Because most of the time the rigger in the field only has one connection point to collect their slings, it is important that they understand best practices for rigging triangles and angles formed.
The rigging triangle is formed any time two or more slings are connected to a load and the other end of the slings are collected in a common point such as a hook, shackle, or ring. Whether the slings are chain, wire rope, or synthetic rope, sling angle best practices are the same.
Sorting hooks are not your typical everyday hook for most companies, but for those companies and individuals who use them, and whether you call them lay out hooks, pelican hooks, shake out hooks, or sorting hooks, a little refresher on correct application may be in order.
The sorting hook was manufactured for the intended use for sorting and laying out plate, pipe, cylindrical shapes, and other items that allow engagement to the full depth of the hook throat in multiple sling leg applications.
We all have heard of rigging accidents, injuries, and even fatalities that may have been prevented if the rigging gear and/or slings had been properly inspected before the shift began or during its use. However, I still find individuals who are not aware of the need to perform an initial inspection.
In the world of rigging, many loads or machinery are fitted with weld-on permanent lifting points (pad eyes) that are used to connect to rigging hardware and slings. Often, the rigging hardware of choice to connect the sling to the pad eye is a Crosby shackle.
