If the load would be out of sight of the crane operator if it were a single crane or single crane dual hook operation. In general, these considerations may determine when you would choose a multiple crane lift (this is not a blanket fixed set of rules): Multiple crane lifts can range from rotating a column using a lift crane at the top and a tailing crane at the bottom, to lifting a pre-assembled platform with eight cranes. Multiple crane (means a lift operation that requires two or more cranes) arrangements/methods are sometimes used on lifting jobs when physical dimensions, characteristics, mass, required movement of the load, environmental restrictions or other factors prevent the lifting operation from being performed by a single crane or single hoist. ![]() Contributed by Alice Edwards, Technical Project Engineer – The Crane Industry Council of Australia (CICA)
