Cranes and associated rigging equipment must be inspected regularly to identify any existing or potentially unsafe conditions.
The most common types of accidents related to cranes and such equipment include contact with power lines, loads getting dropped, and boom collapses. These rigging problems can occur if the cranes are not inspected often enough, which is an essential part of good maintenance.
It is necessary to fix any problem even it means interrupting work, because this is still preferable to injuries (or worse, fatalities), considerable material losses, and unflattering media coverage.
