This course is intended for those who have already participated and understand the fundamental concepts of a Qualified Rigger course and the hands-on applications executed during rigging inspections and operations. Persons attending this course will learn the formulas and calculation methods for job planning and load control, along with a strong understanding of crane dynamics and how they affect load stability. Learn how to correctly select hardware and slings to build a bridle, how to build a 4-leg sling hitch that properly carries the load, and how to use rigging tools that allow for load turning and leveling. It is imperative that all individuals who prepare, use, and work with or around hoisting and rigging equipment are well trained in both safety and operating procedures.
This program includes technical training, hands-on skills training, and the required examinations to meet OSHA standards. The course teaches the proper use and pre-use inspection of rigging gear, slings and below-the-hook lifting devices to ensure those who have completed the training are competent. Discusses lift plan implementation, including reference information, calculations, single- and multiple-crane lifting, critical lifts, and engineering considerations
The course also explains how load weight and center of gravity affect load balance along with stability during movement. Load calculations for multi-crane lifts are presented, along with the application of equalizer beams. The movement of loads up an inclined plane and the line pull required are examined in detail. The module concludes with guidance in the rigging and handling of rebar bundles.
The single most important precaution in hoisting and rigging is to determine the weight of the load before attempting to lift it. At the same time, riggers must also:
• Determine the available capacity of the equipment being used
• Rig the load so that it is stable and under control during the hoisting process
• Make allowances for any unknown factors.
In addition, riggers must be aware of common hazards, factors that reduce capacity, the inspection
and use of slings, and safe practices in rigging, lifting, and landing loads.
