Excavator is one of the most important construction machinery in engineering construction. The materials excavated are mainly soil, coal, sediment and pre-loosened soil and rock,which is widely used in small mining, municipal construction, road construction, irrigation and water conservancy construction and other places. Excavator structure includes power plant, working device, rotary mechanism, control mechanism, transmission mechanism, walking mechanism and auxiliary facilities. The main working principle of the excavator is by the driving mechanism transfers the engine power to the hydraulic motor, the hydraulic cylinder and other executive components through the hydraulic pump, thus the operation of the working device is promoted and all kinds of operations are completed.

Ex400 Sprocket Undercarriage Parts Excavator Drive Sprocket The working principle of the excavator drive wheel involves power transfer. The power of an excavator is usually provided by an internal combustion engine or an electric motor. The internal combustion engine generates power by burning fuel and transmits the power to the drive wheels through the transmission. The electric motor converts electrical energy into mechanical energy and transmits it to the drive wheels through the transmission. Transmissions typically include components such as clutches, transmissions, and propeller shafts to control the speed and direction of power transmission.

Excavator Front Idler Assy Guide Wheel Roller DH220 Idler For Daewoo The function of an idler is to guide the track links into running smoothly and to prevent dislocation,idlers also carry some weight and therefore increasing groud pressure.there is also an arm in the center which supports the track link and guides the two sides.the smaller the distance between the idler and track roller,the better the orientation. Our products are according to the standard of OEM to manufacture.

Excavator Undercarriage Spare Parts Sk200 Track Roller, Bottom Roller The function of the roller is to transfer the weight of the locomotive group to the ground and roll it on the track. To prevent derailment, the roller should also be able to prevent the track from moving laterally relative to it. Rollers often work in mud and sand, and withstand strong impacts, the working conditions are extremely harsh, and the rim is easy to wear. The requirements for the roller are: the rim is wear-resistant, the bearing seal is reliable, and the rolling resistance is small. Our products are according to the standard of OEM to manufacture.
