provides the weight of the device itself—which must be considered when calculating if the load is within the capacity of the crane being used for the lift. It also provides the manufacturer’s name, contact information, and unique serial number. If you were to have issues with the device down the road, you would need that information for traceability purposes. ASME tag requirements also provide the end-user with information regarding how and why the product was designed. Design Category tells whether the lifter was designed for a specific application or designed to be a general purpose lifter. Service Class provides a service classification for the device by factoring in load cycles per day, as well as the desired service life (in years) of the device.
Always make sure that your below-the-hook lifter has the capacity visible, as well as a plate or tag that is welded or stamped into the device. Lifting beams and other devices can get smashed and abused during the course of their lifetime and a rickety plate can get knocked loose, or a painted marking can get marred or scuffed and become illegible. If an inspector finds a below-the-hook lifter that’s missing any or all of this information, they’ll have to fail the device for meeting compliance requirements— and you could be looking at an expensive and time- consuming process to get your device reverse engineered and re-tagged.
WRAPPING IT UP You shouldn’t look at the inspection of your lifting and rigging gear as a nuisance that’s going to disrupt production or as an added expense when you have to replace discarded rigging gear. Our goal for this article is only to open your eyes to the most common problems our rigging inspectors find when they’re out in the field. Share this article with your team and put a plan together to assess your lifting and rigging equipment and procedures. Education and transparency are key factors in any safe lifting and rigging environment. Your willingness to improve your processes confirms your commitment to job site safety and proves it’s a top priority within your company or department.
