Wittgen W2000 feeding motor 41685

According to the milling width of the road milling machine, road milling machines are divided into three categories: large, medium, and small. Except for small milling machines that may not require external feeding devices during operation, both large and medium-sized milling machines require external feeding devices to transport waste materials broken by the milling rotor to the material truck. At present, the driving form of most road milling and planing machine feeding devices on the market mainly uses an engine directly connected feeding pump. The feeding motor speed can be controlled by adjusting the engine speed and the displacement of the feeding pump (the feeding motor is usually a quantitative motor). During construction on the construction site, because the operator is more accustomed to adjusting the engine speed to the maximum position, there is often a situation where the feeding motor runs at high speed for a long time. However, in shallow milling, the motor speed does not need to reach such a high value to complete the feeding. In this case, not only does it waste the power of the entire machine, but it also shortens the service life of hydraulic components and exacerbates the wear of vulnerable parts such as belts.
