Crane Lifting (Vertical Installation) - Tandem Lifting of 2 Cranes, where Crane 1 will lift on its Main Lifting Points then Crane 2 will lift from the Load Tail Point. Where at most, equipment being lifted is at horizontal position, 2 Cranes will be Upending the load to Vertical Position.   

Crane Lifting (Horizontal Installation) - Tandem Lifting of 2 Cranes by lifting the load @ 2 lifting points and                                                          inserting the trailers under for loading.

To make a lift plan for tandem lifting

First thing is to consider is the area of lifting ie, positioning and selection of crane, near by utility services and buildings, ground conditions, Wind speed etc..

Secondly consider the load which is going to be lifted ie the weight, complexity, irregularities etc...

Thirdly consideration should be given of the lifting tools and tackles, ie the third party certificate for lifting, slings and shackles, wire ropes etc..

and finally we need to consider the competency of the lifting team Effective communication must be established and maintained between all people involved in a tandem lift.
