Hydraulic Excavator
is it necesary to bleed the air from the hydraulic system in heavy equipments like the excavators? how?
my excavator hose has a leak. i installed new hose. the hydraulic oil was partially drained without my knowing. I started it but no response. I add oil but has no power. what would I do?
It entirely depends on where in the system the replaced hose was. If it was on the suction side of the pump, there may be trapped air that needs to be purged before the pump will start to pump again. If on the pressure side, it would not cause what you describe. Another thing is if the controls are pilot valve operated and the pilot system got air in it, it would need to be bled out. You may need to contact the service department at a dealership and ask for some help.

What is the excavator|digger?
Excavator, also known as mining machinery (excavating machinery), is higher or lower than the bucket digging machine bearing surface material, and into a transport vehicle or unloaded from the heap of earth-moving machinery yard. The material excavated soil, coal, sand, and through the pre-loose soil and rocks after. In recent years, from the perspective of the development of construction machinery, excavators, relatively fast development, while the excavator as a construction in one of the most important models of construction machinery, the correct selection also seems more important.
Advent of the first hand excavator has been 130 years of history, during which they experienced from the steam-driven rotary excavator bucket to the power-driven and internal combustion engine-driven rotary excavator, application technology, electromechanical integration, the gradual development of fully automatic hydraulic excavator process.
As the hydraulic technology, the 20th century, 40 years has been in the tractor equipped with a suspended hydraulic backhoe excavator, the 20th century, the early and mid 50s have developed a full-drag type rotary hydraulic excavators and crawler hydraulic excavators . The initial trial production of hydraulic excavators is the use of aircraft and machine tools, hydraulic technology, the lack of suitable working conditions of hydraulic excavators of various components, manufacturing quality is not stable enough, and the supporting parts are not complete. 60 years from the 20th century, the hydraulic excavator to enter the promotion and vigorous development stage, and excavators manufacturing plants and varieties to increase rapidly, output soared. 1968-1970 years, hydraulic excavator excavator production accounts for 83% of the total output is currently close to 100%.
