OK, we’re going to demonstrate hanging a bag on the bulk bag unloading device. So, we’ll lower the lifting adapter until it’s just barely touching the top of the bag.
Now, each of these lift loops is carefully wound into the labyrinth holder. These are designed so that the bag loop can’t come out. Obviously, this bag’s empty, but even when it’s full, this bag could hop around accidentally, it’s captured and the lift loop can’t come out of there.
Even should one break, the other three will continue to hold the bag. So carefully put all four in and once they’re securely in place then you can lift the bulk bag.
