ONSITE MACHINING OF SLEW BEARING
  • Perform large site machining projects up to 14m dia.
  • Slew bearing installation and alignment also performed by our skilled technicians.
ROLLING THE SLEW GEAR RIM FORGED HOFALLOY PLATE
10.2 metre forge/fabricated slew gear manufactured from AGMA grade 2 plate during the initial rolling of the rim plate. The plate shown is 150mm thick, however plate is stocked up to 220mm thick.
GEAR CUTTING THE SLEW GEAR
The 4 segment 10.2m dia slew gear is being cut as an assembled ring. This ensures accurate pitching over all the split lines.
  • Individual segment lengths from 1m to 12m possible.
FINAL PREPARATION OF COMPLETED SLEW GEAR
Final preparation for despatch including corrosion protection prior to securing in fully enclosed crates.
  • Assembly simplified by having long segment lengths.
