Definitions A load whose weight is greater than the combined weight of a Heavy Load singic spent fuel assembly and its handling tool. ( > 1500 lbs.).
The safest path that will be followed when a heavy load is being Load Path moved by a crane or hoist.
Monorail - A specific fixed structural rail, usually an I-beam, on which a lifting device is placed to make lifts on a specific piece of equipment in a predetermined direction.
A projecting arm attached at a pivot point on which a hoist travels Jib lifting only equipment located directly under the jibs radius.
