Rigging and hoisting of steel members and materials are essential parts of the steel erection process. However, in addition to the dangers usually associated with cranes and derricks, steel erection can also create hazards, such as suspended loads over employees.

Cranes are one of the most versatile, powerful and important pieces of construction equipment, accomplishing heavy lifting and moving tasks more efficiently. They are also one the most dangerous pieces of equipment, creating fall and struck-by hazards as heavy, suspended loads move over large areas. Employees working with and around cranes need to understand these hazards, as accidents with suspended loads are serious and potentially fatal.

Crane accidents are a leading cause of death and injury on construction jobs. Workers may be at risk to being struck by loads or equipment or getting caught in between moving equipment, materials and power lines.
