What is the purpose of a pry bar in rigging?

A pry bar is primarily used in rigging and hoisting to lift a load slightly by being inserted under the edge of the load and then pushed down. This tool takes advantage of the principle of leverage, allowing an operator to raise the load enough to set it on a higher surface or provide room for additional rigging materials. This is especially useful in scenarios where a load needs to be repositioned or adjusted slightly without lifting it completely off the ground.

The other options do not accurately describe the primary purpose of a pry bar. For example, using a pry bar to secure a load during transport misrepresents its function, as securing typically involves straps or chains rather than a lever mechanism. While a pry bar can help in aligning heavier loads, it doesn’t create a mechanical advantage for lifting, which is the role of different tools such as pulleys or hoists. Lastly, adjusting the height of a suspended load typically involves lifting mechanisms rather than the use of a pry bar, which is limited to making small adjustments or lifts.
