Product Details
When we build a steel track undercarriage, our first concern is always how it will perform after years of real work in the field. A good-looking product means very little if it cannot stand up to continuous heavy-duty operation.
For that reason, we don't use thin steel plates or simple welded structures just to reduce manufacturing costs. The main load-bearing frame is built from thick high-strength alloy steel with an integral forged structure, giving the chassis much better rigidity and overall strength. This helps prevent deformation, bending, and metal fatigue after long periods of carrying heavy loads.
We've worked with drilling equipment long enough to know what these machines go through every day. High torque, constant vibration, rough terrain, and repeated impacts are simply part of the job. So before production even begins, we pay close attention to how forces are distributed throughout the chassis. The structural layout is carefully optimized, and every major stress point and critical weld is reinforced to handle demanding working conditions with greater confidence.
Product Advantages
With durable components and effective sealing systems, the crawler assembly requires less frequent maintenance. This helps customers reduce downtime and improve overall equipment availability.

Customized Design Supporting Scheme
Before production, our team sort of communicates a lot, to really confirm each key detail. We will consider your drill rig model, the real construction terrain, what the load asks for, traveling speed and the installation situation, then we adjust track gauge , ground clearance, overall dimensions, mounting structure and the hydraulic matching parameters, one by one, step by step . There is no rigid fixed template, like nothing straight from a book-every design is customized so it fits your on-site working conditions as good as possible.
And to make installation and docking easier for clients, we provide full design support documents right after order confirmation. That means detailed 2D drawings, 3D models, and the official assembly drawings as well. Our design team can also provide remote technical guidance during the whole process. So whether you only need small parameter tweaks, or you actually need full non-standard chassis redesign, we can deliver steady, workable, and more cost-effective customized solutions. These help your equipment gain better operational stability and adapt better to the site.

Product Application
Our tracked chassis is designed for a wide range of heavy-duty equipment. It can be used in excavators, underground drilling rigs, exploration drilling rigs, roadheaders, slag scrapers, and power supply vehicles. With its strong load capacity, excellent stability, and reliable performance, the tracked chassis provides an ideal mobility solution for demanding construction, mining, and engineering applications.

Production Line Process
We have built a dedicated, full process production line for steel track undercarriage for exploration drill rig. we don't really lean on generic processing workshops at all. like, every step from raw material cutting, through integral forging, and welding-then into precision finishing, plus the final testing is done in house under our strict control.
We use full CNC precision machining for all key structural components, keeps things in a steady track. This approach makes sure every batch lands consistent in size and performance, so it avoids dimensional deviations and that unstable quality people often see with ordinary processing. We also set up a full process traceable quality inspection system, and we do careful checks for material hardness, welding firmness, assembly accuracy and load bearing capability before anything leaves.

FAQ
Q: Can tonnage be customized?
A: Our customiz ation range is pretty much fully flexible, covering everything from 3 tons to 200 tons , so it can kinda match all sorts of project requirements. The standard models are staying in stock, so they can be dispatched immediately, any time. As for items that are not standard, the usual manufacturing cycle tends to run 10 to 25 working days. For bulk orders, or if the quantity is higher, we're of course open to discuss the terms , and also rework the schedule, aiming to shorten delivery time, so we can better support our customers and their project progress.
Q: Can the width and total length of the equipment be resized as needed?
A: We support a kind of full, non-standard customization for all the core equipment dimensions. Like equipment length, equipment width, the track gauge , the ground clearance, plus the mounting flange parameters, so we can tweak pretty much every single detail to fit your actual installation and construction requirements. Once the contract is confirmed , we will send you the full 2D drawings and 3D models, plus assembly drawings too, completely at no cost.
Q: Do you have CE and customs clearance documents? Can delivery be made to designated ports in China?
A: Equipped with CE certification along with a full suite of customs clearance documents, ok. We can support FOB , CIF, DDP and other trade terms , also, we do accurate calculation of shipping costs and for big orders we offer free delivery to the specified domestic ports.
Q: How long is the warranty period for the entire machine?
A: We provide a single , unified one-year warranty for the whole machine, to fully safeguard customers' equipment use, not just certain bits. Also, we maintain a regular stash of original vulnerable parts. So, we can handle quick replacements and after-sale servicing, in a way that cuts down your equipment downtime, quite significantly.
Q: How to choose between steel tracks and rubber tracks?
A: We have two mainstream track options, to cover different work scenarios, pretty nicely. Our steel tracks bring high load bearing capacity, great impact resistance and top wear resistance, so they are an ideal pick for heavy duty mining exploration operations. On the other hand, our rubber tracks don't cause any damage to paved surfaces. They work especially well for municipal engineering jobs, and for indoor pavement construction projects too, really.
