Product advantages
Comfortable Working Environment
The high-grade cab features an ergonomic seat with armrests, a dependable climate control system (air conditioning and ventilation), and an efficient heater. These integrated components create a comfortable and safe working environment for the operator.
Complete Hydraulic Pilot
The hydraulic pilot control system delivers exceptional precision by accurately regulating pressure, flow rate, and direction. This direct and responsive command enables high-accuracy control over all machine functions.
Spacious Flat Foot Space
The elegant interior design includes a roomy flat foot area, which enhances comfort by providing the operator with additional legroom.
Track
The standard configuration features a steel track, renowned for its wear resistance. As an optional alternative, the rubber track offers reduced noise levels, enhanced wear resistance, and greater adaptability to diverse working conditions.
Openable Windshield
This windshield not only allows for air circulation but also expands the operator's field of vision. Besides, it can be used as an emergency escape exit.
Easy Maintenance
The upper hood can be fully opened, which simplifies daily inspection and maintenance work.
Load-Sensing System
The combination of the full hydraulic system and the load-sensing system makes the excavator's operation more responsive.
Tailless Structure
This design provides enhanced articulation, enabling the excavator to operate effectively in confined spaces and on complex terrain. Its ability to turn and work within narrow areas is a key feature, resulting in renowned maneuverability and operational flexibility.
