Product Description:

Product Description:

Excavators are heavy construction equipment consisting of a boom, stick, bucket and cab on a rotating platform known as the "house". The house sits atop an undercarriage with tracks or wheels. A cable-operated excavator uses winches and steel ropes to accomplish the movements. They are a natural progression from the steam shovels and often called power shovels. All movement and functions of a hydraulic excavator are accomplished through the use of hydraulic fluid, with hydraulic cylinders and hydraulic motors. Due to the linear actuation of hydraulic cylinders, their mode of operation is fundamentally different from cable-operated excavators.



Main Product Features:

  1. There are 3 pumps: the two main pumps are for supplying oil at high pressure (up to 5000 psi) for the arms, swing motor, track motors, and accessories, and the third is a lower pressure (700 psi) pump for Pilot Control.

  2. The whole machine has the elegant streamline design, reliable performance and high efficiency of working.

  3. Possess quality certification of ISO 9001:2000. Can pass CE test.

Should be adjusted displacement, huh, huh?.The regulator has a adjustable bolt, this is a power regulating pump, clockwise is power up, of course, is small counterclockwiseFormula: power = pressure multiplied by the flow in the engine speed will not be under pressure in the pump output flow more (note that the two pump together, at 90 degrees for an adjustment value, can not be adjusted too much, otherwise it will be my car phenomenon)In the middle of the two pumps, there is also a big number of adjusting bolts, this is to adjust the maximum tilt angle of the pump swashplate. Similarly, the greater the swashplate tilt angle, the greater the displacement of the pump. This is clockwise, the angle becomes smaller, and the counterclockwise becomes larger. I hope my answer will be helpful to you.
