The VAC-U-MAX Bulk Bag Unloader was specifically designed to provide
an easy, clean and economical way to discharge the entire contents
of bulk and semi-bulk bags, especially when the material is less
than free-flowing.
Bags can be placed in the unloader by fork lift, hoist or crane
from floor level. An integral hoist on a monorail can be furnished
if desired. Standard arrangement includes a bag frame to which the
suspension loops of the bag can be attached while the bag is resting
on the floor. The bag frame is then raised and positioned so the
hooks on the frame engage a counter-balanced suspension frame in
the superstructure of the unloader. When lowered, the bottom of
the bag rests on a sealing ring in the unloader bed and the tension
on the bag loops keeps the bag upright. Optional pneumatically operated
actuator petals massage the lower portion of the bag to promote
material flow toward the center of the bag.
