FormPak’s line of heavy-duty bulk bag unloaders will discharge practically
any material. If it can be unloaded from a SuperSack® – we
can do it.
Our unloader incorporates the “live bottom” technique
with an isolated all-SS hopper and a 1500 pound force industrial gyrator.
If we test your material in our lab, we will guarantee discharging from your SuperSack®.
(see details below). SuperSack® unloaders
are available with any type of take away conveyor, as well as optional features
like access doors, downspouts, iris valves, and downstream process equipment
to condition and control your product. We can even set up your unloader as
a loss-in-weight batching system.
Fork Truck Loaded Machine
Our fork truck loaded machine is our most popular, and is a very cost competitive,
fully integrated system. It represents the best all around, competitively
priced, industrial duty unloader, with features like easy bag height adjustment,
offset receiver arms for straight in fork truck loading, and heavy structural
frame with two part epoxy paint.
Hoist and Trolly Unloader
The hoist and trolley unloader allows staging SuperSacks with pallet jack.
An integral I- beam with a pendant controlled hoist and trolley, provides
quick and reliable loading with one operator.
Half Frame Units
We also offer half frame units for applications where existing hoists are
available, or simply wish to support the bag with a fork lift. Another option
is our retrofit kit to incorporate the “live bottom” gyration
to an existing static unloader or frame. We test for free.
- Send us your SuperSack of material for a free unloader
test.
- We offer free testing and evaluation of bulk bags in our unloaders.
- When we successfully test your material in our lab, we will guarantee the
performance of our equipment for that material.
- All you have to do is send
us a full and empty Super Sack to our lab in St. Louis (freight costs to
and from our lab are the responsibility of the customer).
- You are encouraged
to witness these tests, but we can provide video and photographs as well
as a written report of results if your time does not permit
