heat treatment. This gives it stable load performance and excellent resistance to deformation and bending, even in harsh conditions such as mining gravel, mud, and standing water.

Q: How long is the warranty period? Can you supply wear parts on a long‑term basis?

A: The complete undercarriage comes with a one‑year standard warranty. Commonly used wear parts-such as track chains, drive wheels, idler wheels, and support rollers-are kept in stock. We also offer technical support including online video guidance for installation and commissioning, remote troubleshooting, and more, to help minimise downtime and reduce your economic losses.
