Rigging is the process of lifting and moving objects. Slinging is the name for the materials used to connect the load to the crane or any other type of lifting device. Rigging and Slinging are operations that require a firm grasp on how to operate machinery and equipment safely. Often, the objects are odd sizes or extremely heavy. Those characteristics in themselves are part of the reason why the job requires specialized training.
Riggers
Riggers are workers who attach loads to and detach loads from cranes or other lifting devices.. A rigger can be qualified to do one specific type of rigging but might not necessarily be qualified to do other types of rigging jobs.
Safe Work Around Rigging
Precautions should be taken when working around cranes:
- All employees must wear hard hats when working around cranes actively being used for rigging
- All employees must maintain a safe distance from cranes that are moving loads
- Never move loads over employees or allow employees to walk under lifted loads
- Never leave a suspended load unattended or allow employees to walk under a load
- If a crane breaks down mid-load, secure the load in place or block the area
- An operator should stay at the controls, or lock out and tag controls until the crane is repaired
Slings
Slings are simple machines and useful devices for making things happen around high-risk job sites, and they are frequently employed for certain tasks with utility and electrical work.
To prevent potential accidents due to damaged equipment, slings must be inspected each day before use by a competent person designated by the employer. The sling and all fastenings and attachments must be inspected for damage or defects. Additional inspections must be performed during sling use, where service conditions warrant.
Safe Practices for Utility & Electrical Personnel
- Do not use damaged or defective slings.
- Do not use non-approved, makeshift slings.
- Do not shorten slings with knots, bolts or other makeshift devices.
- Make certain that sling legs are not kinked.
- Never exceed the sling’s rated capacity, or working load limit.
- Securely attach the sling to its load.
- Never place your hands or fingers between the sling and its load while the sling is being tightened around the load.
- Protect the sling from cuts and abrasions by padding sharp corners.
- Keep all employees clear of loads about to be lifted or suspended.
