HIGH PERFORMANCE HYDRAULICS
The efficient conversion of engine power into hydraulic muscle lies behind the efficiency of New Holland mini-excavators. All models have three separate pumps to deliver optimized performance when traveling between sites or using the dozer blade, when working with the excavator and when driving hydraulic attachments. For demanding auxiliary attachments, a fourth pump option is available for the E57C and E60C.
To ensure smooth operation, valves control the flow of oil as the rams are fully extended and retracted, automatically providing a cushion effect to smooth the operation of all key functions. This reduces shock loads transferred to the machine and operator, reducing fatigue. This feature is further enhanced by the inclusion of an accumulator within the hydraulic circuit.
To further boost performance, the E57C and E60C have hydraulic flow summation. This advanced system delivers the enhanced proportional control typically restricted to high-capacity excavators exceeding 20-ton capacity.
