When experiencing uncontrolled movement while operating a tower crane, what should the operator do?

In the event of uncontrolled movement while operating a tower crane, engaging the emergency stop is the appropriate and safest response. The emergency stop mechanism is designed to immediately halt all crane operations, which helps to prevent accidents or further complications caused by the crane's erratic behavior.

This action gives the operator a moment to assess the situation safely, ensuring that both personnel and equipment are protected from potential hazards. Quick disengagement of the crane’s movements is crucial in preventing any collisions or damage that could arise from the crane's uncontrolled actions.

In situations of uncontrolled movement, options such as increasing the load or lowering it slowly could potentially worsen the problem, leading to instability or accidents. Calling for assistance might be necessary afterward, but stopping the crane's movement takes priority to ensure safety.
