Excavators
22-ton large crawler excavator powered by 118 kW Cummins QSB4.5 engine and electronic positive-flow hydraulics, delivering high bucket force and fast swing speed for mass excavation, mine stripping, and river dredging.
Engine Power
118 kW / 158 HP
Operating Weight
22,000 kg
Blade / Bucket Capacity
0.93 m³
Electronic Positive-Flow Hydraulics
Demand-driven variable-displacement pump reduces fuel burn by up to 8% versus fixed-pump competitors while maintaining smooth simultaneous control of all working functions.
FEA-Optimised Structural Steel
Finite-element-analysis designed boom, stick, and bucket-link castings resist fatigue cracking under high cyclic loads in continuous quarry and mass-excavation service.
Load-Sensing Proportional Swing
Proportional swing control decelerates automatically as the boom approaches the truck loading position, preventing material spillage and protecting truck body panels.
Five-Mode Working Control System
Selectable Power, Economy, Attachment, Lifting, and Breaker modes optimise engine speed, pump flow, and hydraulic pressure for each specific application and tool type.
