Heavy Duty Steel Track Undercarriage Roadheader

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

This undercarriage is engineered to suit a broad range of carrier models and job‑site environments. Key parameters-including track length, width, shoe thickness, gauge, and drive configuration-can all be adjusted to meet your equipment specs and site conditions.

It offers a dependable foundation for OEMs, system integrators, and global distributors in need of rugged, heavy-duty tracked chassis with flexible layout options.

Built for demanding applications, our excavator crawler chassis handles heavy loads with ease. Steel track configurations provide steady mobility on muddy, sandy, rocky and uneven terrain. Built for sustained high-intensity operation, the system delivers consistent reliability with minimal maintenance demands.

 

Its low-profile design enables installation under compact drill rigs where standard undercarriages cannot fit, eliminating the need for customer-side structural redesign.

The open-center structure reserves ample internal space for your on-board components, accommodating drill feeds, hydraulic hoses and all routed equipment.

Custom mounting plates tailored to your specific bolt pattern for seamless installation
Precision weight distribution prevents sagging and tilting, even with offset loads
Base-style open framework retains your original equipment layout while supporting stable track performance

Our diverse undercarriage configurations provide dependable traction over muddy, soft and uneven ground. They keep drill rigs, excavators and other tracked machinery operating productively in the toughest field conditions. Less slippage and fewer interruptions contribute to steady, predictable performance on site.

Customization highlights include:
Final drives – choose between hydraulic or electric motor options.
Frame joining – connect the intermediate beam to side frames either by full welding or bolted construction.
Sealed undercarriage rollers: Floating oil seals remove the need for routine lubrication over long service periods.
Track tensioning mechanism: Grease-charged cylinders paired with damping springs enable fast, trouble-free track adjustment.
Track protection: Optional chain guards can be fitted to boost component durability.
Track shoes – select high-strength alloy steel or wear-resistant rubber compounds for improved impact resistance and extended operating life.

Our factory adheres to rigorous production protocols to ensure precision and consistent quality across deliveries, with inspections performed at every production stage.

Manufacturing starts with laser cutting, CNC bending, and precision machining-building in tight tolerances and uniform quality from the very beginning.

In the final assembly phase, each bolt is torqued to required specifications and treated with thread-locking adhesive. This modest design upgrade delivers tangible benefits: more robust joints and longer intervals between routine servicing.

Murphy's engineering team focuses on chassis adaptation and custom undercarriage solutions for heavy-duty machinery. We deliver reliable undercarriage solutions for standard construction equipment, professional drill rigs and purpose-built tracked vehicles, serving a wide range of excavation, drilling and crushing applications. Each load-bearing component and hydraulic drive system is precision-designed to fully comply with the unique technical specifications of every machine model.

We tested these wide track pads through an entire rainy season on clay-rich job sites - and never once needed a tow truck.
On rocky terrain, the wider track shoes cushion impacts from sharp rock fragments. This reduces chipping and cuts downtime between work shifts.
Even on constrained urban job sites with curbs and leftover rebar, the expanded footprint holds the machine steady without damaging paved surfaces.
Whether navigating mud, rock, or compacted gravel, you can rely on the same undercarriage - no part replacements needed when switching job sites.
The stability gain is instantly apparent on slopes. The machine maintains a flatter stance and will not dig aggressively into the ground.

Our custom-engineered crawler chassis provides stability for drilling rigs on frozen or uneven terrain, delivering dependable traction and solid load support even under extreme cold conditions.

Murphy is one of a limited number of manufacturers capable of in-house production of tracked undercarriage assemblies, with a sharp focus on R&D and manufacturing for construction machinery. Drawing on deep expertise in both track systems and hydraulic controls, we supply undercarriage assemblies customized to varying weight categories, dimensions, structural layouts, and site-specific application needs.

1.Open-frame layout simplifies piping, wiring and maintenance; no major machine disassembly required

2.Reinforced side beams (not simple box sections) carry loads and reduce stress on your host equipment

3.Flexible spare parts: single track pad or full roller sets available, fast quotation & delivery, no minimum orders

4.Manual plus live technical support. Share photos for troubleshooting, we guide you through installation

5.Custom-drilled top plates built to your specs, not generic templates; mount components at your preferred positions
