As we continue to pioneer the advancement of industry best practices below-the-hook, Danny Bishop reiterates the importance of pre-use inspection.
Most riggers are aware of the need to inspect their slings and rigging hardware every day, before and during their use, which is sometimes called the in-service or frequent inspection. And riggers are normally aware of the need for a thorough inspection, which is sometimes called the periodic inspection, that is required by many standards a minimum of once per year.
However, there is a critical inspection that is often overlooked or ignored by many companies in the various material handling industries, called the initial inspection.
Have you ever needed to determine the sling length for a desired angle of loading (horizontal sling angle), but perhaps struggled with how to get the correct answer?
How many times on the job site have you seen the riggers place more than two slings into one single point hook with no regard to the fact they may be tip loading, back loading, or even side loading the hook?
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.
