When should the load chart be consulted during a lifting operation?

The load chart should be consulted before lifting a load to ensure safety and compliance with operational limits. This crucial step enables the rigger or operator to determine whether the crane or lifting equipment can safely handle the intended load, taking into consideration its weight, the configuration of the rigging, and the conditions of the lift such as radius and lift height.

By reviewing the load chart beforehand, one can establish the maximum allowable load based on the equipment's specifications and the overall configuration being used, which is vital for preventing overload situations that could lead to accidents or equipment failure. Consulting the load chart at this stage helps in planning the lift correctly and ensures that all safety protocols are adhered to, making it a fundamental part of the pre-lift inspection process.

Other options suggest assessing the load chart during or after the lift or under specific circumstances, which would not provide the necessary foresight to avoid potential hazards associated with lifting heavy loads.
