YIJIANG manufactures custom steel track undercarriages for heavy-duty and specialized tracked machinery. Our crawler systems are engineered according to machine weight, operating conditions, required traction, track dimensions and upper-machine mounting requirements. Steel track undercarriages can be configured with hydraulic travel motors, track rollers, front idlers, drive sprockets, steel track chains, customized center frames and mounting structures. Applications include drilling rigs, mining equipment, mobile crushers, pile drivers, excavators, tunnel machinery and other heavy construction equipment.
A steel track undercarriage is a crawler chassis designed to support, propel and stabilize tracked machinery in demanding operating environments. Compared with lighter crawler configurations, steel track systems are commonly selected where high structural strength, impact resistance, traction and long-term durability are important.
YIJIANG designs and manufactures steel tracked undercarriages for both standard and specialized machinery. The complete system can be engineered around the customer's machine rather than forcing the equipment to fit a fixed undercarriage.
Depending on the application, the crawler system can include steel tracks, track rollers, front idlers, drive sprockets, hydraulic travel motors, track frames and a customized center frame or mounting structure.
Our existing projects cover different machine sizes and applications, including heavy construction equipment, drilling machinery, mining equipment, tunnel machinery and mobile crushers.

Steel track undercarriages are designed for demanding applications where high load capacity, durability, impact resistance and reliable traction are required. Their robust steel track system and structural components make them suitable for heavy machinery operating on rough, abrasive and uneven terrain。
| High Load-Bearing Capability | Load capacity & structural strength | Steel track undercarriages provide a strong supporting structure for heavy machinery. Track frames, rollers, track chains and structural components work together to distribute machine weight and operating loads across the crawler system. |
| Impact & Abrasion Resistance | Tough working conditions | Steel track components are well suited to environments involving vibration, impact and abrasive ground conditions. They can withstand contact with rocks, construction debris and uneven terrain, making them suitable for demanding construction, mining and drilling applications. |
| Traction on Rough Terrain | Traction & power transmission | The mechanical engagement between the drive sprocket and steel track provides reliable power transmission and traction. Track width, sprocket configuration and hydraulic drive can be selected according to machine weight, terrain and operating requirements. |
| Long-Term Durability | Service life & reliability | Steel crawler undercarriages are engineered for demanding operating conditions and extended service. Proper selection of track components, rollers, idlers and structural parts helps maintain reliable crawler performance under heavy-duty working conditions. |
| Steel Track Chain & Track Shoes | Steel track chains and track shoes provide the main ground-contact and traction system. Their configuration can be selected according to machine weight, terrain and required operating conditions. |
| Track Rollers | Track rollers support the steel track chain and transfer machine weight to the crawler system. Roller size and arrangement are selected according to load, track configuration and operating conditions. |
| Front Idler & Track Tensioning | The front idler guides the steel track and works with the tensioning system to maintain proper track engagement. Hydraulic or mechanical tensioning can be selected for different applications. |
| Drive Sprocket | The drive sprocket engages with the steel track chain to transfer power from the hydraulic travel motor. Sprocket design is matched to the track chain and drive configuration. |
| Hydraulic Travel Motor | The hydraulic travel motor provides driving power for crawler movement. Motor displacement, torque and speed can be selected according to machine weight, travel requirements and terrain conditions. |
| Steel Track Frame | The steel track frame supports the crawler components and connects the undercarriage to the upper machine. Its dimensions and mounting structure are engineered according to the equipment requirements. |
Machine Weight & Load DistributionThe undercarriage should match the machine weight, payload and center of gravity. Proper load distribution helps maintain structural stability and reduces excessive stress on crawler components.
Track Width & Ground ContactTrack width affects ground contact, stability and ground pressure. Track dimensions should be selected according to machine weight, terrain and operating requirements.
Mounting InterfaceThe mounting interface connects the crawler undercarriage to the upper machine. Mounting dimensions, bolt patterns and structural requirements should be matched to the equipment.
Track Gauge & Overall DimensionsTrack gauge and overall dimensions affect machine stability, transport width and installation space. These dimensions can be engineered according to equipment requirements.
Ground ClearanceGround clearance provides space between the undercarriage and the working surface. The required clearance depends on terrain, obstacles and the machine's operating environment.
Designed for demanding mining environments where high load capacity, traction and durability are required.
Provides stable crawler support and reliable mobility for drilling equipment working on uneven or challenging terrain.
Suitable for mobile crushing equipment requiring strong structural support and reliable traction during movement.
Used for heavy construction equipment operating on rough ground, including specialized machinery and tracked equipment.
Steel tracks provide durability and traction for equipment working in confined, uneven and abrasive underground environments.
Suitable for custom machinery requiring high load capacity, robust construction and dependable crawler performance.
Steel track systems are designed around the customer's machine dimensions, operating weight and working conditions.
