Power and Hydraulic System: The engine adopting ACERT technology optimizes performance and complies with emission regulations, and reduces emissions through advanced technologies. The hydraulic system increases the hydraulic pressure by 2% to improve lifting force and digging force, and the regeneration circuit of the boom and stick can save energy.
– Operational Comfort: The cab is pressurized to 50Pa to reduce dust entry, equipped with a standard air conditioner, and the seat is adjustable. The labor-saving joystick control device is ergonomically designed to reduce operator fatigue.
– Ease of Maintenance: Many maintenance points can be accessed while standing on the ground. The LCD monitor can record the working hours of filters, oil, etc., and display the recommended replacement cycles. Sampling ports and test ports are provided for hydraulic oil, engine oil and coolant, facilitating diagnosis.
