20 ton crawler excavator
Core Performance & Work Efficiency：With an operating weight of 21.2 tons and a standard 1.06 m³ bucket, this model strikes an optimal balance between power and capacity. Its standout feature is the powerful 146 kN bucket digging force, enabling it to tackle hard soil and compacted materials with ease. The machine boasts a strong 70% gradeability and utilizes a long-track design (track length 4140mm, gauge 2380mm), resulting in a low ground pressure of just 49.8 KPa. This significantly enhances flotation and overall stability on poor ground, minimizing sinkage.
Power System & Fuel Economy：The SH210 is powered by the proven and reliable 6BTA5.9 turbocharged diesel engine, delivering a rated power of 133 kW at 2000 r/min. This provides ample power reserves and responsive performance. Coupled with a large 330-liter fuel tank, it supports extended continuous operation, reducing refueling downtime and significantly boosting machine availability and overall operational efficiency. This powertrain is renowned for its durability and low maintenance costs.
The SH210 Crawler Excavator is a high-performance 21-ton class engineering machine, purpose-built for demanding and complex working conditions. Integrating formidable digging power, exceptional stability, and excellent fuel efficiency, it is perfectly suited for a wide range of heavy-duty applications, including mining, earthmoving, infrastructure construction, and large-scale municipal projects. Its robust crawler undercarriage ensures superior traction and operational stability on soft, uneven terrain, making it the ideal choice for professionals prioritizing productivity and reliability.
Working Range & Operational Agility
The machine is designed with excellent working dimensions: a maximum digging height of 10.95 meters, a maximum digging depth of 6.49 meters, and a maximum digging radius of 9.86 meters, offering a wide and flexible operating envelope. Its fast swing speed of 12.4 r/min facilitates quick cycle times, enhancing efficiency in combined operations like truck loading and grading. The travel system features two-speed settings (5.1 km/h and 3.1 km/h), balancing site mobility with precise control.
Structural Design & Durability
The SH210 employs a reinforced engineering design, with key structural components optimized and strengthened for durability. The undercarriage is exceptionally robust, featuring 600 mm wide track shoes. Its compact tail swing radius of 2.925 meters and a counterweight ground clearance of 1075 mm enhance safety when operating in confined spaces, preventing collisions with obstacles. The machine layout is service-friendly, with easy access to routine maintenance points.
Operator Comfort & Serviceability
The cab is designed with operator comfort and excellent visibility in mind, configurable with an ergonomic suspension seat and a low-noise environment. The 250-liter hydraulic oil tank ensures efficient system cooling and fluid cleanliness. With a generous minimum ground clearance of 468 mm, the machine's over-ground capability is enhanced. External piping and components are thoughtfully arranged, making daily inspections, filter changes, and routine maintenance more convenient, effectively reducing service time and costs.
Hydraulic System & Precision Control
(Assumed based on industry standards) The SH210 is expected to feature an advanced load-sensing hydraulic system. This technology precisely allocates hydraulic flow and pressure according to real-time operational demands, enabling smooth, accurate control of all movements while minimizing energy loss. The high-flow main pump ensures powerful and coordinated compound actions, delivering exceptional operability and efficiency for both fine grading and aggressive digging tasks.
