![]() ![]() Lifting more than one container at the same time has become popular over the years. Lack of expert supervision: The whole tandem lifting operation must be watched out by an expert.To avoid an asymmetric distribution of weight, it is crucial to have the plans of the part that will provide the weight and its center of gravity. Not symmetrical objects/weights: The load could be higher on one side and exceed the rated capacity of the hoist on this side.Lifting plans take special attention to this aspect to avoid accidents. Side loading: Coordinated crane movement is maybe the core task in tandem lifting.Assigning the responsibilities of competent persons (operators, riggers, stevedores, etc).Planning beforehand is thus required to avoid accidents, taking on account factors as the following: Safety measures are the biggest concern on tandem lifting. Helping other cranes: Distributing weight among several cranes makes accidents less likely when moving heavy cargo.This and the awkward shape of vessels makes them a challenge in terms of lifting. Moving ships: fuel may move on the inside, changing the center of gravity.Some secondary reasons to require tandem lifting are: When, due to the weight or dimensions of the piece to be lifted, it is not possible to do it with a single crane. Tandem lifting is the process of lifting loads too big or too heavy for just one crane ![]()
