Standing up the base frame
Once the frame is standing upright
it is important to note the
orientation of operator access and
bag load side. With a standard
configuration the bulk bag is
loaded from the same side as
operator access.
Ensure that a safety strap is attached to the frame
and the fork lift. It must be at located at least 12
inches SHORTER than the fork length to assure
the frame will be secured to the fork lift truck.
Use a suitable fork lift truck that is capable of lifting to
a height of no less than 8 feet. Raise both ends of the
frame just enough to slide out the pallet.
Insert Forks centrally under the horizontal cross
bar that is opposite the foot pads as shown.
Avoid making contact with the Safety Frame.
Raise forks while driving forward slowly until
the balance point is reached.

Locating the Base Frame
Ensure that the foundations are suitable to withstand the full load of the frame. If applicable, see the
Load Cell information located in the ‘Optional Equipment’ section of this manual.
Anchoring the Base Frame
Anchor the base frame to the foundation using the appropriate SAE Grade 5 (or better) hardware.
Flexicon®recommends that the customer consults with a civil engineer or local professional engineer
to evaluate floor substrates and specify the type and depth of floor anchors required. (16)
bolts/anchors are typically needed.A standard FLEXICON® BULK-OUT®Bulk Bag Discharger base
frame is shown below in Figure 6. It can be assembled into either a BFC or BFF Frame. There is a
removable cross brace on the operator access side which can be unbolted and removed temporarily
to allow for easier installation of other components that are to be located inside the frame such as a
floor hopper or similar items. The brace is to be bolted back in place after the component(s) has
been installed inside the frame.
