New 33t/35t/37.5t Heavy-Duty Large Crawler Excavator Large Excavator
1.Superior Digging Force & Heavy-Duty Performance:
With up to 256 kN bucket digging force (ISO) and operating weights from 33–37.5 tons, these large excavators deliver powerful, efficient performance in mining, quarrying, and large-scale earthmoving.
2.Extended Reach and Deep Digging Capability:
Achieve max digging reach of 11,100 mm and digging depth up to 7,270 mm—ideal for deep excavation, trenching, and infrastructure projects requiring high reach and depth.
3.High Mobility and Stability on Challenging Terrain:
Equipped with long track ground length (4,030 mm) and low ground pressure (as low as 65 kPa), these crawler excavators ensure excellent traction, slope performance (70% gradeability), and minimal ground disturbance.
4.Fuel Efficiency and Extended Operation Time:
Powered by Cummins or Isuz6MKLX engines and large 595L fuel tanks, these machines reduce refuel stops and lower operating costs, supporting long-hour operations in remote or demanding conditions.
5.Operator-Focused Design with Enhanced Comfort and Visibility:
The spacious cab, combined with high dig heights (up to 10,000 mm), excellent swing visibility, and minimal tail swing radius (3,420 mm), ensures safety, comfort, and productivity in confined or complex job sites.
Product description of Large Excavator:
1.Large Bucket Capacity & Operating Weight - Handles 1.4-1.9m³ bucket volumes and 33-37.5 ton operating weights, ideal for heavy-load earthmoving, mining, and major construction projects.
2.High-Efficiency Hydraulic Digging Force - Delivers up to 256 kN bucket digging force (ISO) for superior performance in tough digging, trenching, and loading applications.
3.Extended Digging Reach and Depth - Offers max 11,100 mm digging reach and 7,270 mm depth, enabling efficient large-scale excavation and deep trench work.
4.Enhanced Stability with Low Ground Pressure - Crawler design with long track length (4,030 mm) and ground pressure as low as 65 kPa ensures excellent stability on soft or uneven terrain.
5.High-Capacity Fuel System & Strong Gradeability - Features a 595L fuel tank and 70% gradeability for long-hour, remote operation with minimal refueling and high mobility on challenging slopes.
The Application of Large Excavator：
1.Mining & Quarrying
Material Extraction – Efficiently handles overburden removal and mineral extraction with bucket capacities up to 1.9m³ and digging depths to 7,270 mm.
Loading and Hauling – High breakout force (up to 256 kN) supports continuous loading of large trucks in open-pit mining and aggregate operations.
2.Heavy Construction & Earthworks
Deep Foundation Excavation – Reaches up to 11,100 mm for digging foundations, basements, and diaphragm walls in large-scale building projects.
Mass Earth Moving – Ideal for site development, pond digging, and land grading with long track grounding (4,030 mm) for enhanced stability.
3.Infrastructure & Road Construction
Trenching for Pipelines and Utilities – Capable of max vertical digging depth of 6,380 mm, suitable for deep utility trenches and drainage systems.
Embankment and Slope Work – Excellent gradeability (70%) enables safe and efficient work on steep slopes and uneven terrain.
4.Demolition & Industrial Applications
Structure Tearing-Down – High lift capacity and reach (max dump height: 7,135 mm) allow for effective demolition of medium-rise structures.
Material Handling and Stockpiling – Compatible with grapples and sorting buckets, ideal for scrap handling and raw material movement in ports and yards.
5.Remote and Large-Scale Projects
Fuel-Efficient Long-Duration Operation – Large 595L fuel tank and reliable Cummins/Isuzu engines support extended shifts in mining, forestry, or rural infrastructure with minimal downtime.
Rough Terrain Mobility – Low ground pressure (from 65 kPa) and robust undercarriage provide access and performance in challenging ground conditions.
