Q:When was the excavator invented in that country?
In 1880, the first semi - rotary steam shovel with tractors as the chassis appeared.From the early twentieth Century to the late 40s, excavators entered the stage of diversification of power and walking equipment. In 1910, the first motor driving the excavator; appeared 1912 gasoline and kerosene engine driven rotary excavator produced in 1916; the diesel engine driven generator single bucket excavator; 1924 diesel engine direct drive for single bucket excavator; crawler walking device introduced in 1910. With the development of the automobile industry, the tire walking device is widely used in small excavator. In 30s, a walking device appeared.In the middle of 50s, Germany and France developed the full rotary hydraulic excavator successively, and the development of excavator entered a new stage.

Q:What is the function of the central swivel joint of the excavator?
The excavator chassis and the upper body do relative rotation movement, and the central joint is to ensure the supply of hydraulic circuit when turning. When the excavator turns, the hydraulic oil is sent to the walking motor through a central joint. It is difficult for an ordinary pipe to perform such a function as a central joint, and even if it is done, the pipeline life is not as good as that of the central joint
