|Motorized drum is the ideal belt conveyer drive device. However, such as engineering locomotive belt conveyor, airport luggage carrier aircraft, load transfer belt conveyor, crawler loader etc. Where is power by Internal combustion engine to provide hydraulic power source, it is hard to use motorized drum because lack of eletric power, Then the hydraulic drum is the ideal choice for drive device in above situation. YDM hydraulic drum is a new type of drum pulley developed by our company based on motorized drum. It is a drive device which is combined the hydraulic motors, planetary reducer, driving pulley as a integral device. Hydraulic drum with a light weight, high specific power, good reliability, high efficiency, long life, wide speed range, low noise characteristics. Now has widely used for belt conveyer.
