Tracked Undercarriage Assembly

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

Most undercarriage failures don't start with the frame. They start with a loose bolt.

A missing cap or a stretched thread lets dirt in, the roller shifts, and the mounting hole opens up. By the time you notice, it's not a bolt anymore-it's a frame repair. Our steel crawler undercarriages ship with hardware torqued and sealed, so the first thing your crew does is run it, not retighten it.

Drill rigs, crushers, roadheaders. Rock, slurry, or coal dust.

We build the complete assembly around your mounting pattern. Q345B beam, hardened rollers, sealed idlers. No adapters. No re-drilling on your side. If it crawls on steel, the chassis logic is the same-only the numbers change.

Send tonnage and bolt layout. We'll tell you what fits.

Steel systems from 20 to 80 tons usually have reference dimensions ready to adapt. Larger goes through dedicated engineering. Replacement rollers and idlers available after the sale. The quote costs nothing.

Every undercarriage quote assumes something about how you work. The trouble is, most suppliers never ask. They quote the same frame, the same rollers, the same pitch - then leave you to discover the mismatch in the field.

Field mismatch has a way of showing up where it hurts most. A machine that won't track straight. A chain that keeps climbing off the idler. Small annoyances that quietly become repair bills.

Custom undercarriage begins by asking the questions a standard quote skips. What ground do you run on? How often do you turn? How hard do you load the machine? Answer those honestly, and the track system stops being a gamble.

Engineered for harsh environments, our steel tracked undercarriage offers great load capacity and wear resistance. High-strength alloy steel, fully welded reinforced frame.

Modular component design enables fast track and roller replacement in the field, drastically cutting downtime and lowering total cost of ownership for overseas operators. With customizable track gauge, width, and load capacity, it can be seamlessly integrated with a wide range of host equipment-from mining machinery to construction equipment that utilizes tracked undercarriages.

Prototype undercarriage and production undercarriage should share the same design language. We build your first track chassis to the drawing you'll scale later, so moving from a test unit to a production run doesn't mean starting over.

Short runs & one-off builds welcome. Hydraulic or electric drive available. Single units receive identical drawing review and quality checks as bulk orders. No compromise on materials and welds for your prototype. Send the spec, and we'll confirm what we can build.

TYPE D/ Rotating shaft type

TYPE E/ Prefabricated (upper flange)

More model specifications

Idle equipment from mismatched chassis costs your operation money each day. Suitable for a wide range of mining machinery, excavators, drill rigs, crushers, and auxiliary equipment for construction machinery. Fitment prioritized from the start. We verify mounting dimensions and load profiles upfront to avoid on-site rework.

Share your equipment, attachment weight and site terrain. We tailor chassis recommendations upfront. Get the fit right from the start to skip returns, rework and downtime.

Low-cost undercarriage systems often end up costing you more by the end of the first operating season. Common issues include weld cracking in areas subject to concentrated loads and uneven wear on track rollers; the resulting downtime will gradually "eat away" all the money you thought you had saved.

We ask about your machine and the ground before we quote anything. Track frame thickness, roller arrangement, and drive sizing follow from that. Drawings go to you for sign-off before production, not after.

Once it's built, we don't hand you a manual and vanish. Mounting gets confirmed with you directly.

Our factory features a comprehensive production chain-encompassing steel cutting, precision machining, robotic welding, heat treatment, and assembly-which allows us to maintain full control over the entire manufacturing process of our tracked undercarriages and ensures consistent, reliable quality for every product. CNC machining + automated welding, multi-point quality checks for reliable crawler undercarriages.

Over 10 years manufacturing experience. Optimized track design & materials for global market demands. Reliable undercarriages with on-time delivery for construction, mining & agriculture industries. We offer flexible OEM/ODM services, rapid sample development capabilities, and a professional export support system, making us a trusted, long-term partner for overseas buyers.

In Saudi Arabia, quarry teams pushing machines through sharp limestone and punishing heat keep losing sprockets and chain long before their time - the abrasive dust gets into everything and the sun does the rest. We build steel track undercarriages with hardened sprockets and sealed rollers that shrug off that combination. If your undercarriage is failing faster than your maintenance schedule expects, let's look at your duty cycle together.

In the Philippines, island job sites mean salt air, uneven volcanic ground, and equipment that has to be moved between locations constantly. Crews there tell us the track frame takes a beating during transport as much as during work. Our crawler chassis is built with reinforced mounting points and corrosion-resistant finishes for exactly that reality. Describe your site conditions and how your machines get moved, and we'll spec the undercarriage around both.

We take photos of every undercarriage before packing and loading, capturing straps, bracing blocks and shrink wrap. You get full visibility of everything going into the container. Should any detail not meet your expectation, we make corrections before container sealing. All photos and packing records are saved for your reference, easy to access whenever you need to check shipment details.

Shipping damage usually traces back to poor bracing, not bad luck. Ours gets blocked against the container walls and checked twice before departure. Tell us your port & machine model for custom packing solution. Custom bracing to reduce vibration and shifting in ocean shipment.

How To Cooperate With Us?

 

Murphy Company began operations in 2022, though the team behind it had already accumulated more than ten years of experience in construction machinery.

 

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