What is the function of a pry bar in lifting operations?

In lifting operations, a pry bar serves the important function of allowing a slight lift of a load by pushing under it. This tool is particularly useful in scenarios where heavy objects need to be slightly elevated to facilitate placement or positioning. When inserted under a load, the pry bar leverages mechanical advantage, making it easier to raise the load even just enough to insert additional support or rigging. This function is crucial in preventing sudden shifts in load distribution, which could pose risks during handling or moving.

The other options do not accurately reflect the primary function of a pry bar. It does not serve as a tool for lifting loads vertically, which typically requires hoisting equipment such as cranes or hoists. While stabilization of a load is important in lifting operations, this is not the main purpose of a pry bar. Similarly, securing loads during transport typically involves different tools and methods, such as straps or shackles, which are specifically designed to hold loads in place.
