Crawler Undercarriage For Underground Drill Rig

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

Steel track undercarriages for drill rigs, excavators, crushers, and roadheaders. 3 to 200 tons

Share your load requirements and mounting layout. We manufacture the crawler chassis as a full assembly, consisting of track frame, lower frame and travel base, enabling direct bolt-on fitment to your host machine.

Equipped with hardened rollers and sealed bearings, these chassis are engineered for rock and coal mining applications.

The structural core stays consistent across sizes. Only your interface changes. That's how a 120-ton drilling rig base avoids a six-month lead time. Travel drives matched to your hydraulic flow.

Send a sketch. We'll tell you what fits.

Steel systems from 20 to 80 tons often share reference dimensions we can adapt fast. Larger goes through dedicated engineering. No charge for the proposal.

A custom undercarriage isn't about building something exotic. It's about matching the track system to the ground it actually touches. Soft soil, hard rock, steep slopes-each one punishes a different part of the undercarriage. Get that match wrong, and the machine tells you soon enough.

Mass-produced standard chassis are built for generic use. Same-weight machines can have very different track wear rates. The root cause is poor fit, not poor quality.

The fix isn't a bigger track or a heavier frame. It's getting the geometry, ground pressure, and roller spacing right for your working conditions. When those align, wear evens out, downtime drops, and the machine stops eating your maintenance budget.

If it runs on tracks, our undercarriage can be built for it. Core undercarriage parts universally applied across construction, mining and agricultural machinery.

We confirm fitment according to machine class, track type and mounting pattern, eliminating guesswork in the design process.

Share your machine model and working conditions, and we will custom-build the chassis to match your application.

Every crawler undercarriage we quote begins with your mounting drawing, not our standard frame. Track gauge, center distance, and bolt pattern are set by your machine. Hydraulic or electric drive, your call - both mount on the same platform. Rubber or steel track, whichever suits your ground and duty cycle.

Tell us the equipment and the working condition, and we will match the undercarriage to it. No oversized catalog, no guesswork.

Be used in a wide range of industries.

 

 

 

 

 

OEM-dimension undercarriage for 3–200 t excavators, dozers, and drill rigs. Sealed track chains, forged rollers, reinforced idlers-bolt-on ready. Send your model and tonnage for exact matching.

More product parameters

Cast steel sprocket with hardened tooth profile for even 360° wear. Bolt-on track guards enable partial replacement, no full assembly disassembly required.

The undercarriage frame is jig-welded in a single pass, which keeps the mounting hole alignment within tolerance for your OEM interface.

 Send us your mounting dimensions and we will confirm fitment within 24 hours.

Steel plate enters as raw material, leaves as a finished undercarriage - all under one roof.

Our welding line runs full-penetration seams, not tack-and-grind shortcuts. Heat treatment is done in-house, so hardness depth stays consistent batch to batch. Every 10-ton and 80-ton crawler chassis gets a load test before crating.

Send us your mounting drawing, and we'll come back with a quote and a production schedule.

Rubber tracks on a compact loader kept snapping pins in Baltic winters - cold makes standard seals brittle. We switched that fleet to a steel track undercarriage with low-temperature rollers and boron-alloy chain, and it has run three winters without a pin failure.

A Middle East contractor moving a 25-ton crawler chassis across hot sand was cooking its final drives; our vented track frame and upgraded sprocket design dropped gearbox temperatures by 20°C. Need a 10-ton or 60-ton undercarriage built around your duty cycle, not a catalog number?

 Send us your mounting drawing and load data - we'll come back with a real quote, not a brochure.

Steel track undercarriage leaves our floor wrapped in VCI film and strapped to fumigated skids, then braced inside the container so nothing moves in transit.

We load 20ft, 40GP or 40HQ depending on your tonnage-3 to 60 tons, no wasted freight. Rollers and sprockets are boxed separately with desiccant for humid ports.

Send your model and destination port, and we'll quote the packing plan within 24 hours.

How To Cooperate With Us?

Murphy Company opened its doors in 2022, but the people behind it had already put in over ten years in the construction machinery business.

 

Every tracked chassis assembly we design starts with one question: how does this host machine actually work on site? Track shoe width, chassis dimensions, load capacity, travel speed, and supporting parts are all up for customization based on what each customer needs. The result is tailor-made crawler solutions that find their way into engineering, construction, and mining work of all kinds.
