Retractable Undercarriage For Rotary Drilling Rig

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

A lot of undercarriage problems trace back to one decision made too early. Someone picked a track frame because it was available, not because it was right. Months later, the machine is eating sprockets and nobody remembers why.

 

What makes this expensive isn't the parts. It's the rhythm it creates. Replace or adjust parts, but the machine still won't settle into stable operation. Maintenance becomes a habit instead of a schedule.

 

Custom undercarriage breaks that cycle. It starts with how your machine actually works, not how a catalog says it should. The payoff isn't just longer part life. It's a machine you stop worrying about.

Switching undercarriage suppliers shouldn't mean reworking your machine. We pick up from your existing mounting points and track layout, so the new frame drops in where the old one sat - no redrilling, no adapter plates.

A late undercarriage holds up the whole build. We quote against your equipment type and working condition, keep hydraulic and electric drive options open, and confirm the fit before anything ships. Send the application; we'll tell you what works.

An ill-fitting undercarriage equals costly downtime and wasted investment.Crawler chassis for excavators, drill rigs, crushers, trenchers and tracked carriers. Our custom-engineered steel track undercarriages fit your host machine precisely to prevent alignment issues and premature component wear. Machine fitment confirmed pre-production. That way you are not stuck with something that looks right and runs wrong.

Share details about your machine, working attachments and site ground conditions. Track, mounting and load specs tailored to your needs. All designs pass load simulation pre-production for stable on-site performance. One conversation up front saves you weeks of downtime later.

Rubber and steel track undercarriages for compact excavators, dozers and drilling equipment. Sealed chains, heavy-duty rollers, reinforced idlers - engineered for OEM fitment. Both versions offer extended service life, with fast component replacement to cut your on-site downtime. Tell us your machine and we'll spec the right undercarriage.

More model specifications

Undercarriage tailored to unlock your machine's full potential. Adjustable track length, shoe width, gauge and drive type. Load analysis ensures safe handling of heavy site loads. Mounting points are matched so the chassis drops in without reworking your main frame.

Hydraulic / electric / radio remote control options. Travel system configurable for standard hydraulic, electronic or wireless remote operation. That means the same undercarriage platform works across different machine types and different job sites.

Modular construction, not fixed design. Easy adjustments for track width and roller layout. You get a chassis that matches your equipment and your working conditions, rather than one you have to design around.

On-site track frame cracks bring costly downtime. All weldments undergo stress relief after fabrication, no direct shipment from jigs. This process removes internal welding stress and greatly reduces the risk of frame cracking under heavy cyclic loads.

The recoil system is fully assembled and cycle-tested prior to installation in the frame, so you won't encounter a binding spring out on the job site. If your current supplier leaves you chasing answers after delivery, send us your drawings and see how we handle it before the order.

Lead times that slip, parts that don't line up, a supplier who goes quiet after the deposit - you've probably dealt with all three. We keep cutting, machining, and assembly under one roof, so nobody else's schedule decides when your undercarriage ships.

Send us your mounting drawing or machine model. We'll come back with fitment confirmation, a realistic lead time, and a price that won't move after you pay. No middlemen, no surprises.

In Indonesia, contractors running coal haulers on soft, rain-soaked ground watch rubber tracks dig in and stall the whole cycle. We build steel track undercarriages with wide, self-cleaning grousers that keep those machines moving when the ground turns to soup. If your site loses hours to stuck equipment, that's the conversation to start.

In the UAE, the problem flips - heat and fine sand grind away at idler seals and final drives before their time. Our sealed rollers and vented crawler chassis handle that grit without cooking the gearbox. Tell us where your machines work and what keeps failing, and we'll spec the undercarriage around that reality. 

Most undercarriage failures trace back to one thing-it was never sized for the machine it went on. Too much load on the rollers, a frame that flexes where it shouldn't, and you're back to replacing parts long before you should be. Our custom chassis design balances load distribution and limits frame deflection to extend your track system's service life.

No one-size-fits-all designs. Track frame, roller count and drive setup tailored to machine weight, operation and ground conditions. Drawings approved before steel cutting.

Send us what you're working with and we'll take it from there.

Your steel track undercarriage gets wrapped, strapped and blocked before it ever sees a container. Fumigated timber and moisture barrier film come as standard packaging. Rust causes more equipment damage than harsh ocean transit. This protective packaging keeps steel components dry during sea shipment and storage at your yard.

Packaging customised for your destination & transport. Built for humid ports and long inland haulage. You get updates from loading to departure, so there's no guessing on your end. All chassis are secured with heavy-duty packaging to avoid transit damage during ocean and land shipments.

How To Cooperate With Us?

 

Murphy Company opened for business in 2022, yet the team behind it had already spent more than a decade in construction machinery.

 

Each tracked chassis assembly we design kicks off with a single question: how will this host machine really be used on site? From there, track shoe width, chassis size, load capacity, travel speed, and supporting parts are all tailored to your requirements. What you get in the end is a custom crawler solution built to take on engineering, construction, and mining work of every kind.
