What is the preferable method when lifting and rigging?

Determining the exact weight of the object is crucial in lifting and rigging because it ensures that the lifting equipment being used is rated appropriately for the load it will bear. Knowing the precise weight allows for proper selection of hoists, slings, and other rigging equipment, thereby minimizing the risk of accidents, equipment failure, and injury to workers. It allows for safe calculations and provides guidance on how to distribute weight evenly, ensuring stability during the lift.

Using approximate weights or guessing can lead to dangerous situations, as it may cause operators to underestimate the load, use inadequate lifting equipment, or improperly rig the load. Choosing the lightest side of an object does not consider the actual weight and can result in imbalances that compromise safety. Therefore, accurately determining the weight of the object is the best practice in lifting and rigging operations.
