Product Details
The Digger Undercarriage is developed to adapt to different equipment structures and working environments. Parameters such as track length, ground contact width, track plate thickness, track gauge, and travel drive system can be customized according to the host machine and application requirements.
For equipment upgrades and modification projects, the undercarriage system can be integrated with hydraulic control systems, electronic control systems, and remote operation technologies. This makes it suitable for improving the automation level and working efficiency of existing engineering equipment.
The modular design allows the undercarriage to be installed with fewer modifications to the original machine structure. This helps simplify the installation process and improves compatibility with different types of equipment.
Designed for demanding working conditions, the Digger Undercarriage provides stable operation on muddy sites, underground projects, soft soil areas, sandy environments, and uneven terrain. Its strong traction and load-bearing capability help equipment maintain reliable performance in complex working conditions.
The system is suitable for engineering machinery manufacturers, equipment integrators, and international suppliers looking for durable and customizable tracked chassis solutions.

Based on years of experience in heavy equipment support, Moerfei provides integrated undercarriage solutions for engineering machinery, drilling platforms, and special tracked equipment.
The production process uses CNC precision machining and a standardized quality control system. Each manufacturing stage is monitored to ensure consistent product accuracy and stable performance, allowing the company to support both small customized projects and large-volume international orders.
Customized Design Supporting Scheme
Each application has unique and specific requirements. We can provide customized track chassis assembly solutions based on your device size, operating conditions, load capacity, track width, and drive system. Simultaneously providing OEM and ODM services to help customers shorten development cycles and improve equipment performance.
Durable Steel Structure Configuration
The Digger Undercarriage is manufactured using high-strength alloy steel plates and advanced forming processes. The structure is designed to provide good resistance against wear, impact, and deformation during heavy-duty operation.
The frame structure is optimized to handle uneven loads and impact forces generated during equipment operation. This improves overall stability and helps reduce vibration under high-load working conditions.
The reinforced design also helps reduce stress concentration and component wear during continuous use. By improving structural durability, the undercarriage can lower maintenance requirements and extend the service life of the equipment.
