Inheriting Shandong Shitian's core energy-saving technology, the 6-ton excavator can be optionally equipped with a hybrid power system. Through potential energy recovery and storage technology, the energy generated during the descent of the working device is recovered and reused, reducing the comprehensive fuel consumption by 20%-25% compared with traditional equipment of the same tonnage. Calculated based on 2000 working hours per year and a fuel unit price of 8 yuan/L, it can save more than 15,000 yuan in fuel costs annually. It is equipped with a standard engine automatic idle function, which automatically reduces the speed when there is no operation, further reducing fuel consumption and noise pollution, complying with National III emission standards, and being more environmentally friendly and worry-free.

Key components are all selected from internationally renowned brands, including original imported hydraulic pumps, main valves and customized Cummins engines. The reliability of the core system has been verified by the market for more than ten years, and the failure rate is 40% lower than the industry average. The boom and arm adopt a box-type large-section structure and reinforced design with thick steel plate welding. Through stress analysis and durability fatigue testing, the service life is increased by 50% compared with ordinary structures, greatly reducing equipment maintenance and replacement costs.

On the premise of ensuring quality, the equipment purchase price is positioned affordably, 15%-20% lower than that of the same tonnage products of international first-tier brands. At the same time, maintenance parts are centrally distributed, 95% of which can be inspected and maintained standing on the ground. Vulnerable parts such as air filters and fuel filters are easy to replace without professional hoisting equipment. The time for a single routine maintenance is shortened to within 1 hour, the maintenance labor cost is reduced by 50%, and the whole-life cycle use cost advantage is significant.
