Rotary Piling Rig Undercarriage

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

3 to 200 tons. Built around your machine, not the other way around.

Send us the mounting dimensions and duty cycle. We engineer the crawler undercarriage to bolt straight onto your drilling rig, crusher, or platform. Steel and rubber track systems, Q345B main beams, heat-treated rollers. No adapter plates, no guesswork.

Custom doesn't have to mean slow or expensive.

Structural modules stay standard, interfaces stay fully custom. Lead times in weeks, not quarters. Nabtesco, Brevini, or our own travel drives-your call. From compact crawler chassis to heavy-duty steel track systems, the engineering logic is the same.

A weight figure and a rough sketch are enough to start.

Steel undercarriages up to 80 tons and rubber systems up to 30 tons often have reference parameters we can adapt quickly. Larger capacities go through custom engineering. The proposal costs nothing. The conversation costs nothing.

Most undercarriage failures don't start with a broken part. Proper track design is application-specific. A 20t drill rig on soft ground needs different track geometry and ground pressure from a 20t crusher on uneven rock. Off-the-shelf undercarriage forces you to compromise-and the wear shows up months later, not on the spec sheet.

The real cost isn't the replacement parts. It's the downtime. A 30-ton machine with a failed track group can burn $25,000 to $40,000 in parts alone, plus three weeks of lost production. Planned sprocket replacement costs a fraction of that. Custom undercarriage lets you set the wear cycle on your terms, not the manufacturer's.

Whether you're building drilling rigs, mini excavators, or agricultural equipment, the undercarriage is the one system you can't afford to treat as an afterthought. Tonnage ratings from 0.5 to 150 tons exist, but the right number for your machine is the one that keeps your rollers, sprockets, and chains wearing evenly together. That's not a catalog spec. That's a conversation

 We customize crawler undercarriage systems ranging from 3 tons to 200 tons. Dimensions are determined by your actual operating conditions - ground type, gradient, and whether the machine travels or works in a fixed position.

We offer both rubber and steel track options. The structural steel beam and final drive selection are matched to your duty cycle. Share your machine type and application, and we will confirm the suitable track width, track gauge and ground clearance for you.

Our crawler undercarriage systems are built to fit a broad range of tracked equipment, from compact mini excavators and skid steer loaders up to 80-ton class drilling rigs and crushers.

Whether you operate compact utility machines, mid-size excavators, or heavy-duty equipment in construction, mining, or agriculture, we manufacture chassis that match your machine's specific track width, pitch, and load capacity.

If you are looking for OEM-compatible undercarriage replacements or a fully custom track system, just tell us your machine model and operating weight-we will take it from there.

From 500 kg utility carriers to 200-ton heavy crusher bases, our crawler undercarriage systems are built around your machine's mounting points, track length, gauge, and load distribution rather than forcing you into a stock frame.
Hydraulic final drives deliver consistent torque for drilling and excavation. Electric drives offer low-noise, zero-emission operation. Both systems share a compatible mounting platform for flexible application.

Our steel tracked chassis is built to custom drawings matching your bolt pattern and hydraulic flow. It supports direct bolt-on installation without on-site modifications. Send us your payload and application, and we'll offer a matching layout.

More technical parameters

 Engineered around a Q345B box-section beam, this crawler undercarriage delivers the structural rigidity OEM buyers expect from a 3 to 200 ton class unit, with a load capacity range covering 3 to 200 tons for steel tracks and 0.5 to 10 tons for rubber tracks.

Should you require 3D drawings or custom track width adjustments prior to order confirmation, our engineering team can deliver these promptly.

Murphy's engineering team handles chassis adaptation and custom undercarriage work for heavy-duty machinery. We start by reviewing your load capacity and site conditions, then design an undercarriage with stability tuned to your application.

Getting a custom crawler undercarriage that actually fits your machine starts with one honest conversation-tell us the tonnage you're working with and the ground it'll run on, and we'll tell you whether steel or rubber tracks make more sense for your 3-ton mini digger or your 200-ton drilling rig.

From there, our engineers run load calculations and send you a 3D drawing for approval before a single piece of steel gets cut. Only after you've signed off on the prototype do we move to production, and we keep talking through the final mounting details so the chassis bolts up to your upper structure without a fight.

 Heavy-gauge steel fabrications, in-house machining of every idler and roller, and full-penetration welding on the main frame - that's what separates a undercarriage that survives a decade in a quarry from one that fails in eighteen months.

We build the complete crawler undercarriage in our own facility, from steel plate to assembled unit, so tolerances stay tight and lead times stay honest. Whether you need a 3-ton rubber track undercarriage for a mini excavator or a 50-ton heavy duty crawler chassis for a drilling rig, the same QC process runs on every unit before it ships. Ask for a sample inspection report - you'll see exactly what we mean.

Canadian drilling contractors operating on swampy and permafrost terrain require a 30-ton-capacity tracked chassis. Their original track frames suffered persistent cracking over months of service. We engineered a custom steel tracked chassis with reinforced idler mounting and sealed rollers, achieving reliable performance with more than 4,000 hours of failure-free operation.

Quarry jaw crushers on rubber tracks waste shift time on frequent track tension adjustments

Heavy-duty chassis with upgraded recoil springs cuts downtime by ~70%

We quote 3–200 ton tracked systems tailored to your real site conditions and installation setup

Every unit ships on fumigated wooden pallets with heavy-duty steel strapping and moisture barrier wrap, loaded into 20ft or 80ft containers for 3–200 ton capacity steel track undercarriages-no rust, no shifting, no surprises at destination.

We provide seaworthy packaging for oversized and heavy-duty crawler undercarriage orders. Packages feature reinforced steel framing and shock-absorbent filling to withstand rough handling at ports.

Murphy Construction Machinery (Shandong) Co., Ltd.

We engineer tracked chassis assemblies around the actual working conditions of each host machine.
