Below-the-hook lifting tools are a critical component of any lift. Unfortunately, they are often overlooked during regular PM activities. Inspecting these devices on a regular basis is as important as inspecting your cranes. In fact, it's the law. ASME B30.20, as well as OSHA and other
state plans clearly define inspection requirements for all below-the-hook devices. Types of inspections are as follows:

- Initial Inspection - to verify compliance with construction requirements

- Frequent Inspection - based upon service, daily, weekly or monthly.

- Periodic Inspection - based upon service, annually minimum, with documentation.

Below-the-hook devices must also be clearly marked for tonnage and have a data plate installed by the manufacturer. All devices are required to be fabricated with a predetermined safety factor and all welding must conform to ANSI/AWS D1.1.

 

SLINGS AND BELOW THE HOOK DEVICE FAILURES ARE RESPONSIBLE FOR OVER 40% OF ALL OVERHEAD CRANE ACCIDENTS.
