Multiple crane lifts are among the most technically complex lifts to plan and execute. It’s always important to properly plan any lift, but even more so when there are several cranes involved. It figures – right? Double the equipment, double the personnel, double the consequences! The complex nature of lifts involving multiple mobile or crawler cranes makes them particularly hazardous. When there are two or more cranes involved in an incident, the impact and outcome of the incident is often magnified. Several of the most high-profile crane accidents of recent times have been those involving multiple cranes (also referred to as tandem lifts).
