Murphy Construction Machinery (Shandong) Co., Ltd. is one of the leading manufacturers and suppliers of crawler undercarriage in China. If you're going to buy the newest crawler undercarriage, welcome to get pricelist from our factory. All customized products are with high quality and low price.

Product Details
This Crawler Undercarriage is specially developed for various types of belt walking construction machinery, with excellent landing stability, wear and tear resistance, and complex site traffic capacity. The entire walking assembly is made of high-quality steel and high-precision transmission components, which can adapt to high-intensity and harsh working scenarios, and maintain stable working performance during long-term continuous operation.
Whether it is muddy construction sites, rugged mine tunnels, loose desert sandy areas, or undulating farmland areas, this steel walking structure can provide strong traction, large tonnage bearing capacity, and flexible off-road passability, making it very suitable for engineering machinery manufacturers, equipment integrators, and industrial machinery traders to purchase supporting walking assemblies.
Our Core Strengths
For many years, we have been dedicated to the research and manufacturing of track assemblies, providing mature and feasible walking support solutions for engineering construction equipment, agricultural machinery, drilling platforms, crushing and screening equipment, and customized special track vehicles. Experienced engineers follow up on the design and implementation of the plan throughout the entire process, ensuring that each walking assembly is structurally firm, runs smoothly, and exhibits outstanding comprehensive performance under high-intensity and harsh working conditions.

Customized Design Supporting Scheme
The equipment parameter requirements vary in different usage scenarios. We can tailor a complete set of Crawler Undercarriage matching solutions based on the customer's overall dimensions, on-site operating environment, rated load capacity, track landing width, and walking drive mode. At the same time, we undertake OEM, ODM OEM, OEM and customized processing services to help our cooperative customers shorten the overall R&D cycle and improve the overall performance of the machine.

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.
