Product Details
The Tracked Undercarriage for Rotary Drilling Rig is the core walking and load-bearing assembly of rotary drilling equipment, characterized by hydraulic drive, heavy-duty stability, torsional and seismic resistance, and strong off-road capability. Customization of track length, grounding width, track plate thickness, overall track gauge, and walking drive structure is available as needed, suitable for various types of rotary drilling equipment on the market. The equipment can seamlessly integrate with intelligent electronic control, hydraulic control, and remote control systems, adapting to the upgrading and transformation of new intelligent rotary drilling rigs. Adopting an integrated modular design, it can be quickly assembled and debugged without changing the structure of the equipment host.
Our undercarriages use low-speed, high-torque motors that deliver greater driving force where it matters - on slopes, in mud, and across uneven ground. The crawler track and chain plates are screw-fixed for straightforward maintenance, reducing downtime and keeping your rig on the job.
These undercarriages are built for rotary drilling rigs used in foundation construction, water well drilling, mineral exploration, piling, geotechnical work, and municipal construction. They also serve core drills, jet grouting rigs, down-the-hole drills, anchor drills, and trenchless drilling equipment. Whether you are retrofitting existing equipment or building from the ground up, we provide the tracked chassis that makes it work.
Product Advantages
Designed for demanding industries, this crawler system offers excellent resistance against impact, dust, and harsh working conditions. It delivers dependable support for mining, excavation, and construction equipment.
Customized Design Supporting Scheme
Based on the customer's drilling rig model, construction scenario, load-bearing capacity, track specifications, and driving method, a one-to-one customized rotating drilling rig track type chassis complete set solution is available. The product has passed CE/EMC/ISO9001 international certification and can withstand harsh environments such as outdoor dust, humidity, high temperature, and heavy loads. It has a low failure rate and easy maintenance. Supporting OEM and ODM OEM, helping customers shorten equipment development cycles and enhance the core competitiveness of the entire machine.
Durable Steel Structure Configuration
The Tracked Undercarriage for Rotary Drilling Rig is formed by forging thick high-strength alloy steel plates, which have excellent wear resistance, impact resistance, and deformation resistance. It can withstand the dynamic torque and continuous heavy load pressure generated by rotary drilling for a long time. In response to common problems such as eccentric force and high-frequency shaking of the drilling rig during rotation operations, the chassis mechanics architecture is optimized to effectively buffer operational vibrations, prevent body displacement and shaking, and significantly improve drilling construction accuracy and overall stability. The high-strength integrated structure significantly reduces component wear, reduces the frequency of failures and shutdowns, lowers on-site operation and maintenance costs, and effectively extends the overall service life of drilling equipment.

Chassis Components
Made for rocky and harsh areas, this track style focuses on strength and wear resistance. It helps equipment move safely over difficult terrain.
Production Line Process
The chassis components are precision shaped through laser cutting and CNC bending, with precise dimensions and regular components. Relying on automated robot welding technology, the welds are uniformly dense, avoiding welding deformation defects and ensuring the overall structural strength of the chassis. The core installation position is precision machined using a gantry machining center, with strict control over assembly accuracy. The workpiece has undergone shot blasting rust removal, automatic spraying, and high-temperature drying treatment, with excellent anti-corrosion, rust prevention, and weather resistance, making it suitable for long-term outdoor drilling operations. Standardized assembly of finished products, adding special thread glue to bolts and locking them with standard torque to eliminate the risk of loosening during long-term operation and ensure the long-term stable operation of equipment.

FAQ
Q: Can the tonnage be customized?
A: Yes, absolutely. The standard range is 3 to 200 tons, and we can tailor it to your specific needs. Common models are typically in stock and available for immediate shipment. For non‑standard customization, lead time is about 10 to 25 days. For larger orders, we can negotiate a shorter delivery cycle.
Q: Can the width, total length, and other dimensions be adjusted as required?
A: No problem. The length, width, track gauge, ground clearance, mounting flange, and other parameters can all be customized to your specifications. After signing the contract, we provide free 2D drawings, 3D models, and assembly diagrams to help you install and connect quickly – saving you time and guesswork.
Q: Do you have CE certification and customs clearance documents? Can you deliver to designated domestic ports?
A: Yes, we have CE certification and a complete set of customs clearance paperwork. We support FOB, CIF, DDP, and other trade terms. Shipping costs are calculated accurately with no hidden fees. For large orders, we offer free delivery to any designated port within China.
Q: What is the warranty period for the complete machine?
A: The entire machine comes with a standard one‑year warranty. We keep a regular stock of original wear parts and commonly used accessories, so replacements are always available when you need them – minimising downtime.
Q: How do I choose between steel tracks and rubber tracks?
A: Steel tracks offer strong load‑bearing capacity, wear resistance, and impact resistance – ideal for heavy‑duty drilling in mining and other harsh conditions. Rubber tracks are non‑damaging to surfaces, making them suitable for municipal projects, indoor construction, or paved road work. The choice really depends on your specific working environment.
