Track Undercarriage Assembly

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

Steel Track Crawler Drive Systems Undercarriage. Not a rubber compromise.
Drill rigs, exploration units, tracked carriers-we build the chassis they sit on. Mud, rock, mountain grade, mine haul roads. Q345B frame, sealed rollers, induction-hardened sprockets. It's the difference between a base that survives the site and one that becomes a maintenance line item.

Give us the tonnage and bolt pattern. We do the rest.
From 3 to 200 tons, every assembly is matched to your machine's mounting layout. Track frame, lower frame, travel base-fabricated as one unit. No adapters. No re-drilling. The structural core is a proven design; only the interface is built to your drawing. Custom without the custom wait.

Quote first. Commitment later. Spares after.
Steel systems in the 20 to 80 ton band often reuse existing frame dimensions. Larger tonnages go through dedicated engineering. Replacement rollers and idlers stay in stock. The proposal costs nothing-and neither does the conversation that comes before it.

A Tracked Chassis System that suits the site, not just the machine. Steep ground, soft footing, tight access - the load path and ground contact are worked out around where the equipment will actually run. High-strength steel holds its form under load, so the track stays planted through long shifts instead of digging in or losing grip.

Your drawings guide our build. Hole layout, mounting height and hydraulics match your host machine interface. Ready-to-fit delivery cuts on-site fabrication work.

 Assembly time is time you get back. Work that would otherwise happen on site is finished before the Steel Track Undercarriage Component leaves the workshop. That shortens the gap between delivery and first operation, and it keeps improvised fixes out of the commissioning process.

One Track Steel Track Undercarriage Chassis platform, many kinds of machines on top. Drilling rigs, exploration units, tracked carriers, compact drills, solar piling equipment, and geological survey tools can all sit on a crawler base we build to order, across a broad range of machine weights. You are not limited to whatever frame a catalog happens to stock.

Your original design stays fully yours. Submit drawings, bolt pattern & hydraulic routing. Custom mounting interface for your host machine. For new builds & retrofits. Dimensional checked before shipment to avoid fitment issues.

What you see in the spec sheet is what we measured. Order confirmed, and the technical data sheets and drawings travel with the shipment-handy for your own design work, filings, and sign-off.

Before anything is cut, our engineering team runs the numbers on your load case and host machine drawing - bearing pressure, roller arrangement, frame structure, mounting holes. What comes back is a CAD layout you can review, including entirely new Steel Track Crawler Track Frame Assembly concepts when the standard range doesn't cover it.

 Order size doesn't decide whether you get attention. A single prototype and a recurring OEM program move through the same machining and inspection steps, with lead times we commit to up front. That's the arrangement equipment brands stay with.

The structural backbone uses alloy steel plate selected for thickness, not low cost. Fixtures lock all components in place during robotic welding. The frame then undergoes heat treatment to relieve internal stress - stress that would otherwise cause cracking months after deployment. This is what enables our steel track running gear assembly to carry heavy loads and endure rough terrain without deformation.

Plenty of machine shops treat a crawler undercarriage as a side job - weld a frame, bolt on some rollers, call it done. We don't. Steel track bases for rigs, piling equipment, and off-road machinery are the only thing we do, and that focus shows up when a customer brings us an awkward load case or a ground condition nobody accounted for.

 Nothing on your order gets handed to an outside shop. Structure design, cutting, welding, machining, heat treatment, inspection - same building, same team, start to finish. That means prototype changes move fast, OEM programs stay on schedule, and the engineer you email is the one who actually built your chassis.

Long before steel is cut, your machine's weight, the ground it works on, and the mounting pattern you need all land on an engineer's desk. Ground pressure and load capacity get checked first, then a drawing comes back to you for approval. Everything is agreed on paper, which is exactly where rework gets killed.

On the floor, every stage is measured against that same drawing, and the finished Crawler Chassis Assembly runs a load test before it leaves. Inspection records go out with the unit, along with updates as production moves. What shows up at your door is ready to mount, not ready for another round of emails.

On a mountain access road in Sulawesi, a crawler carrier hauling exploration equipment kept losing traction on wet, loose scree - our steel track undercarriage with aggressive grousers and sealed rollers got it climbing where rubber simply couldn't. The operator has since ordered additional units as their survey fleet expanded, and we still supply the same mounting configuration.

A Middle East piling contractor first took a single crawler chassis as a trial build; after the machine survived a full season on site, the order turned into ongoing OEM supply for their tracked piling rigs. That progression - sample, trial, repeat - is the pattern we're used to. Share your machine type, tonnage and ground conditions, and we'll point you to references from the same region and application.

The parts that actually move-sprockets, rollers, idlers-are the ones that suffer most in transit, so they get rust oil and protective film before anything else happens. Then the Complete Steel Track Undercarriage goes onto timber or steel cradles, with each section blocked so it can't lean into its neighbour. Salt air and rough handling are the two things that ruin a delivery; we plan for both.

On the loading side, we figure out the layout around your container instead of forcing it in, and tie everything down so it stays put across the ocean. Paperwork comes with it-packing list, shipping marks, product documents-and we're fine working under FOB or CIF depending on how you'd rather arrange things. The point is that your team isn't chasing problems after the container lands.

How To Cooperate With Us?

Murphy Company launched operations in 2022, yet the team behind it had already gathered more than a decade of construction machinery experience.

 

Every tracked chassis assembly we design starts with one simple question: how will this host machine actually perform on site? From that point, track shoe width, chassis size, load capacity, travel speed, and supporting parts are all customized to your requirements. What you end up with is a tailor-made crawler solution ready for engineering, construction, and mining work of all kinds.
