How do you determine the weight of a load to be lifted?

Determining the weight of a load accurately is crucial for safe rigging and lifting operations. Using a certified scale or calculating the weight based on the dimensions and material density provides the most reliable method to obtain this information. A certified scale directly measures the weight, ensuring precision and accuracy, which is essential in preventing overloading a hoist or rigging equipment and maintaining safety standards.

In cases where direct weighing may not be possible, calculating the weight based on the dimensions and material density is a scientifically validated approach. This calculation allows the rigger to estimate the weight based on the precise characteristics of the load, which helps in planning the lift effectively.

Other methods, such as visual estimation or rough approximation techniques, lack the accuracy and reliability needed for safe lifting practices. Estimating visually may lead to significant errors, while rough approximations do not provide dependable loading data. Relying solely on manufacturer specifications can also be insufficient because it may not account for additional factors, such as modifications made to the load or actual material variations. Thus, using a certified scale or precise calculations is the best practice for determining the weight of a load.
