planetary track drive

Features
efficiency and compact design
high pressure technology increases the efficiency of the hydraulic system
single or Dual acceleration motors with included counterbalance valve and relief valves
hydraulic brake directly applied on the motor
automatic speed change available upon request
wet disk brake patented technology
lower operating 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 Planetary Track Drive sturdiness of the entire system
full Bronze cylinder sleeves upon rotating block
bimetallic (Bronze/Metal) distribution plate
rotary group with differential springtime system which increases 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 bearing manufactured from an individual part, easily replaceable, fully supplied with pre-set load

Besides excavators, the PMCI drives with higher reduction ratios can be used on several applications: travel drives for cellular crawler cranes, crushers, system boom-lifts, soil compactors, pavers, etc. Because of the compact and effective design that integrates motor and planetary gearbox on the PMCI models, the use of expensive fully adjustable motors can frequently be avoided.
