Cranes, hoisting apparatus, (such as chain falls, winches, and marine railways)
and their accompanying rigging gear, are used to move and lift materials and
equipment during shipyard operations. Moving heavy loads in
congested areas increases risk of injury.
Figure 1: Illustration of general working conditions on vessel with the gear and equipment for rigging and materials handling.
Rigging methods and equipment
are used to attach heavy loads
to lifting devices such as cranes, derricks, or chain
falls. Rigging equipment may include: rope, chains, or synthetic webbing
slings, which connect the loads to lifting machinery by means of hooks or
shackles. Inadequate rigging methods or components may result in the load
detaching and injuring workers.
Serious injuries may result from:
- Equipment failure
- Improper use of equipment
- Getting caught between or struck by loads or rigging gear
- Getting struck by loads or rigging gear
