planetary track drive

Features
efficiency and compact design
high pressure technology increases the efficiency of the hydraulic system
single or Dual acceleration motors with integrated counterbalance valve and relief valves
hydraulic brake directly applied upon 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 parts and increased strength of the entire system
complete Bronze cylinder sleeves on rotating block
bimetallic (Bronze/Metal) distribution plate
rotary group with differential spring system which increases electric motor life
gearbox main seal with triple seal program: mechanical labyrinth, v-band seal, main oil seal
main seal quickly replaceable without gearbox disassembly
gearbox main bearing manufactured from an individual 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 mobile crawler cranes, crushers, system boom-lifts, soil compactors, pavers, etc. Thanks to the small and effective design that integrates electric motor and planetary gearbox on the PMCI versions, the use of expensive fully adjustable motors can frequently be avoided.
