Others are more dredging type operations where sand and gravel are recovered from rivers or lakes and processed. (SIC Code: 1442)

Critical Equipment Applications & Challenges Faced:

  • Bucket Pins & Bushings on Loaders -- Excessive wear due to extreme shock, high levels of water and abrasive dirt
  • King Pins on Trucks -- Excessive wear due to extreme shock, high loads and abrasive dirt
  • Bearings on Vibratory Shaker Screens -- Excessive wear due to constant shock environment and abrasive contamination
  • Gear Boxes on Conveyors, Crushers & Mills -- Overheated gear boxes due to extreme loading
  • Conveyor Bearings -- Short relubrication interval; lots of maintenance labor
  • Dredge & Transfer Pump Bearings -- Excessive heat, water wash out and resulting bearing loss
