What is the primary purpose of an equipotential zone in crane operation?

The primary purpose of an equipotential zone in crane operation is to ensure electrical safety for workers. This zone is established to create a uniform electrical potential across a designated area, minimizing the risk of electric shock to workers who may be operating around electrical equipment or during crane operations. By grounding the equipment and ensuring that there are no differences in electrical potential within the zone, the risk of hazardous situations caused by stray currents or electrical faults is significantly reduced.

In addition to enhancing worker safety, the equipotential zone helps in compliance with safety regulations, thereby fostering a safer working environment on construction sites. This is crucial since cranes often operate in environments where electrical hazards may be present, whether from overhead power lines or electrical equipment used on-site. Maintaining a safe operational area where workers are protected from unintended electrical hazards is essential in preventing accidents and injuries.
