Lifting & Stacking – Caisson Rings

Caisson Rings should only be stacked vertically. The first chamber should be placed on timber lengths on even and stable ground.  The maximum height the chambers should be stacked is 2 metres.

The Caisson Rings should be lifted using a 4 legged chain with universal lifting  eyes and three shortening clutches for altering chain lengths. The angle of the chain must be no less than 600. Under no circumstances should the lifting system be used to lift more than one caisson ring at a time. Lifting should be carried out slowly and steadily, avoiding all shocks and impacts.
