What is the basic principle of rigging?
Rigging is the process of moving heavy loads with slings, chains, hoists, and other special tools. The equipment used for lifting and moving loads is also called rigging.
What are rigging techniques?
Rigging- Methods of slinging hitches:
- CHOKER HITCH.
- Sling passes through one end around the load, while the other end is placed on the hook. Load control is limited with only one sling rigged in a choker hitch.
- VERTICAL HITCH:
- BASKET HITCH:
- Sling-To-Load Angle:
Why is rigging training important?
Riggers have the knowledge required when it comes to knowing which hitches to tie and how much weight different cranes can support. They have a great understanding of a load’s center of gravity, which is required to ensure proper balance, stability, and mobility of the load at all times.
What tools do riggers use?
The most commonly used rigging tools are wire rope slings, polyester webbing slings, chain slings, and the modular lifting solution spreader beams.
How is rigging capacity calculated?
You will need a sling or slings with a rated capacity equal to or greater than the rated capacity required for the corresponding rigging technique. Minimum weight on each leg: 0 lbs. Maximum weight on each leg: 0 lbs….To calculate the load on a particular sling leg proceed as follows:
| Leg Angle | Load Factor |
|---|---|
| 30° | 2.000 |

What is Rigging Equipment?
- Wire Rope Slings. Wire rope slings are available in a range of lifting capacities, providing users with a strong and flexible solution for performing lifting operations.
- Polyester Webbing Slings.
- Chainslings.
- Spreader Beams.
What do you need to know about rigging a lift?
Once a lift has been planned and approved, the appropriate rigging equipment, including slings, shackles, turnbuckles, and the crane itself, must be selected, inspected, and connected correctly prior to beginning the lift itself. The following items must be checked and confirmed before selecting rigging components: •Weight of lift
What do you need to know about crane rigging?
The following items must be checked and confirmed before selecting rigging components: • Weight of lift • Center of Gravity • Lift points • Crane capacity • Speed, height, width, and length of lift • Wind, temperature, and visibility • Crane and Load foundation ratings • Sharp corners and angles on load • Sling angles • Load angle factor
What kind of industry does rigging work in?
Rigging is a complex practice that’s used across many industries including mining, construction, steel, automotive, and shipping, to name a few. When it comes to rigging, there are a lot of terms that those familiar with it will use regularly.
What is the subject area of a hoisting and rigging Handbook?
The Subject Area contains guidance that must be used in order to plan and perform a lift safely. This instructor handbook incorporates the Subject Area’s requirements, as well as information from the Department of Energy’s (DOE’s) Hoisting and Rigging Manual and ANSI B30.9. Definitions Asymmetrical load.
