Rotary Drill Crawler Track Frame Assembly

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

3 to 200 tons. Steel track systems built to your mounting points, not adapted to them.

You send the tonnage and the bolt pattern. We fabricate the crawler undercarriage to match-Q345B main frame, sealed rollers, hardened sprockets. No adapter plates. No re-drilling on your end. It arrives ready to bolt on and go to work.

You've been told custom takes a quarter. We don't work that way.

Structural modules stay standard across the tonnage range. Your interface stays fully custom. That means a 60-ton drilling rig chassis starts from a proven frame, not a blank sheet. You get weeks, not months. And the quote reflects a production unit, not a one-off weldment.

Send a weight figure and a mounting sketch. We'll come back with a matched proposal.

Steel track undercarriages in the 10 to 80 ton range often have reference dimensions we can adapt quickly. Larger goes through dedicated engineering. No charge for the quote. No charge for the conversation.

Not every machine needs a custom undercarriage. But the ones that do usually share one trait: the factory option was designed for someone else's job. A drilling rig working on 30% side slopes demands different load distribution than a crusher feeding on flat quarry floor. Cat's own engineering data shows undercarriage life swings dramatically based on application and operating speed-the same component can last years or months depending entirely on how it's used.

Here's the part most buyers learn too late. Undercarriage accounts for roughly 20% of a machine's purchase price but up to 50% of its lifetime repair cost. When you spec a standard unit for a non-standard application, you're not saving money upfront. You're financing someone else's compromise through accelerated wear on every component in the system.

For 20-ton mobile crushers, 15-ton anchor drilling rigs, or 8-ton agricultural harvesters, the difference between a catalog undercarriage and an engineered one comes down to a few millimeters of link height and a few degrees of oscillation. Those millimeters are what determine whether your sprockets and bushings wear at matching rates-or whether you're back on the phone ordering track groups twice as often as you should be.

Every undercarriage we ship starts with a load-bearing calculation, not a catalog number - track width, ground pressure, and drawbar pull are matched to your machine's real operating weight and terrain.

 Full in-house undercarriage assembly. All core components are integrated into one single unit, saving multi-vendor procurement and coordination work. Custom track configurations for soft soil, gravel and paved surfaces. No rigid standard templates - fully adapted to your actual working conditions.

When your jobsite demands reliable chassis performance for drilling rigs, crushers and trenchers, the undercarriage stands as the core structural foundation of your equipment, not a replaceable commodity.

We supply complete crawler undercarriage assemblies for construction, quarrying, forestry and agricultural machinery. Our product range covers equipment from 3-ton mini excavators all the way up to 50-ton and 200-ton heavy-duty platforms.

Full-spec compatible undercarriage parts and track conversion kits. Accurately matched track pitch, link count, roller size and final drive fit for excavators and drill rigs. Send us your equipment type and tonnage, and we will confirm fitment before you commit to an order.

Common undercarriage failures originate from factory mismatches - misaligned holes, delayed deliveries, and non-adjustable welded drive structures. We build rubber track chassis and steel crawler bases around your OEM mounting interface, so the bolt pattern, track gauge, and center distance match what your equipment already expects.

We offer both hydraulic and electric drive configurations on the same chassis frame, covering applications from 3–8 ton drill rig mini crawler bases to 20–100 ton mobile crusher platforms. This allows straightforward power unit swaps without full chassis redesign.

Instead of generic catalog solutions, we deliver custom layouts and accurate lead times based on your exact load conditions and mounting requirements.

More product parameters

Every weld of the crawler chassis is completed by robotic welding and inspected in accordance with ISO 3834 requirements. This strict quality standard enables us to offer a 12-month warranty for the undercarriage frame, with no tricky fine-print clauses.

The track tensioning system adopts a grease cylinder equipped with a visible stroke indicator. Field technicians in Saudi Arabia, Indonesia and other global job sites can check and adjust track tension directly at a glance, eliminating guesswork on site.

Tell us your machine's operating weight and ground conditions, and we will recommend whether a rubber track undercarriage or a steel track setup makes more sense for the application.

Custom-built undercarriage tailored to your machine and ground conditions, not off-the-shelf. We match roller count, chain pitch and frame gauge according to your actual operating weight and workload.

You'll see a CAD layout and a load rating sheet before tooling begins, so there's no guessing on whether it holds up in a quarry or a rice paddy. Once the drawing is signed, we cut, weld, and assemble to that spec, then walk you through the mounting points so the finished chassis drops onto your carrier frame without rework.

In-house full-process manufacturing: plasma cutting, CNC boring, induction hardening & alignment check. Tight tolerances on idler runout and roller concentricity beyond typical aftermarket assemblers.

Tell us the machine you're repowering - a 5-ton crawler carrier, a 30-ton drilling rig base, or anything between - and we'll match the mounting pattern, track pitch, and hydraulic drive interface without guesswork. If you want proof before committing, we'll send dimensional inspection sheets from a recent build of the same tonnage class.

A mine operator in Western Australia was burning through rubber track undercarriage assemblies every eight months on abrasive iron-ore ground, so we supplied a steel track undercarriage with hardened track shoes and lifetime-sealed rollers - that unit is now past 6,000 hours and still on its original chain.

Proven case: Precision-machined track frame eliminates alignment drift and sprocket wear for European mobile screener. Custom quotes for 15–40 ton undercarriages, tailored to your bolt pattern and load requirements.

Standard fumigated crates + VCI anti-rust packaging. Custom steel fixture fixation ensures stable transport and space-efficient 40HQ container loading.

For units shipped to humid Southeast Asian sites or dusty Middle Eastern worksites, we add extra desiccant and shrink wrap as enhanced protection. Corroded or misaligned chassis upon arrival can disrupt your entire construction season.

Share your equipment tonnage and destination port, and we will design a tailored packing plan for your shipment.
