Product Details
The Complete Tracked Undercarriage has ultra-high customization flexibility, and can adjust core parameters such as track length, grounding width, track plate thickness, overall track gauge, and walking drive structure according to equipment adaptation needs. The equipment is compatible with hydraulic basic control, intelligent electronic control system, remote control upgrade and transformation, and adapts to the supporting needs of various intelligent engineering equipment. Adopting a modular integrated structure design, assembly and docking can be quickly completed without changing the main structure of the host, with high adaptation efficiency and wide applicability. It can handle complex terrains such as muddy construction sites, underground tunnels, soft sand, and undulating farmland with ease. It has strong grip, stable load-bearing capacity, and excellent off-road performance. It is a high-quality supporting equipment for engineering machinery manufacturers, equipment integrators, and engineering trade enterprises.
Our Core Strengths
Our factory has a dedicated R&D team specializing in heavy-duty track chassis development. We design and match load capacity, hydraulic travel systems, and structural configurations according to the specific requirements of equipment such as excavators, drilling rigs, crushing machines, and screening equipment.
With years of experience in heavy equipment components, we provide complete crawler undercarriage solutions from design and manufacturing to technical support. The production process uses CNC precision machining and strict quality control procedures to ensure consistent dimensions and stable performance across batches. Our factory supports both standard and large-volume international orders with reliable production capacity and delivery schedules.

Customized Design Supporting Scheme
We provide tailor-made tracked chassis solutions based on each customer's specific requirements, including machine dimensions, working conditions, rated load capacity, track width, and travel drive configuration.
With flexible OEM and ODM services available, we work closely with customers to reduce development time, improve equipment stability, and strengthen the overall competitiveness of their products in the market. Our customized approach ensures the chassis is well matched to different application scenarios and equipment needs.

Durable Steel Structure Configuration
The Complete Tracked Undercarriage is formed by forging thick high-strength alloy steel plates, which have excellent wear resistance, impact resistance, and deformation resistance characteristics, and can withstand high-frequency, full load continuous heavy load operations for a long time. The rack structure is specially strengthened and optimized for heavy equipment under unbalanced load and dynamic impact conditions, resulting in lower vibration and smooth operation of the entire machine under full load operation. The integrated high-strength steel structure effectively reduces component wear and tear, reduces equipment downtime and maintenance frequency, lowers later operation and maintenance costs, and significantly extends the overall service life of the equipment.

Chassis Components
This track style emphasizes steady support for rotary drilling equipment. It is suitable for applications requiring precise positioning and safe movement.

Factory Production Line
The main components are manufactured through a combination of laser cutting and CNC bending processes, ensuring precise dimensions and consistent forming quality. Robotic welding systems are used to create strong and uniform weld joints, minimizing heat deformation and maintaining the overall structural strength of the chassis.
Key mounting surfaces and positioning holes are accurately processed by a gantry machining center to guarantee precise assembly and reliable fitting of each component. After production, all workpieces undergo shot blasting, automatic coating, and high-temperature curing treatment, providing excellent corrosion resistance and long-term protection against rust.
The final assembly process follows strict quality standards. All fasteners are applied with thread-locking adhesive and tightened according to specified torque requirements, reducing the risk of loosening during extended operation and ensuring stable, durable performance of the equipment.
