Answer 1

Two other errors that often lead to trouble are:

• Cranes buckling or collapsing.
• Improper employee training

Discussion:

• Cranes buckling or collapsing. Cranes have weight limits so that they do not tip over. If the weight limits are exceeded, the crane can tip over or the boom could collapse. A major cause of this is improper crane assembly in which case the crane does not have the proper wood or metal blocking supports to stabilize the load the crane is carrying, the load could move and cause the crane to collapse.

• Improper employee training. Crane workers must be properly trained in the use of cranes and complete technical courses on the proper operation of cranes. Employers also need to ensure that workers are warned of crane dangers and maintain a safe distance between the crane operation and work performed by other workers.
