Reliability and Durability
low displacement, high pressure motors for longer lifestyle of critical parts and increased toughness of the whole system
complete Bronze cylinder sleeves on rotating block
bimetallic (Bronze/Metal) distribution plate
rotary group with differential spring system which increases motor life
gearbox primary seal with triple seal program: mechanical labyrinth, v-ring seal, main oil seal
main seal very easily replaceable without gearbox disassembly
gearbox main bearing manufactured from an individual part, easily replaceable, fully supplied with pre-set load
Besides excavators, the PMCI drives with higher decrease ratios can be utilized on many applications: travel drives for mobile crawler cranes, crushers, system boom-lifts, soil compactors, pavers, etc. Thanks to the compact and effective style that integrates electric motor and planetary gearbox on the PMCI models, the utilization of expensive fully adjustable motors can frequently be avoided.
