Uses
Cribbing is often performed as part of lifting/lowering operations. Expressions such as "lift an inch, crib and inch" and "pack as you jack" are used to remind operators of the importance of cribbing to secure and protect the load. The use of cribbing also allows for the use of a lifting device with a limited working range (such as a jack, lifting air bags or hydraulic rescue tools) as the load can be raised to the maximum range of the device, then lowered a short distance onto the cribbing, allowing another platform of cribbing to be built to raise the device and repeat the process.
Cribbing can be used to secure a load following a building collapse, vehicular accident or other event where the regular stability of a structure or vehicle has been reduced.
Cribbing is used when moving buildings in whole, or in part. Cribbing is used to raise the structure and allow the carrying vehicle to be positioned underneath, at which point the structure is then lowered onto the vehicle and the cribbing towers are removed. At the other end of the operation, the process is reversed, and the structure is lowered into its new position.
