The frame of this fork-loaded bulk bag unloader is fabricated and delivered in three sections that bolt together. Note that the cross supports of all sections are located in the rear of the frame. Typically, either epoxy anchors or sleeves are installed in the floor to anchor the base via the 12 holes in the mounting feet of the frame. Next, place bolts and washers in the four holes at the bottom of the top section.
All four bolts are secured with nuts and washers, then tightened well to connect the top two sections. Returning to the base, the load cells must be rotated to the top of this frame section.
When reattaching U bolts, use the outer holes of the mounting plates as the inner holes are used to attach the midsection on top.
Be sure to align the load cell evenly from side to side, making adjustments to the cell and U bolts as necessary. Be sure that no wires are running between the U bolts and the frame, and place the wires into the guide clips.
Once all four load cells are complete, place wooden blocks on each corner of the base section, making sure not to cover the drilled holes and so that the tops of the blocks are just above the top of the load cells.
Align the top and middle sections with the base, placing bolts in the holes at each corner. Then, lower onto the wooden blocks. Use a washer and nylock nut on each bolt and hand tighten. Now, slightly raise the middle and top sections, remove wooden blocks, and gently lower onto the load cells.
Attach the frame to the top of each load cell with U bolts using the interior holes on the load cell plate. Tighten with washer, lock washer, and nut.
Finer height adjustment can be obtained by using either of the pin placements in the receiver arms. Readjustment may be necessary once the bag is attached to the Bag Lift 500 Adapter. The system is now ready for use or connection to a downstream system.
