22T Hydraulic Crawler Excavator

Heavy-Duty Excavator – High Efficiency and Robust Performance for Mega Projects

Designed for large-scale construction, mining, and earthmoving, this heavy-duty hydraulic excavator delivers unmatched power, precision, and durability. With an operating weight of 23 t, it combines a sturdy undercarriage, advanced hydraulics, and an optimized work range, making it ideal for demanding projects such as quarrying, infrastructure development, and major civil engineering works. Its wide track gauge and reinforced tracks provide stability on uneven ground while minimizing soil disturbance.

At the heart of this machine is a WEICHAI WP6G175A0-II 6-cylinder diesel engine, producing 129 kW at 2,200 rpm. Engineered for continuous operation, it provides reliable torque, excellent fuel efficiency, and compliance with China Stage II emissions standards, enabling environmentally responsible operation without compromising performance. Coupled with a high-capacity 360 L fuel tank and 220 L hydraulic reservoir, this excavator can sustain long work cycles, reducing downtime and increasing on-site productivity.

The excavator’s boom and arm combination offers an impressive reach and digging envelope. The 5,700 mm boom and 2,925 mm arm allow deep excavation and high material placement, while the 1.1 m³ rock bucket can handle dense soils, gravel, and rock with a maximum bucket force of 150 kN and arm force of 110 kN. Operators can achieve digging depths up to 6.48 m, vertical wall cutting to 5.93 m, and dumping heights of 6.73 m, ensuring efficient trenching, foundation work, and material handling. The maximum digging radius of 9.85 m expands operational coverage and reduces the need for frequent repositioning.

The hydraulic system, operating at 34.3 MPa, ensures precise control and smooth movement of all attachments. Combined with a swing speed of 12 rpm, the excavator allows quick rotation for multi-angle digging and reduces cycle times significantly. Its climbing capability of 30° ensures safe operation on slopes and uneven terrain, while a dual-speed travel function supports site mobility with 5.6 km/h on high gear and 3.3 km/h on low gear.

Operator comfort and visibility are a top priority. The spacious cab, 3,060 mm in height, provides excellent line-of-sight for complex tasks. Ergonomically positioned controls and intuitive joystick operation reduce operator fatigue and improve accuracy in continuous operation. The machine also features a minimum slewing radius of 3.56 m for tight maneuvering around obstacles.

This excavator excels in high-output, heavy-duty applications, including quarrying, mining, dam construction, and large infrastructure projects. Its high digging capacity, robust structure, and advanced hydraulics deliver faster cycle times and improved project efficiency. The combination of a powerful engine, large bucket capacity, and extended reach makes it an indispensable tool for contractors seeking productivity, reliability, and operational precision.

With durable components, optimized hydraulics, and intelligent design, this heavy-duty hydraulic excavator provides a perfect balance between strength, efficiency, and operator comfort. It is a machine that meets the most demanding project requirements while maintaining a long service life, low operating costs, and consistent performance under the toughest conditions.
