What type of rigging component can be used between two cranes sharing a load that cannot be lifted individually?

The spreader beam or lifting beam is specifically designed to handle loads between multiple lifting points, distributing the weight evenly and minimizing stress on the load. When two cranes share a load that cannot be lifted by either crane individually, using a spreader beam facilitates balanced lifting by connecting the two cranes with a beam that ensures stability and control. This type of rigging component allows for optimized load distribution, enabling safer handling of bulky or awkwardly shaped objects.

In contrast, other options like a hook, chain hoist, and fixed pulley are typically designed for single points of attachment or for lifting without the necessary capacity to distribute weight between two cranes effectively. A hook is merely a fastening device, while a chain hoist is meant for raising or lowering loads via a single point. Similarly, a fixed pulley changes the direction of force but does not aid in distributing the load across multiple lifting points. Thus, for the scenario where two cranes share a load, the spreader beam is the correct choice for safe and efficient rigging.
