What risks occur when lifting against suction under panels being raised?

When lifting against suction under panels being raised, the primary risk involves the potential for overloading or shock loading the crane or equipment. This situation arises because the suction creates significant resistance that can suddenly release if the panel becomes dislodged. When this happens, the load can drop unexpectedly or shift, which may result in sudden forces acting on the crane and its components. Such dynamics can lead to shock loading, where the load experiences rapid changes in force, potentially exceeding the equipment's rated capacity and causing structural failure or loss of control.

Understanding this risk is crucial for safe lifting operations, as proper risk assessment and mitigation strategies need to be in place to avoid accidents. Other factors, like the wear and tear of cables or increased lifting speed, are important considerations in lifting operations, but they do not directly relate to the specific risks of suction under panels being raised in the same way as overloading and shock loading do.
