Product Details
The Crusher Crawler Track Frame Assembly is a key structural component of mobile crushing equipment, providing essential support, load-bearing capability, and mobility during operation. Designed for heavy-duty working conditions, the crawler track frame features a robust structure, reliable impact resistance, and stable traveling performance, enabling mobile crushers to operate efficiently across various terrains.
The assembly can be customized according to different equipment models and operating requirements, including:
● Track length
● Ground contact width
● Track plate thickness
● Track gauge
● Travel drive configuration
This flexible customization allows the crawler track frame to match various types of mobile crushing and screening equipment used in mining, construction waste processing, quarrying, and outdoor engineering applications.
Designed to meet the requirements of modern equipment upgrades, the crawler track frame assembly supports integration with hydraulic travel systems, intelligent electronic control systems, and remote operation solutions. It provides equipment manufacturers with a reliable foundation for improving machine adaptability and upgrading existing mobile crushing equipment.
The modular integrated structure enables convenient installation and replacement without major modifications to the original equipment frame. This design improves compatibility, simplifies assembly procedures, and reduces downtime during equipment replacement or upgrading.
The crawler system is engineered for challenging working environments, including mining areas, mountainous regions, muddy construction sites, and soft ground conditions. Through optimized structural design and balanced load distribution, the track frame provides stable traction and reliable mobility, helping mobile crushing equipment maintain continuous operation under demanding conditions.
Product Advantages
The combination of powerful travel motors, reinforced tracks, and optimized drive components provides excellent traction. Machines can move confidently while carrying heavy loads.

Customized Design Solutions
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 crawler track frame assembly is manufactured using thick high-strength alloy steel plates, providing strong resistance against impact, wear, and structural deformation.
During crushing operations, mobile equipment is often exposed to continuous vibration, impact loads, and uneven stress distribution. To address these operating conditions, the track frame structure is optimized through mechanical design improvements, helping reduce vibration transmission, improve operational stability, and maintain reliable performance during long-term use.
The reinforced overall structure helps reduce component fatigue and wear, lowering maintenance requirements and extending the service life of mobile crushing equipment.

Technical Specifications (Crusher Crawler Track Frame Assembly Matching Scheme)
Technical specifications can be customized according to:
- Mobile crusher model
- Equipment weight
- Operating environment
- Required load capacity
- Track configuration
- Hydraulic drive system
Detailed technical drawings and matching solutions can be provided based on customer requirements.

Chassis Components
This design reduces pressure on the surface by increasing contact area. It is a practical choice for projects on fragile or loose ground.

Production Line Process
Crawler track frame components are processed through:
- Laser cutting
- CNC bending
- Precision machining
- Automated robot welding
To ensure accurate dimensions and consistent component quality.
Robot welding technology provides uniform and reliable weld seams, reducing the risk of welding deformation and improving the overall structural strength of the track frame.
Key mounting positions are machined using gantry machining centers to maintain precise assembly accuracy and ensure proper installation with the equipment body.
After fabrication, components undergo:
- Shot blasting surface treatment
- Automatic painting
- High-temperature drying
To improve corrosion resistance, rust prevention, and outdoor durability.
Finished products are assembled according to standardized procedures. Critical bolts are treated with thread-locking adhesive and tightened according to specified torque requirements, reducing the risk of loosening during long-term operation and ensuring stable equipment performance.
