Rigging Training Workshop: Lift and Turn
A fairly simple method to upright a load is to lift with a crane while moving horizontally. In our March 1996 Issue, we discussed the use of a step block to help avoid "flop-over" or shock load if the load's CG passes its tipping axis. In this workshop you are asked to determine the loading in all five stages of lifting.
