gearbox main bearing made of a single part, easily replaceable, fully given pre-set load
Besides excavators, the PMCI drives with higher reduction ratios can be utilized on many applications: travel drives for mobile crawler cranes, crushers, system boom-lifts, soil compactors, pavers, etc. Because of the small and effective design that integrates electric motor and planetary gearbox on the PMCI versions, the use of expensive fully variable motors can often be avoided.
