The term comes from the days of sailing ships, when a rigger was a person who worked with rigging, that is, ropes for hoisting the sails. Sailors could put their rope skills to work in lifting and hauling. In an era before mechanical haulage and cranes, ropes, pulleys and muscle power were all that was available to move heavy objects. A specialized subset are telecommunication riggers, entertainment industry riggers. In time, rigging became a trade in itself, giving rise to modern usages with some original terminology remaining, with its roots all but forgotten.Riggers attach loads of equipment to cranes or structures using shackles, cables, chains, clamps or straps, employing pulleys, winches, lifts or chain hoists (aka chain motors). Quick load calculations are necessary for each load and engineering principles are always in play. Riggers use various suspension techniques to get their load around obstacles on a construction site or loading dock or event site to the desired location and height.A person that hooks heavy material to cranes using wire slings, hooks, chains, and straps. This peson must be skillful and knowledgeble. If done improperly, loads will fall, buildings will crumble pick up trucks will be impaled with steel beams, and people may DIE get the picture? Riggers dont appear to be the sharpest tools in the shed. Most dont know textbook algebra, but they can tell you what a 5/8 choker can lift at a 60 degree angle. Riggers give hand signals to cranes that fly the material through the air. Contrary to popular 'urban belief' that riggers take it up the ass, I think if you tried to mount a true rigger, you would find a nice piece of red iron sitting where your front seat used to be If, say, a construction job needs a crane to move heavy concrete pipes from one side of the lot to the other, it's not a simple operation. Done wrong, the pipes could slip free, or the crane could overbalance. A rigger has the expertise to see the operation goes smoothly.

The rigger knows how to attach cables or ropes to the load. That includes knowing the right hitches to tie, and the load they can support safely.
Riggers can recognize any hazards associated with a lifting and moving job.
A rigger can figure out where the center of gravity has to be on a load to keep everything stable.
They can signal to communicate their meaning to other members of the crew.
Riggers can use different types of rigging equipment such as slings, shackles, chokers and winches.
They can move heavy equipment through confined spaces safely.
A rigger can tilt, dip or turn suspended loads to avoid obstacles or hazards such as overhead power lines.
Riggers dismantle, clean and store rigging equipment after use.
A rigger must comply with all regulations and safety requirements.Many riggers don't start out specializing in rigging work. Instead their initial skilled trade may be as an electrician, carpenter, millwright, mechanic, laborer, mason or longshoreman, among other jobs. Employers may be open to hiring a novice rigger who can learn the job under an experienced mentor, provided the rookie meets some basics:

Has a high school diploma or GED.
Is physically able to stand for half the day, lift up to 50 pounds, go up and down ladders and to function for hours outdoors under the hot sun.
Is able to learn the use of rigging tools and read plans.
Is able to drive lifting equipment.
Is skilled with power tools.
A given employer may have different requirements.The federal Occupational Safety and Health Administration says the rigger in charge of work such as hooking, unhooking or guiding a load must meet OSHA's qualifications. That includes either certification or experience to manage and solve problems with rigging loads.

While some OSHA job standards are precise and detailed, rigging is an exception. There's such a variety of loads and challenges, OSHA says that "qualified" depends on the job; a rigger who's qualified or even certified for tandem lifts, say, may not be qualified for multiple lifts or to use custom rigging equipment.
