en.Wedoany.com Reported - Taiyuan Heavy Industry (TZ) has successfully launched a 38-ton gravity energy recovery excavator. This new product achieves an estimated 15% energy savings through the recovery and utilization of the boom's gravitational potential energy, saving 5-6 liters of fuel per hour.
The core technology of this product lies in the company's pioneering "dual-circuit synergistic integrated control strategy for drive and potential energy storage and utilization." This technology isolates the boom lifting circuit, enabling it to independently recover, store, and reuse gravitational potential energy. Energy is recovered when the boom descends and released when it rises, without occupying other power systems of the machine. This circuit can share a single intelligent controller with other circuits, helping to reduce costs and save layout space, resulting in a more compact overall machine structure.
The energy recovery and utilization process of the boom involves only three steps: converting gravitational potential energy into hydraulic energy, which is then directly used for the boom's ascent, achieving direct energy utilization. According to design estimates, this technology can save 15% energy, equivalent to saving 5-6 liters of fuel per hour.
Taking a loading operation as an example, with 8 hours of work per day and a diesel price of 8 yuan per liter, this excavator can save over 300 yuan in fuel costs per day, approximately 10,000 yuan per month, and over 100,000 yuan per year. Users will refuel less frequently, extending effective operating time.
TZ stated that it will continue to develop more precise solutions based on actual user needs, addressing specific pain points, and making each piece of equipment a "green asset that earns money" in the hands of users.
