As an operator or supervisor working with overhead, gantry or similar cranes, you realize what powerful tools these machines are. Unfortunately, the very power that makes them so useful also makes them dangerous. In recent years there have been about 50 crane accidents a year in the U.S. A number of these accidents have been fatal. Such accidents are preventable, however. By properly maintaining and operating the cranes with which you work, you will protect yourself and your coworkers. Remember, your safety is in your hands.
