2. Key Features & Advantages

2.1 Excellent Power & Fuel Economy

Matched with Komatsu exclusive HydrauMind load-sensitive hydraulic system, which realizes precise matching of power output and operation demand, reduces unnecessary energy loss. Its comprehensive fuel consumption is 10%~15% lower than similar products in the same class, with average fuel consumption of only 3~5 L per hour under economic mode.
The engine is optimized for low-speed high-torque output, adapts to harsh working conditions and low-quality fuel, with low failure rate.

2.2 High Flexibility & Controllability

Ultra-compact body design, suitable for operations in narrow spaces such as urban alleys, indoor demolition sites, and residential areas.
Ergonomic pilot control joystick with low operating force, greatly reduces operator fatigue during long-time work. 3 optional operation modes: Power mode (for heavy load digging), Economy mode (for daily operation to save fuel), Fine mode (for precision work such as ground leveling and pipeline laying).

2.3 Superior Durability

High-strength thickened steel plate is used for key structural parts including boom, arm and undercarriage, and all pins are equipped with dust-proof sealing structure, which extends the service life of wearing parts by more than 20%.
Optional reinforced rubber track (will not damage asphalt and pavement) or wear-resistant steel track, adapts to different construction grounds.
Multi-level filtration system for engine oil, fuel and hydraulic oil, effectively avoids contamination caused failures.

2.4 Operator Comfort & Safety

ROPS/FOPS certified enclosed cab, effectively guarantees operator safety in case of rollover or falling object impact.
Adjustable air suspension seat, fully sealed cab with sound insulation design, the operating noise inside the cab is only 72 dB(A). It is also equipped with high-efficiency air conditioning, USB charging port, large storage space and adjustable operation armrest.
270° wide field of view, optional rear view camera and additional working lights for night operation.

2.5 Easy Maintenance & Intelligent Management

All daily maintenance points (air filter, oil filter, fuel filter, hydraulic oil level check port) are designed to be accessible from the ground, no need to climb the machine, greatly reduces maintenance time.
Equipped with Komatsu exclusive KOMTRAX remote monitoring system, supports real-time checking of equipment location, working hours, fuel consumption, fault warning and other data, which is convenient for fleet management and reduces downtime.
