20 Ton 21.5 Ton Wheel Excavator

The hydraulic pilot servo operation system ensures intuitive, precision-controlled maneuvers, allowing operators to handle complex tasks-from fine-grained bucket tilts to rapid boom swings-with minimal effort. This technology enhances operational efficiency while reducing fatigue, making it ideal for prolonged heavy-duty use in demanding environments.

Featuring a newly designed large closed cab, the excavator prioritizes operator comfort with air conditioning, an ergonomic suspension seat, and intuitive control layouts. The sealed cabin blocks dust and noise, while panoramic windows provide 360° visibility, ensuring safety and ease of operation in congested work zones.

Key load-bearing components like the chassis, boom, and bucket arm undergo strengthened design upgrades to meet high-intensity heavy-loading demands. Constructed from quenched high-strength steel and reinforced with stress-relieving rib structures, these parts withstand repeated impacts and heavy loads, maintaining integrity in mining and large-scale infrastructure projects.

A low-high speed traveling motor adapts seamlessly to varying road conditions. It delivers high torque for climbing steep terrain or traversing rough trails, while switching to high-speed mode for efficient road transfers, eliminating the need for auxiliary transport and saving relocation time.

Equipped with heavy-duty working equipment, a high-strength chassis, and an upgraded power hydraulic system, the excavator optimizes performance. The hydraulic system's enhanced flow and pressure ensure rapid cycle times for digging, lifting, and rotating, while the rugged chassis provides stable support on uneven ground.

Its multifunctional design suits diverse work conditions, excelling in mining, construction sites, bridge building, highway and high-speed railway projects, and river engineering. Whether excavating hard rock in mines, handling concrete demolition on bridges, or managing large-scale earthworks for railways, the excavator combines durability and efficiency to tackle complex, high-intensity tasks with reliability.
