Amid the surge in infrastructure construction and resource development, the SK350 excavator's 16-meter two-stage telescopic boom, with its groundbreaking design, has become a "golden partner" for deep-dig operations. It not only redefines the excavator's operational boundaries, but also provides a new solution for complex projects with its efficient and precise performance.

The "Key" to Unlocking Difficult Deep Working Conditions:
- Municipal Pipeline Construction: For deep-buried underground pipelines (such as sewage and water pipes), the boom can precisely reach deep working points and complete the work in conjunction with a grab or crushing device.
- Landfill Remediation: In large landfills, the boom can reach the bottom of the pit to compact, sort, or remove landfill materials, preventing equipment from becoming stuck in the landfill layer.
Core configuration supports deep-dive operations:
- Load Capacity: The main body of the boom is made of Q690D steel. Even when fully extended, it can stably support the operating load of attachments such as grabs and buckets, ensuring maximum power output during deep-dive operations.
- Control Precision: Equipped with the hydraulic control system of the Kobelco SK350 excavator, the telescopic boom responds with millimeter-level precision, enabling precise control for both delicate deep water dredging and safe operations at the edge of deep foundation pits.
A Comprehensive Breakthrough from Efficiency to Effectiveness:
- Maximized Operating Range: The ultra-long 16-meter boom exponentially expands the operating radius and depth. A single unit can cover areas previously requiring multiple units, reducing equipment investment and site coordination costs.
- Minimized Construction Costs: The boom eliminates the need for frequent equipment movement or auxiliary work platforms, significantly reducing fuel consumption, work hours, and labor.
- Greater site adaptability: In confined working conditions (such as urban river channels and deep foundation pits near densely populated buildings), deep operations can be completed from a small footprint, eliminating the need for extensive space. This makes the SK350 excavator perfectly suited to complex urban construction environments.
The SK350 excavator's 16-meter, two-stage telescopic boom, with its "deep working capability" and efficient performance, has become a key tool for engineers tackling challenging deep working conditions. Whether in water conservancy, construction, or municipal engineering, it has proven its value: if the working conditions are deep enough, its value is real.
