Rotary Drilling Rig Undercarriage

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

Buyers often ask for a price before they ask what the undercarriage has to survive. That order is backwards. The quote only means something once the ground, the load, and the duty cycle are on the table.

 

A standard track frame can look fine on paper and still be wrong for your machine. Mounting points don't line up. Ground pressure runs too high for soft terrain. The oscillation range fights every slope you work on.

 

Every custom undercarriage is engineered around your application, not a standard catalog. Share your machine's function, working environment and operating intensity, and we'll deliver a track system that fits perfectly on the first try, no repeated adjustments required.

High-manganese steel is used across all wear-prone areas. Track shoes, drive sprockets, idlers and rollers are forged from this hardened alloy and undergo integral quenching treatment. Withstands crushed rock & ore slag. Resists cracking and flattening vs softer material alternatives.

Sealing is designed as a complete system, not an afterthought.Dual floating seals for all rotating cavities. Block slurry, dust and mineral water to retain grease and extend service life.

An integrated hydraulic parking brake works alongside a dedicated balance valve, so the chassis holds its position on grades, during idle, and through static operations like drilling.

Undercarriage bears full load for all tracked equipment. Chassis for excavators, drill rigs, crushers, trenchers, tracked carriers, crawler bulldozers, track loaders & tracked material handlers. Ideal for construction, mining, agriculture.Fitment starts with your machine and how hard you run it. Send those details over, and we will match the chassis to your work.

A crawler undercarriage only works when it fits the machine it carries. Custom mounting layout, track gauge & load points. Integrated chassis system rather than separate loose parts.

Hydraulic / electric drive, steel / rubber track. Options tailored to your ground and duty cycle. Tell us what the equipment does, and we will shape the undercarriage around that job.

All components are manufactured to OEM installation dimensions. Share your machine model, and we'll match the proper specifications for your build.​​​​​​

Details：

Each track frame goes through a load test before it leaves the line, so what arrives at your site has already carried weight. The pivot joint is greased and sealed at assembly, which keeps the oscillation point clean through muddy ground. Rollers & idlers machined as matched sets, no cross-batch mixing. Get matched undercarriage configuration for your daily operation.

Customization Process：

Every custom undercarriage starts with your machine, not our inventory. Tell us what you're running and where-we'll work out the track frame, roller layout, and drive setup from there. Drawings come to you for review before we cut anything. Production only moves once you're satisfied with the design. Then we confirm the mounting details together, so it fits your carrier without surprises.

Our own steel cutting, our own machining, our own assembly line - nothing gets outsourced to a third party you can't audit. Fixtures and tooling stay under our roof, so custom undercarriage work doesn't sit waiting on someone else's schedule. Weld quality and heat treatment are controlled on site, batch after batch.Parts built from original drawings, available years after production. Send machine & tonnage for fast fitment check.

A contractor running compact excavators on wet clay found standard rubber tracks sinking and spinning. We supplied a wider steel track undercarriage with mud-relief grousers, and the machine stopped digging itself in. Overseas, a demolition crew working on broken concrete kept losing track tension on their crawler chassis. Our reinforced track frame with heavy-duty recoil springs held alignment through the whole job.

Looking for an undercarriage that matches your ground conditions instead of fighting them? Tell us your machine and application - we'll recommend the right crawler undercarriage and send a quote.

Export-ready packing for steel track undercarriages: fumigated wood, steel strapping, and moisture-proof wrap go on every unit before it touches a container. Custom blocking & bracing for ocean shipment. Packing adjusted to container size. Suitable for humid or dusty destination ports.

 Tell us the port, and we'll prep accordingly. Send your undercarriage specs and we'll come back with a packing and freight plan.

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.

 

Every tracked chassis assembly we design starts with one simple question: how will this host machine actually be used on site? Track shoe width, chassis size, load capacity, travel speed, and supporting parts are all tailored to your requirements. What comes out of that process is a custom crawler solution built to handle engineering, construction, and mining work of all kinds.
