Part 6 Cranes, Hoists and Lifting Devices

Section 68 Load weight

The weight of the load being lifted is perhaps the most critical piece of information needed to conduct a lift safely. Everyone involved in the lift must know this in order to carry out their duties. The rigger must be able to apply the appropriate type, number and configuration of slings and other attachments. The operator must be able to place the lifting device and adjust boom lengths and angles to the appropriate configuration. The person in charge of the lift, such as the lift coordinator, has ultimate responsibility at the lift site for the lift’s safe execution. Depending on the complexity of the lift, a lift engineer or rigging specialist may be required to design the lift.

The total weight of a load is the sum of the actual load weight, the weight of the hook and block, and the weight of slings and other lifting attachments. These weights can be determined in information provided by manufacturers, engineering specifications, or calculations performed by a competent person.
