An excavator arm consists primarily of a boom, stick, and attachments. Hydraulic cylinders power the movements of the parts, pins bind parts together, and linkage attaches parts to one another in ways that allow for parts to pivot to perform actions. While not part of the arm, the entire hydraulic system is controlled by the main hydraulic pump and main hydraulic valve, located in the house of the...

The excavator arm Hydraulic excavators work by allowing the operator to use levers to control the movement of the hydraulic system to push and move the cylinders that control the boom and bucket of an excavator. It is composed of three hydraulic pistons that operate in tandem with steel piston arms. The two main sections and bucket loader are connected by means of a hinge. The extension of the fir...

In general, it composes of a conventional backfill blade as well as provides an independent boom swing. A quite different from other various designs of heavy equipment in regards to the achievement of all sor...

A breaker is a powerful percussion hammer fitted to an excavator for demolishing concrete structures or rocks. It is powered by an auxiliary hydraulic system from the excavator, which is fitted with a foot-operated valve for this purpose. Demolition crews employ the rock breaker for jobs too large for jackhammering or areas where blasting is not possible due to safety or environmental issues. Rock...

A hydraulic excavator's operation body has the following three cylinders starting from the bottom; "boom cylinder", "arm cylinder", and "bucket cylinder". What is the function of arm cylinder in excavator? The cylinders function like the biceps and triceps of the machine, providing the power to move the arm in different directions. The control valves act like the machine's brain, directing the flo...

What is a backhoe breaker? A breaker is a powerful percussion hammer fitted to an excavator for demolishing hard (rock or concrete) structures. It is powered by an auxiliary hydraulic system from the excavator, which is fitted with a foot-operated valve for this purpose. What is the difference between a drop hammer and a hydraulic breaker? Compared to standard hydraulic breakers, the drop hammer a...

A hydraulic breaker chisel, also known as a hydraulic breaker bit or tool, is a critical component in a hydraulic breaker system. It is the part of the hydraulic breaker that comes into direct contact with the material being broken, such as concrete, rocks, or other hard materials. The hydraulic breaker chisel is responsible for transmitting the impact force generated by the hydraulic breaker to t...
