Tracked Undercarriage for Excavator

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

A full undercarriage consists of several key components, each with its own job:

Tracks：directly contact the ground and provide traction.

Drive sprockets：driven by the hydraulic motor to turn the tracks.

Idlers：located at both ends of the track frame to guide the track and keep it running straight.

Track rollers：carry most of the machine's weight and are the main load‑bearing wheels.

Carrier rollers：support the upper run of the track to prevent it from sagging.

Track frame：the backbone of the entire undercarriage, tying all the components together.

Track tensioning system：adjusts track tightness to prevent derailment.

Travel motor：supplies the power for moving the machine.

Compared with wheeled undercarriages, tracked ones offer clear benefits, especially in demanding conditions.

Superior terrain adaptability – this is where tracked undercarriages really stand out. They handle soft or uneven ground – swamps, riverbanks, mud, gravel – with ease, places where wheeled machines often have trouble getting into.

High traction and grip – the wide track plates give a large footprint, which translates into strong grip. That allows the machine to climb steep slopes and push through deep mud without losing traction.

Very low ground pressure – the machine's weight is spread across a large track area, so the pressure on the ground is minimal. This prevents sinking and also protects paved surfaces or softer ground.

360° spin turns – by running the two tracks at different speeds, the machine can turn on the spot, rotating a full 360°. That makes it highly manoeuvrable in tight spaces.

Excellent stability – a low centre of gravity and a wide track stance give the machine great side‑to‑side stability. This reduces the risk of tipping when working on slopes or lifting heavy loads.

Based on the size of the customer's equipment, construction environment, load-bearing capacity, track width, and walking drive form, a one-to-one customized excavator track chassis complete set matching solution is provided. Supporting OEM and ODM OEM services, helping customers shorten equipment development cycles, improve overall operational stability, and enhance product market competitiveness.

The factory is equipped with a dedicated engineering research and development team, deeply engaged in the field of excavator track chassis matching. It can customize exclusive bearing parameters and hydraulic walking systems for different equipment working conditions such as excavation, drilling, and crushing, and the adaptability to working conditions far exceeds that of general chassis products. With years of experience in mass production of heavy-duty chassis, we can provide mature and stable one-stop walking support solutions for various engineering equipment, drilling equipment, and special tracked machinery. The entire line adopts CNC precision machining and is equipped with a traceable quality control system throughout the entire process. The accuracy of batch products is unified and the performance is stable, which can efficiently undertake large quantities of foreign trade orders at home and abroad.

The standard rubber track is designed for everyday drilling operations where stability and smooth movement are important. Its balanced tread pattern provides good traction on different ground conditions while helping reduce surface damage during travel.

Chassis components are produced through laser cutting and CNC bending, ensuring tight dimensional tolerances and consistent part quality. Automated robotic welding creates uniform, strong seams while controlling thermal deformation to preserve structural integrity. Key mounting bases and locating holes are machined on a gantry machining center to guarantee precise assembly fit. The parts then go through shot blasting, automatic painting, and high‑temperature curing, giving them strong corrosion and rust resistance. Final assembly follows standardised procedures – all bolts are secured with thread‑locking compound and torqued to specification, preventing loosening during long‑term operation and ensuring reliable performance.
