VE9 Self Lock Planetary Slew Drive Gearbox For Single Axis Solar Tracking System
Self Lock Planetary Slew Drive Description
VE, vertical series planetary gear slew drive gearbox's applications mainly for winch crane, slewingdeck crane, crane winch design, excavator swing drive, slewing
drive for solar tracking system etc. Our unique planetary gear reduction gearbox working principle makes
itself for solar
tracker bear a big radial load due to the proportionate
distribution of torque. What's more, our slewing drives has
hydraulic motor configurations. We have all series slew gearbox size meet customer different demand.
