The SH220-8 excavator is equipped with a premium Linde hydraulic system—an upgrade that goes far beyond superficial enhancements to deliver a comprehensive boost to the machine’s core performance.

Thanks to its custom-engineered load-sensing system, the excavator achieves a notable reduction in hourly fuel consumption, while simultaneously elevating both operational efficiency and fuel economy to new heights. Tailored to diverse job site demands, it offers three selectable working modes that can be precisely optimized and matched to specific applications. This intelligent mode-switching capability not only cuts down energy waste but also maximizes work efficiency, ensuring the SH220 excels in scenarios ranging from light-duty excavation to heavy-load lifting with consistent, cost-effective performance.

SH220-8 Excavator Key Component Advantages

1. Excavator Movable Arm: Robust Design for Enduring Performance

The movable arm of the SH220-8 excavator adopts a large cross-sectional structural design, laying a solid foundation for withstanding heavy loads. Our engineers have implemented targeted reinforcement treatments on high-stress areas that bear the brunt of operational forces, significantly enhancing the arm’s wear resistance and load-bearing capacity. Meanwhile, through sophisticated structural optimization, potential stress concentration points have been effectively eliminated—this not only prevents fatigue damage caused by long-term force accumulation but also ensures the movable arm maintains excellent structural integrity even after prolonged exposure to harsh heavy-duty working conditions such as rock excavation and deep foundation digging.

2. Excavator Bucket Rod: Targeted Reinforcement for Reliable Force Transmission

As a core force-transmitting component in the digging system, the bucket rod is engineered with a precision reinforcement strategy. Based on in-depth analysis of force direction, magnitude, and stress distribution during actual digging and material-handling processes, we have concentrated reinforcement materials on the key stress-bearing sections. This targeted approach avoids the inefficiency of "all-around reinforcement" while drastically improving the rod's tensile and compressive strength. Even when confronting the intense impact and friction generated by breaking hard soil or lifting bulky materials, the bucket rod remains stable and durable, directly boosting the overall reliability and service life of the entire digging mechanism.

3. Excavator Bucket: Wear-Resistant Build for Cost-Efficient Operations

The bucket, the excavator's direct "working tool," is fabricated using high-grade wear-resistant alloy materials, selected specifically for their exceptional resistance to abrasion and impact. This premium material selection fundamentally solves the problem of rapid wear caused by long-term contact with gravel, ore, and other abrasive materials. Compared with standard buckets, its service life is extended by more than 30%, which not only reduces the frequency of maintenance and replacement, lowering downtime and spare parts costs, but also ensures continuous and efficient operation in high-intensity construction scenarios.

4. SH220-8 Excavator Lower X-Frame: Stable Foundation for Complex Conditions

The lower X-frame, as the "load-bearing backbone" of the excavator, is manufactured and processed entirely using advanced domestic and international precision equipment, ensuring consistent dimensional accuracy and structural stability of each component. For critical stress-bearing parts, we strictly implement non-destructive testing (NDT) procedures to thoroughly eliminate internal defects and guarantee absolute quality reliability. The track frame features a scientific structural design with 7 supporting wheels, paired with a standard configuration of 45 track plates—this combination optimizes the force distribution between the machine and the ground, significantly enhancing the overall stability and load-bearing capacity of the vehicle. Whether operating on uneven construction sites, muddy farmlands, or rocky mountainous areas, the lower X-frame enables the excavator to maintain smooth operation and strong passing performance, effectively adapting to diverse and complex working environments.
