bimetallic (Bronze/Steel) distribution plate
rotary group with differential spring system which increases engine life
gearbox primary seal with triple seal program: mechanical labyrinth, v-ring seal, main oil seal
main seal quickly replaceable without gearbox disassembly
gearbox main bearing manufactured from a single part, easily replaceable, fully supplied with pre-set load
Besides excavators, the PMCI drives with higher reduction ratios can be utilized on several applications: travel drives for mobile crawler cranes, crushers, platform boom-lifts, soil compactors, pavers, etc. Thanks to the small and effective style that integrates electric motor and planetary gearbox on the PMCI models, the use of expensive fully adjustable motors can often be avoided.
