Model: [SH220LC-8  Hydraulic Excavator]

Tonnage: [22.3 Ton]

Core Configuration: Cummins 6BTAA5.9 Engine | Reinforced Steel Structure | 360° Full Swing System

1. Cummins-Powered: Unmatched Heavy-Load Performance

Equipped with the Cummins  6BTAA5.9 engine, a globally recognized power core for heavy machinery, this excavator delivers a maximum output of 133kw and a torque of 708 N·m. The engine’s advanced fuel injection system cuts fuel consumption by 12% compared to similar tonnage models, while maintaining a stable power supply even under continuous 12-hour heavy-load operations.With a  a breakout force of 146 kN, it effortlessly handles rock crushing, ore loading, and large-scale earthmoving tasks—ideal for mining and infrastructure projects that demand high efficiency and low operating costs. The engine’s failure rate is controlled below 0.5% within 10,000 working hours, ensuring long-term reliable operation.

2. Crawler Chassis Design: Superior Adaptability to Complex Terrain

The reinforced crawler chassis features a track width of 3400 mm .Enabling the excavator to navigate muddy, rocky, and uneven construction sites without getting stuck. which improves the machine’s stability by 25% during high-lift and long-distance material handling.

3. Rigid Structure: Built to Withstand Extreme Working Conditions

The entire body frame is welded with high-strength steel, a material widely used in aerospace and heavy engineering fields, which boosts the structure’s impact resistance by 30% compared to standard Q355 steel. The boom and dipper stick are reinforced with double-layer steel plates, and key stress points are equipped with wear-resistant alloy bushings that extend the service life of structural parts by 50%.

After 15,000 hours of fatigue testing, the main structure shows no deformation or cracks, proving its durability for long-term heavy-duty work. This robust design reduces maintenance frequency by 40% and cuts annual maintenance costs by over $5,000 for users.

4. Flexible Maneuver: Precision Operation Even in Confined Spaces

Breaking the stereotype of "bulky heavy excavators", this model achieves a minimum turning radius of 2.9 meters and supports 360° continuous full swing. The advanced hydraulic control system enables precise micro-movement operations—operators can accurately adjust the bucket position within ±5 cm, meeting the requirements of narrow-space operations such as urban pipeline laying and building foundation excavation.
