Rigging is the equipment such as wire rope, turnbuckles, clevis, jacks used with cranes and other lifting equipment in material handling and structure relocation. Rigging systems commonly include shackles, master links and slings, and lifting bags in underwater lifting.
In the simplest possible terms, rigging is what attaches the load being lifted to the crane that’s lifting it. This sounds a lot easier than it actually is. In order to lift a load properly, the loads must be balanced and secure. Many loads are very heavy and strangely shaped. It’s important that they’re rigged in such a way that they don’t shift out of position while being lifted – even if the wind is blowing or conditions are less than ideal. The consequences of failure are extremely high: if a multi-ton load is ever dropped, property will be damaged, and people can get hurt.
Riggers use shackles, clamps, and other fasteners to attach loads to the chains, cables or straps that are connected to the crane. There’s a lot of engineering involved to make sure everything’s rigged properly.
Safety should be the first priority when performing lifting operations. An understanding of the capabilities and limitations of the equipment will support this. The safety policy “lf It‘s Not Safe, Don‘t Do It” is important not only for your safety, but
the safety of your coworkers.
