efficiency and compact design
high pressure technology escalates the efficiency of the hydraulic system
single or Dual acceleration motors with included counterbalance valve and comfort valves
hydraulic brake directly applied upon the motor
automatic speed change offered 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 lifestyle of critical elements and increased strength of the entire system
full Bronze cylinder sleeves upon rotating block
bimetallic (Bronze/Metal) distribution plate
rotary group with differential springtime system which increases engine life
gearbox main seal with triple seal system: mechanical labyrinth, v-band 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 decrease ratios can be used on several applications: travel drives for cellular crawler cranes, crushers, system boom-lifts, soil compactors, pavers, etc. Because of the small and effective design that integrates motor and planetary gearbox on the PMCI versions, the use of expensive fully variable motors can frequently be avoided.
