7-16. STACKING/LOADING THREE FLATRACKS ON PLS TRUCK OR TRAILER (CONT).
Flatrack weighs 7,300 lbs (3,312 kg). Use a suitable lifting device or forklift to lift flatrack.
Failure to comply may result in injury or death to personnel.
Flatracks have two sets of forklift pockets. If lifting one empty flatrack, use the inside set of
forklift pockets. If lifting a loaded flatrack or lifting multiple stacked empty flatracks, use the
outside set of forklift pockets. Always use the forklift pockets of the lowest flatrack.
Forklift forks must be a minimum of 70.0 in. (177.8 cm) in length.
With the aid of two assistants and using a lifting device, position upper flatrack (6) over lower flatrack (3)
so that ISO corner castings (7) are aligned over the raised twist locks (5) of lower flatrack (3).
When stacking flatracks, ensure that twist locks of lower flatracks are aligned with ISO
corner castings of upper flatracks. Failure to align twist locks and ISO corner castings
could cause damage to equipment.
Lower upper flatrack (6) onto lower flatrack (3).
Twist locks must be completely locked in place. Ensure that twist locks have snapped fully into
place. Failure to completely lock twist locks could cause serious injury or death to personnel.
Sliding handle from stowage box may be used if locking handle is difficult to turn.
Reach through openings (8) of ISO corner castings (7) of upper flatrack (6) and rotate locking handles (4)
of four twist locks (5) 45 degrees in either direction to lock both flatracks together.
Visually inspect four twist locks (5) to ensure that stems (9) have engaged ISO corner castings (7) of
upper flatrack (6).
Repeat Steps (1) through (9) for stacking the third (top) flatrack.
