Excessive Noise Levels

Old, worn conveyor rollers are a prime source of noise in any distribution center.

Precision-milled rollers on conveyors at Excel reduce noise to <65 db.
Problem
  • Sources of material handling noise:
    • Conveyors (steel bins on steel rollers, chains, low-quality bearings) are typically the noisiest component of a material handling system.
    • Excessive forklift truck traffic.
    • Rattling tow carts caused by uneven floor surface.
  • Increased worker fatigue, reduced productivity.
  • More difficult for workers to communicate, alert to safety hazards.
  • Higher employee turnover.
  • Noise forces supervisor offices to be located away from work areas.
Solution
  • Perform regular maintenance on conveyors (replace worn/misaligned bearings, worn guides, etc.).
  • Install coated conveyor rollers where possible.
  • Upgrade conveyors to low noise (<65 db) system.
  • Patch or replace uneven floors.
  • Re-route and/or reduce forklift traffic.
  • Replace fuel-powered forklifts with electric.
  • Install noise barriers around material handling equipment where possible.
