planetary track drive

Features
efficiency and compact design
high pressure technology increases the efficiency of the hydraulic system
single or Dual swiftness motors with integrated counterbalance valve and alleviation valves
hydraulic brake directly applied on the motor
automatic speed change obtainable upon request
wet disk brake patented technology
lower operating temperature, Planetary Track Drive higher system efficiency
working temperature range – 40°C / + 110°C
Reliability and Durability
low displacement, ruthless motors for longer life of critical components and increased toughness of the whole system
complete Bronze cylinder sleeves on rotating block
bimetallic (Bronze/Steel) distribution plate
rotary group with differential springtime system which increases motor life
gearbox primary seal with triple seal system: mechanical labyrinth, v-ring seal, main oil seal
main seal quickly replaceable without gearbox disassembly
gearbox main bearing made of a single part, easily replaceable, fully supplied with pre-set load

Besides excavators, the PMCI drives with higher decrease ratios can be utilized on a number of applications: travel drives for mobile crawler cranes, crushers, platform boom-lifts, soil compactors, pavers, etc. Because of the compact and effective style that integrates engine and planetary gearbox on the PMCI models, the use of expensive fully variable motors can often be avoided.
