Equipped with a 6-cylinder turbocharged engine, the SH220-8 has a rated power of 133kW @ 2000rpm, which is 8% higher than that of similar products in the market. The advanced direct injection technology and turbocharging system ensure that the engine outputs stable and strong power even in high-load and harsh working conditions such as digging hard rock and carrying heavy materials. The large power reserve not only enables the excavator to complete heavy-duty operations with ease but also lays a solid foundation for fast efficiency improvement. Meanwhile, the engine adopts an optimized combustion system, which meets the EU Stage IIIA emission standard and achieves the dual effects of environmental protection and energy saving.
Benefiting from the large engine power and the matching advanced variable piston pump hydraulic system, the SH220-8 has a maximum bucket digging force of 146kN and a standard bucket capacity of 1.06m³. The hydraulic system realizes precise control of the working device, with a response time of only 0.3 seconds, which significantly shortens the cycle time of digging, lifting and unloading. In actual construction tests, the SH220-8 can complete 8-10 more digging cycles per hour than ordinary excavators, and the daily construction volume is increased by more than 15%. In addition, the intelligent control system can automatically adjust the engine power output according to the working load, avoiding energy waste and further improving operation efficiency.
As a professional crawler excavator, the SH220-8 has inherent advantages in terrain adaptability and stability. The crawler system adopts high-strength wear-resistant steel plates, with a ground contact area expanded by 10 times compared with wheeled equipment, reducing the ground pressure to 48kPa. This design allows the excavator to move freely in soft soil, swamps, sand and other complex terrains without sinking, which is impossible for wheeled equipment. The 3.2-meter-long contact track and anti-skid track spikes enhance the grip and traction of the equipment, enabling it to climb 45-degree slopes smoothly. At the same time, the crawler frame is made of Q690 high-strength steel, which can evenly disperse the impact force generated during operation, effectively extending the service life of the equipment and reducing maintenance costs.
With its comprehensive performance advantages, the SH220-8 Crawler Excavator is widely used in: 1. Mining and earthmoving operations; 2. Road construction and demolition projects; 3. Urban infrastructure construction and foundation excavation; 4. Water conservancy engineering and river channel dredging. Whether it is the harsh environment of a desert mine or the complex terrain of an urban construction site, the SH220-8 can maintain efficient and stable operation, helping customers complete projects on schedule with high quality.
