What is a common use of a spreader bar in rigging?

A spreader bar is primarily used in rigging to distribute the load over a wider area. This distribution reduces the risk of localized stress that could damage the load or create an unstable situation. By spreading the load’s weight, the bar helps to prevent issues such as crushing or deformation of the load itself and ensures a more balanced lift. This capability is particularly important when dealing with items that have irregular shapes or are sensitive to pressure.

When the load is distributed more evenly, it also enhances safety during the lift, as it minimizes the chance of slippage or sudden shifts that can occur with concentrated loads. This function of a spreader bar makes it an essential tool in many lifting operations, particularly in construction and material handling, where safety and load integrity are paramount.
