21 Ton Excavator with Thumb

 

JH8210 21 ton

Crawler excavator

Operating weight: 21000kg

Bucket capacity: 1m³

 

The precision matching design integrated with energy-saving control optimizes system coordination, reducing fuel consumption by minimizing power loss during operation. This intelligent pairing adjusts hydraulic pressure and engine output based on load demands, ensuring efficient energy use.

Turbocharging technology boosts air intake, enhancing adaptability in plateau regions. It maintains consistent power output at high altitudes where oxygen is thin, ideal for construction projects in mountainous areas.

The funnel-shaped fan cover adopts an aerodynamic design to increase air intake by 20%, improving heat dissipation efficiency. This ensures the engine and hydraulic system operate at optimal temperatures, preventing overheating during prolonged use.

An advanced hydraulic system with high-precision valves and variable pumps enhances digging force and operational smoothness, enabling faster cycle times and more precise movements.

The improved track frame cross-section features a curved design to reduce soil accumulation, minimizing sprocket wear by 30% and extending component lifespan. Its reinforced structure withstands heavy loads in rough terrain.

Enlarged front, side, and rear windows provide a 360°panoramic view, eliminating blind spots and improving safety. This design allows operators to monitor surroundings accurately, boosting efficiency in complex work environments.

During road construction, it can be used to dig road trenches, handle soft soil foundations, and clean side ditches to ensure the smooth progress of road construction.

During mining, the 21-ton crawler excavator can undertake ore loading and small mine development tasks. The crawler design allows it to walk on complex terrain as if it were flat ground, adapting to the harsh working environment of the mine.
