Who does the link protect when an insulated link is used on a crane hook?

The use of an insulated link on a crane hook primarily serves to protect ground personnel. This type of link serves as a barrier that reduces the risk of electric shock from electrical systems that may be present in the surrounding area. When energized overhead lines are in proximity, ground personnel are at risk if the crane or the load comes into contact with those lines. The insulated link helps to ensure that the electrical potential does not reach the hook or the load being lifted, thereby lowering the risk for anyone operating nearby.

By isolating the hook and the lift from any potential electrical hazards, the insulated link plays a critical role in safeguarding those who are not directly involved in operating the machinery but who may be working in the area. This consideration for safety is paramount in environments where there are risks associated with power lines or other electrical infrastructure.
