What is the purpose of a "spreader bar" in rigging?

The purpose of a "spreader bar" in rigging is to distribute the load evenly and prevent damage. This device is commonly used in lifting operations to manage the stress and forces acting on the load being lifted. By spreading the load out across a wider area, the spreader bar helps minimize the risk of overloading any single point or section of the load, which could lead to structural failure or damage.

In terms of usage, a spreader bar allows for safer handling of delicate or irregularly shaped cargo by ensuring that the lift is stable and balanced. This is particularly important when lifting heavy equipment or materials that may have a tendency to sway or shift during the lifting process. By maintaining an even distribution of weight, the spreader bar enhances overall safety for both the load and personnel involved in the lift.

This approach to load management is essential in rigging operations, where protection of the load and enhancing operational safety are primary concerns.
