Unveiling the High-Efficiency and Energy-Saving Fixed/Variable Hydraulic System for Electric Wheel Loaders!

Within the vast realm of construction machinery, loaders serve as indispensable workhorses. Its critical operations – bucket tilting, boom lifting and vehicle steering – all rely on high-performance hydraulic systems.
At the heart of this system lies the hydraulic pump, which delivers hydraulic oil through a pump motor to control valves. These valves then distribute the oil to hydraulic cylinders, driving their movements to execute various tasks. This process forms the foundation of the loader’s high-performance operation.
Fixed Hydraulic Pumps for Fixed Output
Currently, most loaders on the market utilize fixed hydraulic pumps, which deliver a constant flow of hydraulic oil regardless of actual operational demands.
While simple in design, this approach leads to energy waste and oil temperature spikes when demand falls below the pump’s output capacity. Excess oil circulates back to the tank, reducing efficiency and longevity.
Fixed/Variable Hydraulic System for Intelligent Response
In contrast, JGM860E employs a groundbreaking fixed/variable hydraulic system. Merging the stability of fixed hydraulic pump with the adaptability of variable hydraulic pump, it achieves precise oil flow control while minimizing heat generation in the pump motor.
During operations such as material handling or agile steering, the system intelligently adjusts oil output in real time to match workload requirements. This ensures optimal efficiency while minimizing energy loss during both heavy-duty tasks and low-demand scenarios.
Sustainable Operation with Reduced Energy Loss
The implementation of the fixed/variable hydraulic system significantly lowers energy consumption, achieving true eco-friendly and energy-efficient performance.
In complex working conditions, JGM860E demonstrates rapid response to operator commands, superior combined movement efficiency and exceptional traction/excavation forces. These features deliver higher productivity and lower operational costs to end-users.
