What is Rigging – 21 Duties of a Rigger


Rigging is an action of designing and installing the equipment, in the preparation to move objects; it is a system of ropes or chains.

Rigging involves preparation and setting up a load for lifting. The person who carries out rigging activities is called a Rigger.
