For each CROP upon which another is being stacked (bottom CROP), ensure all remov-
able blockers (1) are secured in their stowed positions (6) at the sides of the deck.
For the CROP upon which another is being stacked (bottom CROP), push up and turn han-
dle (3) on all four corner twistlocks (2) to the UNLOCKED position. The twistlocks raised
to the UNLOCKED position act as guides for CROP being stacked (top CROP).
For the CROP upon which another is being stacked (bottom CROP), ensure the tiedown
ring immediately adjacent to each of the four twistlocks is in its lowest position, not pro-
truding above the deck.
Remove three web straps (4) from CROP stowage boxes (5) located in the deck of the last
CROP to be stacked (the one which will end up on top).
Ensure web straps are wrapped a minimum of three times around ratchet of web strap.
Failure to comply may result in web strap being released and CROP may fall, causing
severe injury or death to personnel.
