China manufacturer 20 tons drilling rig hydraulic crawler undercarriage for construction machinery

Our 20-ton class steel track undercarriage is specifically designed to meet the rigorous demands of the South American mining and construction sectors. Whether navigating the steep, rocky inclines of the Andes Mountains or operating in the humid, abrasive environments of Amazonian infrastructure projects, our chassis provides the stability and durability your equipment requires.

Why Choose Our 20-Ton Series for Your Project?

• Superior Gradeability & Traction: Equipped with high-torque integrated planetary final drives, our undercarriage delivers a massive 185 kN tractive effort, ensuring your machinery climbs 30° slopes with ease—essential for high-altitude terrace mining in Peru and Chile.

• SALT (Sealed and Lubricated Track) Technology: To combat the fine dust of the Atacama and the moisture of tropical regions, we use premium sealing technology that prevents internal pin and bush wear, extending the track's service life by over 30% compared to standard dry tracks.

• High-Clearance, Heavy-Duty Build: With a 460 mm ground clearance, our design protects critical hydraulic components from rock strikes and debris, reducing downtime in unpaved, rugged terrains.

• Universal Parts Compatibility: We understand the importance of maintenance in remote areas. Our 20-ton class components (rollers, links, and idlers) are engineered to be interchangeable with leading global brands, ensuring you can find spare parts in any local South American market.
Customizable for Your Needs: From specialized paint coatings for coastal corrosion resistance to wide track shoes for soft ground, we provide the localized engineering support you need to keep your fleet moving.
