What is Hydraulic Excavator
Definition of Hydraulic Excavator in Construction
A hydraulic excavator is a piece of mechanical excavating equipment specially designed to operate by the action of hydraulic cylinders and pistons. Hydraulics is the forcing of a hydraulic fluid, similar to light oil, into a cylinder that has a piston housed within this cylinder. When the fluid is pumped into the bottom of the cylinder, by a hydraulic pump, the piston is pushed up, and whatever piece of equipment that is attached to the end of the piston is moved. When the pressure is released, the piston will move back down into the cylinder, and the piece of equipment attached to the end of the piston will move in the opposite direction. Tremendous pressure can be obtained by the pumping of hydraulic fluid into the cylinder; therefore hydraulic excavators that operate on this principal can be extremely powerful. The creation of the hydraulic excavator changed the ability of construction equipment to operate, by improving the efficiency and the strength of the equipment over the belts, pulleys, chains and other types of pure mechanical systems that were used in the past.
