Rigging Equipment Glossary: Common Rigging Terms You Should Know
Rigging is a complex field, and experienced riggers rely on a comprehensive knowledge of rigging equipment, principles drawn from engineering and physics, and extensive safety regulations and standards. The terminology and concepts underlying rigging can be challenging to get to grips with.
Rigging Equipment
Rigging is the equipment used to lift, suspend, support, tow, or tie down a load or the use of that equipment to do the same. It includes chains, wire ropes, slings, and the equipment used to connect these to a load, vehicle, supporting structure, or lifting machine such as a crane or hoist.
The Rigging Team
Depending on the job, the rigging team may be one qualified rigger or a group of professionals with varying responsibilities, including riggers, spotters, lift directors, and site supervisors. For overhead lifts, these roles and responsibilities are defined by OSHA and ASME in standards such as ASME B30.3 and ASME B30.5.
Rigging Safety
The minimum breaking load (MBL) is the maximum load rigging equipment can be exposed to until it breaks or fails. Rigging equipment should never be exposed to loads approaching the MBL. Instead, a safety factor is applied to arrive at a safe working load limit (WLL) or rated capacity (RC), as explained in the following entries.
Rigging Standards and Regulations
The American National Standards Institute (ANSI) oversees the development of voluntary standards for almost every industry in the U.S., including rigging standards. ANSI does not create standards; it accredits and works with other organizations, including ASME, while providing a general framework for standard development.

What is rigging equipment?
Rigging equipment referrers to the devices and elements used to lift and manoeuvre objects safely, as part of a planned system implemented by a team of riggers.
Why should rigging equipment be sourced?
The rigging equipment itself should also be sourced from reputable suppliers, in order to ensure that the products are of a suitable standard and quality. In order to maintain this quality, the items should then be regularly tested to ensure that it continues to meet safety standards.
What industries require rigging equipment?
Industries which often require the services of rigging equipment include construction, engineering and event staging. Like all lifting operations, hoisting and rigging should be performed with public and employee safety as a primary focus.
What happens to the sling leg angle when the sling angle decreases?
As the sling leg angle decreases the force on the sling leg increases. The load factor for the sling angle is taken from a load factor chart.
What is the force of pull on the leg of a sling?
The force of pull on the leg of a sling varies with the sling angle, so the forces on the sling need to be determined for the specific sling angle used. The sling angle is the internal angle of the sling. As this angle decreases the sling leg load increases.
What is the next step after verifying the load weight?
After verifying the load weight, the next step will be to calculate the lifting capacity required.The rated lifting capacity of the sling and shackles must be greater than the weight of the load to be lifted.
How to calculate sling load factor?
If you do not have a load chart, you can calculate the sling load factor using the ratio of the sling length divided by the sling height. For this example, we will use a sling length of 28 feet and a height of 20 feet. In this case the sling load factor would be:
What equipment is used in overhead lifts?
Critical equipment used in the lift include the crane or hoist, crane hook, and the slings and shackles that connect the hook to the load. There are several ways you can easily identify the weight of a load.
What is the purpose of accurate load weight?
An accurate load weight determines the specifications of the equipment used in a lift. Critical equipment used in the lift include the crane or hoist, crane hook, and the slings and shackles that connect the hook to the load.
How to identify load weight?
There are several ways you can easily identify the weight of a load. Equipment or fabricated components delivered to a work sites should have the load weight marked on the component. Look for permanently stamped or tagged weight indicators. Loads that are regularly lifted will have known load weights.
What is rigging?
Rigging is the technology used by rigging technicians of your audio visual provider’s crew to suspend equipment such as speakers, lights, draperies, microphones, LED screens, etc. from the ceiling or truss structures (yes, we will get to those, too, in a minute) for live events. Rigging can be constructed of various materials, depending on the kinds of equipment you want to attach or suspend from it. Some of the most common materials used for rigging construction include truss systems made of scaffolding or crossbeams, on which rigging equipment such as steel cables, chains, hoisting equipment, small motors etc. can be attached.
Why do you need rigging for an event?
Aside of practical purposes, so as to provide the best audio visual set-up that fits your event’s needs, rigging also gives a more professional look and tone to your event and also gives your attendees more room to have fun. In addition, whoever you have present on stage will have more room to perform.
What is truss?
We have arrived at the term that usually has non-AV professionals scratching their heads. Trusses are usually made of a web of joined triangles, hinged together to facilitate for more even weight distribution, as well as comprehension and management of changing tension, without shearing or bending. Their most common use is for making bridges, towers, roofs, and for stage rigging. The most common material that trusses for events are made of is aluminium, which is not only durable but also lightweight to make rigging a much easier job.
What is truss system?
Truss systems typically comprise of the metal framings hinged to the ceiling by the rigging points and motors. From there, other production equipment such as the lighting, projectors, screens, cabling, speakers, microphones etc. are attached. Some popular truss systems include:
Why use trusses for projection?
Incorporating trusses for your sound projection, lighting, stage and theater rigging efforts provides for greater flexibility (especially around the main stage area) when planning your event. Truss systems are pivotal for enhancing audio, video, lighting, motion capturing, staging, as well as other creative components.
How high should a stage rig be?
This way, you can get more vibrant and creative stage rigging, as well as other benefits. Usually, teams will need to rig from 10 feet above the stage for the best results. One excellent way to avoid the drawbacks of choosing the wrong venue is to take your AV provider along when selecting a venue. With their expert insight, they can quickly tell you what kind of rigging the venue will accommodate, what types of truss should be used, etc.
What is the first thing to consider when deciding what style of stage rigging, truss systems,?
A lot comes into play when deciding what style of stage rigging, truss systems, and rigging equipment would be appropriate for an event. The first thing is safety, and then other key considerations such as the venue, number of guests, cost, physical infrastructure, etc.
