efficiency and compact design
high pressure technology increases the efficiency of the hydraulic system
single or Dual speed motors with included counterbalance valve and comfort valves
hydraulic brake directly applied on the motor
automatic speed change offered upon request
wet disk brake patented technology
lower functioning temperature, higher system efficiency
working temperature range – 40°C / + 110°C
Reliability and Durability
low displacement, ruthless motors for longer lifestyle of critical elements and increased toughness of the whole system
full 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 system: mechanical labyrinth, v-band seal, main oil seal
main seal easily replaceable without gearbox disassembly
gearbox main bearing made of an Planetary Track Drive individual part, easily replaceable, completely given pre-set load
Besides excavators, the PMCI drives with higher decrease ratios can be utilized on a number of applications: travel drives for mobile crawler cranes, crushers, system boom-lifts, soil compactors, pavers, etc. Thanks to the compact and effective style that integrates motor and planetary gearbox on the PMCI versions, the usage of expensive fully variable motors can frequently be avoided.
