subject: Rigging Training: Suitable Tricks For Heavy Lifting [print this page] Carrying heavy objects in some industries may not be possible without the use of certain equipment, for which rigging training may be necessary. Safety and care are very important in the workplace, especially if the job involves lifting and transporting large and heavy items. People who are involved in such jobs need proper instruction and practice before they gain access to lifting equipment and materials. Untrained workers may endanger themselves and the people around them, and risk damaging costly machinery or the objects they are lifting. That is why it is advisable to have your people undergo training. Here are a few tips that may help workers engaged in lifting objects.
Always Consider the Center of Gravity
The center of gravity of any object is that portion you assume to have the largest concentration of its entire weight. At rigging training, you will learn that lifting an item, especially a heavy one, requires understanding how to position it in a hoist so the center of gravity does not cause any problems. Use a hoist hook directly above the item's center of gravity. Placing your hook too far to one side may cause tilting, which is dangerous. The unequal stress on the legs of the sling may cause the rope to snap, or the lifting apparatus to sway to one side and hit something or somebody. Quickly stop the lifting if you notice any tilting, and rearrange your load so the center of gravity is directly below the hoist hook.
Use More Sling Legs with a Bigger Angle with the Horizontal
Rigging inspection may penalize you if the inspectors find out you are using too few sling legs for heavy lifting. A small angle with the horizontal means the legs are under a lot of strain. Having few legs and a small angle with the horizontal means you need more rope and slings. Avoid trying to cut down on the cost of rope by using too little of it. This can end up damaging the rope, the load, and the machinery, along with hurting people. Use more sling legs and a large horizontal angle to help the sling distribute the weight perfectly.
Do Not Exceed Load Capacities
Every sling has its own rated capacity, as any form of rigging training can probably teach your employees. A sling typically comes with information about its capacity when you get it from the supplier. Ask for this rating information from the seller if your sling does not come with it, or requests it directly from the manufacturer. The size, the material, and the type of hitch are usually part of the capacity rating. Never exceed the rated capacity of your sling or any other material or equipment as it can lead to accidents.
Know Your Material and Equipment
It is usually safer to use new material and equipment, as anybody who has gone through rigging inspection would know. Materials like slings, however, do age and lose their original capacity, so always know the history of your things. Follow the care instructions from the manufacturer to keep your stuff usable and safe for a long time. Submit your workplace for inspection periodically to make sure you are following the right standards and practices in the industry.
