gearbox main seal with triple seal program: mechanical labyrinth, v-ring seal, main oil seal
main seal easily replaceable without gearbox disassembly
gearbox main bearing made of a single part, easily replaceable, completely given pre-set load
Besides excavators, the PMCI drives with higher decrease ratios can be used on a number of applications: travel drives for cellular crawler cranes, crushers, system boom-lifts, soil compactors, pavers, etc. Thanks to the compact and effective design that integrates electric motor and planetary gearbox on the PMCI models, the use of expensive fully variable motors can often be avoided.
