Two-Yard Bottom Discharge Hopper

Item #: 322-01

VAC-U-MAX dump hoppers allow for extended vacuuming times and large-volume recovery of dry materials only. The heavy-duty reinforced containers are constructed of carbon steel with a grey epoxy finish, and are rated for 16” Hg (220” / 5500 mm waterlift) maximum vacuum. 

Compared to self-dumping (roll-forward) hoppers:

  • Bottom discharge style keeps the center of gravity close to the forklift mast and eliminates potential pinch points
  • Square shaped bottom discharge hopper reduces the footprint by 40% compared to self-dumping roll-forward hoppers
  • 40% Larger discharge opening as compared to self-dumping hoppers
  • Pull chain design with vertical lever allows forklift operator to discharge contents without leaving the fork lift
  • Inspection door which allows for easy visual inspection of contents
  • Faster, more reliable discharge angle of 45-degrees
  • Eliminates the roll-forward motion and sudden weight shift to the end of the forks
