The YTH series external motor planetary gear electric motorized pulley is a premium heavy-duty drive solution engineered for the most demanding industrial conveying applications. Featuring a separately mounted external motor combined with an internal planetary hard-tooth gear reducer, it delivers unmatched load capacity and reliability. With dual cooling — motor air cooling plus drum internal oil cooling — the YTH series sustains continuous heavy-load operation without overheating. Designed for large-scale mining main conveyors, port bulk material handling, power plant coal systems, and long-distance inclined conveying, it is the definitive choice where maximum power and durability are required.
