Tandem shifting with cranes carries some inherent hazards, but it can be effective when two cranes operate together to lift and transfer cargo. These risks include the following:
Crane operators must coordinate with each other. Inadequate or miscommunicated movements might cause uncontrollable movements, which can endanger workers and the cargo.
2) Load Imbalance:
A load imbalance could result from the cranes not lining up perfectly. This could lead to the weight swinging, which could cause accidents, damage to the load, or injury to people and neighboring structures.

3) Equipment Compatibility:
It is crucial to guarantee that the two cranes have the same capacity, design, and technology. If they are not compatible, this could lead to an unequal distribution of the load and jeopardize the stability of the lifting operation.
4) Windy and environmental factors:
Tandem lifting is more vulnerable to weather and wind-related factors.
5) One-Side Load:
Load shifting to one side or rigging failure at the time of tandem lifting.
6) Rigging and Slings Failure:
Failure to collapse the crane during tandem lifting or rigging bed technique is related to slings and rigging.
7) Lifting Plan Calculation Above 80%:
The term “high-risk” in tandem calculations refers to lifting above 80%.
Professionals with the necessary skills should execute this tandem lift. Standard lifting carries a significant risk element; therefore, you should always check before beginning any lifting technique.
