planetary track drive

Features
efficiency and compact design
high pressure technology escalates the efficiency of the hydraulic system
single or Dual rate motors with built-in counterbalance valve and relief valves
hydraulic brake directly applied on the motor
automatic speed change obtainable 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, high pressure motors for longer lifestyle of critical parts and increased toughness of the whole system
complete Bronze cylinder sleeves upon rotating block
bimetallic (Bronze/Metal) distribution plate
rotary group with differential springtime system which increases electric motor life
gearbox main seal with triple seal system: mechanical labyrinth, v-ring seal, main oil seal
main seal easily replaceable without gearbox disassembly
gearbox main Planetary Track Drive bearing made of a single part, easily replaceable, completely given pre-set load

Besides excavators, the PMCI drives with higher decrease ratios can be utilized on many 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 models, the usage of expensive fully variable motors can often be avoided.
