efficiency and compact Planetary Track Drive design
high pressure technology escalates the efficiency of the hydraulic system
single or Dual quickness motors with included counterbalance valve and comfort valves
hydraulic brake directly applied upon the motor
automatic speed change available upon request
wet disk brake patented technology
lower operating temperature, higher system efficiency
working temperature range – 40°C / + 110°C
Reliability and Durability
low displacement, high pressure motors for longer life of critical elements and increased toughness of the entire system
complete Bronze cylinder sleeves upon rotating block
bimetallic (Bronze/Metal) distribution plate
rotary group with differential spring system which increases electric motor life
gearbox primary seal with triple seal program: mechanical labyrinth, v-band seal, main oil seal
main seal easily replaceable without gearbox disassembly
gearbox main bearing made of a single part, easily replaceable, fully supplied with pre-set load
Besides excavators, the PMCI drives with higher decrease ratios can be used on many applications: travel drives for cellular crawler cranes, crushers, system boom-lifts, soil compactors, pavers, etc. Thanks to the small and effective style that integrates engine and planetary gearbox on the PMCI versions, the usage of expensive fully variable motors can often be avoided.
