Be certain that the ground, floor, or other surface is capable of supporting the combined weight of the crib
structure and the load to be supported.Never build cribbing on loose or unstable ground.
Never exceed the maximum capacity of the cribbing.
A-Frame Outriggers/Stabilizers: Take special precautions when deploying A-frame outriggers onto any
cribbing set-up.Lateral forces need to be accounted for to avoid potential toppling of the set-up.
ProStack cribbing should be constructed by trained and experienced personnel under the direction
of a qualified technician or engineer trained in cribbing applications and safety.
Do not use cribbing if it is cracked, split, warped, or damaged.
Never use chemically damaged cribbing.
Do not allow personnel to climb or hang onto cribbing.
