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. Our products are according to the standard of OEM to manufacture.

Excavator Bulldozer undercarriage parts PC75 sprocket wheel front drive sprocket The four wheels refer to: rollers, drive wheels, idlers, and carrier pulleys. One belt refers to the tracks.
