Features
efficiency and compact design
high pressure technology increases the efficiency of the hydraulic system
single or Dual velocity motors with integrated counterbalance valve and alleviation valves
hydraulic brake directly applied upon the motor
automatic speed change offered upon request
wet disk brake patented technology
lower operating temperature, Planetary Track Drive higher system efficiency
working temperature range – 40°C / + 110°C
Reliability and Durability
low displacement, high pressure motors for longer life of critical parts and increased durability of the entire system
full Bronze cylinder sleeves on rotating block
bimetallic (Bronze/Metal) distribution plate
rotary group with differential spring system which increases electric motor life
gearbox primary seal with triple seal system: mechanical labyrinth, v-ring seal, main oil seal
main seal very easily replaceable without gearbox disassembly
gearbox main bearing made of an individual part, easily replaceable, fully given pre-set load
Besides excavators, the PMCI drives with higher reduction ratios can be used on a number of applications: travel drives for mobile crawler cranes, crushers, system boom-lifts, soil compactors, pavers, etc. Thanks to the small and effective style that integrates motor and planetary gearbox on the PMCI models, the utilization of expensive fully variable motors can frequently be avoided.
