The 30-Ton Long-Arm Digging Excavator is a specialized equipment designed for deep excavation tasks that require extended reach, such as river dredging and deep foundation pit construction. It features an extended working arm (customizable to 8-10m length) and a high-performance Cummins power system, ensuring both reach and digging force. With versatile functions including digging, trenching, dredging, and light lifting, it serves multiple construction scenarios that demand long-distance operation. The machine also incorporates a GPS-assisted positioning system, allowing operators to achieve precise excavation depths and slopes, reducing rework and improving project efficiency.
Extended Reach & Structural Strength: The custom long arm design—manufactured with high-strength alloy steel and heat-treated to enhance toughness—enables a maximum digging radius of 11000 mm and a maximum digging depth of 7000 mm. The arm’s connection points are equipped with large-diameter bearing pins and wear-resistant bushings, reducing friction and extending maintenance intervals to 800 operating hours. For ultra-deep tasks, an optional extended arm extension (1.5m) can be added, increasing the maximum depth to 8500 mm.
Power Configuration & Efficiency: A Cummins turbocharged diesel engine delivers 180 kW of power, perfectly matching the HIOS Ⅲ (Hydraulic Intelligent Operation System) hydraulic system. This combination minimizes energy loss by synchronizing engine speed and hydraulic flow with load demand, resulting in a 12% improvement in fuel efficiency compared to standard long-arm excavators. The hydraulic system also features a load-sensing valve, ensuring smooth operation even when multiple functions (e.g., arm extension + bucket rotation) are used simultaneously.
Attachment Compatibility & Versatility: The machine supports quick-change of a variety of attachments via a hydraulic quick coupler, which allows switching between tools in less than 5 minutes. Compatible attachments include: 1.4-1.6 m³ digging buckets (for soil and sand), hydraulic breakers (for rock breaking), grapples (for handling logs or construction waste), and dredging buckets (with perforations for water drainage during river cleaning). Each attachment is calibrated to work with the machine’s hydraulic system, ensuring optimal performance.
River and ditch dredging projects, such as cleaning sediment from urban rivers to improve water flow and prevent flooding
Pipeline and cable trench excavation, including long-distance oil/gas pipeline trenches (1.5-2m deep) and high-voltage cable trenches (3-4m deep)
Reservoir and foundation pit digging, such as deep foundation pits for large-scale industrial buildings (e.g., power plants and factories)
Port and harbor construction, including dredging berths to accommodate large cargo ships and excavating seabed foundations for dock structures
Q: What is the maximum unloading height, and can it load ore into large dump trucks commonly used in construction sites?
A: The maximum unloading height is up to 7200 mm, which is sufficient to load ore, soil, or other materials into large dump trucks with a cargo box height of 4-5m (e.g., 20-ton or 30-ton dump trucks). The machine’s bucket dumping angle (up to 110°) ensures complete material discharge, preventing residue buildup.
Q: Can it work in water, and what waterproof measures are included for amphibious operations?
A: Yes, it can operate in water depths of up to 1.5m with the optional waterproof package. The package includes: sealed electrical components (IP67 waterproof rating), corrosion-resistant coatings on the undercarriage and hydraulic hoses, and a high-mounted air intake (1.8m above the ground) to prevent water from entering the engine. For deeper water (2-2.5m), an optional extended air intake pipe is available.
Q: How heavy is the long arm attachment, and does it affect the machine’s stability during operation?
A: The standard long arm attachment weighs approximately 2800 kg, with a reinforced steel structure at the base to distribute weight evenly. The machine’s counterweight (8000 kg) is specifically designed to balance the long arm’s weight, ensuring stable operation even when the arm is fully extended. Additionally, the undercarriage’s track width (3200mm) enhances lateral stability, preventing tipping during side digging.
