A rigger is a person that specializes in the lifting and moving of extremely large or heavy objects. There is no place for shortcuts when performing this important job. Riggers must use approved rigging hardware and know how to apply standards that apply to each situation. They need to be able to select proper hardware, know how to calculate the weight of an object, and determine the center of gravity of the load. This course covers all the fundamentals, including necessary training and qualifications, hand signals, general standards, rigging components, rigging hook-ups, inspection and controls.
- Lesson 1 covers necessary training and qualifications. The following questions are answered as they pertain to training requirements, which may also be governed by your local or regional government's occupational health and safety regulations: Who can perform the rigging of loads for lifting? Who is responsible for your safety? What are the restrictions on persons rigging and lifting loads? What additional training might be needed for rigging complex loads?
- Lesson 2 covers general requirements. Before trainees can learn how to perform common rigging and hoisting tasks, they must first understand the safety factors that must be considered before rigging and hoisting a load. They also need to be able to assess a load to determine its weight and center of gravity. They are advised on how manufacturers indicate the rated working load of different components of rigging hardware and what the "rated capacity" of a rigging component is. They also learn how the conditions of use affect the rating of rigging hardware and the hand signals to use once the load is in transit.
- Lesson 3 explains the rigging components. There are many pieces that make up the complete rigging puzzle, and each one is important. As the old saying goes, "A chain is only as strong as the weakest link." This is literally true for all rigging components. This lesson covers each piece in detail, including hooks, shackles, wire rope, synthetic slings, chains and basic accessories.
- Lesson 4 is all about hooking up loads. Once the load has been assessed and appropriate rigging hardware has been selected, components are assembled into a rigging hook-up or hitch. The types of basic rigging hitches are covered in this lesson. How the hook-up is made is crucial, so this lesson does a great job of explaining and illustrating technical information on sling angles, diameter ratios, sling-eye performance, hook attachments, details about choke hitches and two-part sling hook-ups. In addition, common rigging accessories such as below-the hook devices are introduced in this lesson.
- Lesson 5 covers rigging inspection and controls. Rigging and hoisting puts materials in precarious situations. If the lift is compromised, the result could be significant property damage, injury or death. Because of this, it's vital to be thorough and maintain constant vigilance when rigging and lifting. Video and graphics are used along with clear guidelines to help trainees identify wire rope, slings, hooks and shackles that must be removed from service.
