High Tiering

High Tiering
Reach trucks are often used for high tiering, which involves storing material in multiple tiers high off the ground.

Potential Hazard:
  • Overloading
     
  • Tipover
Requirements and Recommended Practices:
  • Set the heaviest loads on the bottom tier.
     
  • Set the lightest loads on the top tier.
     
  • Reduce the load below the capacity of the reach truck as the mast is fully extended.
     
  • Slowly and carefully extend the reach mechanism forward when depositing the load on the top tier.
     
  • Use extreme care when tilting a load forward or backward, particularly when high tiering. [29 CFR 1910.178(o)(6)]
Reach trucks maximize maneuverability in narrow aisle.

Triple reach extends 23 feet high. The lightest loads are placed on the top tiers.

Reach mechanism extends forward to deposit load on top tier.
