A Brief History of excavators


More than 130 years have passed since the first manual excavator was introduced. During this period, it has experienced the gradual development from the steam-driven bucket rotary excavator to the electric and internal combustion engine driven rotary excavator, as well as the use of electromechanical hydraulic integration technology of automatic hydraulic excavator. Process.

Due to the application of hydraulic technology, the tractor in the 1940s appeared with hydraulic backhoe mounted excavator. In the early and middle 1950s, traction bearing hydraulic excavator and crawler hydraulic excavator were developed successively. The initial trial production of hydraulic excavator using the hydraulic technology of aircraft and machine tools, lack of hydraulic components suitable for various working conditions of excavator, manufacturing quality is not stable enough, the accessories are not complete. Since 1960's, the hydraulic excavator has entered the stage of promotion and vigorous development. Various countries excavator manufacturers and varieties increased rapidly, the output soared. From 1968 to 1970, the production of hydraulic excavators accounted for 83 percent of the total excavator production, and now it is close to 100 percent.

Advantage of Engine Cylinder Liner Kit

  • Greater resistance. Making liners separately from the engine block allows the use of special higher performance materials than those used for the construction of the block itself. Liners are generally made in special cast iron alloys containing elements with natural lubricating properties, like graphite. Other components are added like chrome, vanadium, and molybdenum to help ensure resistance to corrosion and wear caused by high temperatures.


  • Easier maintenance. When liners are worn they can be replaced more easily than changing an entire cylinder block.


  • Higher thermal conductivity. At operating temperatures the liners heat up more than the cylinders and must be able to expand in both diameter and length. If they were cast together with the cylinders, the resulting thermal loading would be high enough to fracture the materials.


  • Less risk of defects. The more complex a casting, the more difficult it is to achieve perfectly even surfaces with low residual stresses.
