HYDRAULICS

HYDRAULICS
Hydraulics is a branch of science and engineering concerned with the use of liquids to perform mechanical tasks.

Application

• Metal cutting machine tools
• Presses, including cushions, clutches & brakes
• Automated assembly systems
• Pulp and paper industries
• Material handling and robotic systems
• Grinding and honing applications
• Car washes
• R & D test facilities
• Foundries and primary metals plants
• Component test stands

The word "hydraulics" comes from the Greek word ὑδϱαυλικός (hydraulikos) which in turn comes from ὕδϱαυλος meaning water organ which in turn comes from ὕδωϱ (water) and αὐλός (pipe).

EXCAVATOR



Excavators are heavy construction equipment consisting of a boom, stick, bucket and cab on a rotating platform. All movement and functions of a hydraulic excavator are accomplished through the use of hydraulic fluid, with hydraulic cylinders and hydraulic motors.

WORKING
THE ARM



The arm is comprised of two hydraulic cylinders, a bucket and a boom, which is on the upper part of the arm. The arm moves in two parts just like a human arm would: at the wrist and the elbow.

The Engine





Power in an automobile is normally received straight from the engine but it works differently in a hydraulic excavator. Because the machine uses a lot of force, it is able to move by changing the energy it receives from the engine into hydraulic power.

The Swing



One of the functions of this machine is its ability to turn. The swing of the excavator enables it to turn. The swing circle comprises of several components: an outer race, an inner race, ball bearings and a pinion.

The Cab



The third part of the hydraulic excavator is the upper structure where the driver’s seat is located and the controls are positioned. With the help of two levers on both side and two in the front, the driver can move both at the same time to control direction and height.
