Crawler Undercarriage Assembly

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

Steel crawler undercarriage. Drill rigs, exploration units, tracked carriers. Mud, rock, or mountain grade-it doesn't care.
This isn't a rubber-track compromise. It's a steel assembly built for sites where ground conditions eat equipment alive. Q345B beam, sealed rollers, hardened sprockets. If your machine crawls and needs to keep crawling after the ground turns to slurry, this is the base it sits on.

 

Your machine's mounting pattern. Not a catalog number.
Send the tonnage and bolt layout. We build the complete assembly-track frame, lower frame, travel base-as one matched unit. From 3 to 200 tons. No adapter plates, no re-drilling on your side. The structural core is proven; only the interface is yours. That's how a custom build avoids a custom timeline.

 

Drawings in, proposal out. Spares after the sale.
Steel systems in the 20 to 80 ton band often reuse existing frame dimensions. Beyond that, dedicated engineering. Replacement rollers and idlers ship from stock. The quote costs nothing, and neither does the first conversation.

Your machine does not have to fit our chassis-our chassis fits your machine. We build crawler undercarriages for drilling rigs, exploration equipment, tracked carriers, compact engineering drills, solar piling machines, and geological survey rigs, covering a wide span of operating weights. Whatever you mount on tracks, the platform underneath can be made to suit it.

No host machine redesign required for stock frames. We build matching interfaces from your drawings, mounting sizes and hydraulic schematics, for new builds or equipment upgrades.

A machine can run on the wrong undercarriage for months before anyone notices. It tracks. It moves. But it doesn't carry load the way it should. The chain, sprocket, and roller geometry are slightly off for the ground you actually work on, and the wear tells the story later.

Then there's the mounting side. A standard frame rarely lines up with a non-standard machine. Bolt patterns don't match. The center frame sits too high or too low. Your engineers end up redrilling plates or shimming gaps just to get the thing attached.

Custom undercarriage fixes both ends of that problem. It starts with the ground your machine touches and ends with an interface that bolts on without modification. No field fixes. No compromise geometry.

Site terrain drives our design. Adjust ground pressure, shoe width and frame for your slope, soil and load. Resists sinking and spinning, reduces track shoe and roller wear.

It arrives ready to bolt on. Mounting holes, connection height, and hydraulic ports are made to your host machine's drawings. No cutting, no welding on site, no rework before the machine earns its first hour.

Less fitting time means a faster start. Installation work that would normally eat into your schedule is done before shipment, which shortens the path from delivery to production and removes a common source of early failure.

Fully adjustable undercarriage specs. Tune width, ground pressure, clearance, gauge and speed. Engineered to prevent sinking and keep your load safe.

Every published figure is measured and verified, never inflated. Confirmed orders ship with formal technical datasheets and drawings-ready for your machine design, registration, and acceptance checks.

More model specifications

The main beam and track frames are built from thick high‑strength alloy steel. Critical welds are robot‑executed for reliable resistance against twisting and cracking under harsh operating conditions.

Track rollers, idlers, drive sprockets and track shoes all go through quench‑and‑temper heat treatment for excellent wear resistance. The powertrain is precisely load‑matched to lower impact wear and cut downtime from component replacements.

Some factories build everything from farm trailers to conveyor frames, and the undercarriage is just another line item. We've stayed on steel track undercarriages for drilling rigs, piling machines, and specialty equipment - long enough that our engineers spot load and ground-pressure problems before they reach the drawing board.

From design and cutting, through welding, machining and heat treatment, all processes up to final inspection are completed in-house at our factory. No outsourced vendors cutting corners or delaying your production timeline. You talk directly to the engineers building your unit, and we can support prototype iterations and long-term OEM programs without a middleman in between.

In the swampy peat ground of Sumatra, a drilling rig was sinking before it ever reached the bore point - we delivered a steel track undercarriage with wide floatation grousers, and the unit now walks across ground that used to swallow it. That same rig has come back for repeat undercarriage orders as the fleet grows, which says more than any spec sheet.

For a European exploration contractor, we supplied a compact crawler chassis for a narrow-rig mounted on a tracked carrier, and it has been in steady OEM supply ever since - same mounting pattern, same tolerances, order after order. If your project calls for an undercarriage proven on real terrain and backed by repeat buyers, send us your machine type and tonnage and we'll walk you through comparable references.

Heavy steel chassis take a beating on the water, so we treat the walking parts with rust oil and film, then lock the frames onto timber or steel cradles. You open the container and find it as it left-no dents, no paint loss, no rework.

We plan the loading layout around your container, strap everything down so it can't shift, and hand you the packing list and marks to go with it. FOB, CIF, whatever suits your freight arrangement-we work with it. Fewer surprises at the port, less time lost clearing customs.

How To Cooperate With Us?

Murphy Company started operations in 2022, but the team behind it had already built up over ten years of experience in construction machinery.

 

Every tracked chassis assembly we design begins with one straightforward question: how will this host machine actually perform on site? From there, track shoe width, chassis size, load capacity, travel speed, and supporting parts are all customized to your requirements. What you end up with is a tailor-made crawler solution ready for engineering, construction, and mining work of all kinds
