What are the signs of an overloaded tower crane?

Recognizing the signs of an overloaded tower crane is crucial for ensuring safety and operational efficiency. Unusual sounds, deformation, or instability are key indicators that a tower crane may be experiencing an overload situation.

When a tower crane is overloaded, it can produce abnormal noises due to strain on its components, including the hoist mechanism and structural elements. Deformation refers to any bending or warping of the crane’s structure, which indicates that the crane is being pushed beyond its designed capacity. Instability may become evident through swaying or difficulty maintaining a stable position, which can compromise both safety and functionality. These signs are critical because they can help operators identify potential hazards before they lead to accidents or equipment failure.

In contrast, normal operational noises and vibrations, consistent load weight indicators, and stable lifting of maximum capacity loads do not indicate an overload situation. Specifically, consistent load indicators and stable operations suggest that the crane is functioning within its safe operational limits.
