efficiency and compact design
high pressure technology increases the efficiency of the hydraulic system
single or Dual speed motors with built-in counterbalance valve and relief valves
hydraulic brake directly applied upon the motor
automatic speed change obtainable upon request
wet disk brake patented technology
lower working temperature, higher system efficiency
working temperature range – 40°C / + 110°C
Reliability and Durability
low displacement, high pressure motors for longer existence of critical components and increased durability of the entire system
complete Bronze cylinder sleeves on rotating block
bimetallic (Bronze/Steel) distribution plate
rotary group with differential springtime system which increases electric motor life
gearbox main seal with triple seal program: mechanical labyrinth, v-band seal, main oil seal
main seal easily replaceable without gearbox disassembly
gearbox main Planetary Track Drive bearing manufactured from a single part, easily replaceable, completely 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, platform boom-lifts, soil compactors, pavers, etc. Because of the small and effective design that integrates electric motor and planetary gearbox on the PMCI versions, the use of expensive fully adjustable motors can often be avoided.
