Crosby® supplies round pin, screw pin and bolt-type shackles. What is the proper application of each?

Round Pin Shackles can be used in tie down, towing, suspension or lifting applications where the load is strictly applied in-line. Screw Pin Shackles can be used in any application where a round pin shackle is used. In addition, screw pin shackles can be used for applications involving side-loading circumstances. Reduced working load limits are required for side-loading applications. While in service, do not allow the screw pin to be rotated by a live line, such as a choker application. Bolt-Type Shackles can be used in any applications where round pin or screw pin shackles are used. In addition, they are recommended for permanent or long term installations and where the load may slide on the shackle pin causing the pin to rotate.

QUIC-CHECK® is Crosby’s patented system that incoporates markings forged into selected products which address two (2) QUIC-CHECK® features: Deformation Indicators: Two strategically placed marks, one just below the shank or eye and the other on the hook tip, which allows for a QUIC-CHECK® measurement to determine if the throat opening has changed, thus indicating abuse or overload. Angle Indicators: Indicates the maximum included angle which is allowed between two (2) sling legs in the hook. These indicators also provide the opportunity to approximate other included angles between two sling legs.

What is the definition of a “qualified rigger” per the OSHA (CDAC) standard?

The new OSHA standard says that a “qualified rigger” is someone who meets the definition of a qualified person. OSHA states that a “Qualified Person” is – a person who by possession of a recognized degree or certificate of professional standing, or who, by extensive knowledge, training and experience, has successfully demonstrated the ability to solve or resolve problems relating to the subject matter and work.

The time spent in our seminars and certificate of training received goes a long way in proving rigger qualifications when using Crosby rigging products in conjunction with slings. The education achieved can also prove useful in preparing for the written and practical exams to be a certified rigger. See information later in this memo on how to become a certified rigger.
