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.

When is a 'qualified' rigger required per the new OSHA CDAC standard?

A qualified rigger is required during the assembly/disassembly of cranes, and when employees are engaged in hooking, unhooking or guiding the load, or in initial connection of a load to a component or structure and are within the fall zone.

Definition of ‘fall zone’– the area (including but not limited to the area directly beneath the load) in which it is reasonably foreseeable that partially or completely suspended materials could fall in the event of an accident.

    Special Note: Classroom training as provided by Crosby is only one element in becoming a qualified, competent, or certified rigger. Crosby strongly encourages that seminar attendees also obtain “hands on” training and appropriate on the job experience as well.

What is required to become a certified rigger?

Normally one must pass a written and a practical hands-on exam. The organizations below administer or offer rigger certification:
NCCCO – National Commission for the Certification of Crane Operators –
NCCER – National Center for Construction Education and Research –
Contact ACRP (Association of Crane and Rigging Professionals) – for other possible sources of testing
Note:  Some cities, states or employers may have special requirements.

Does Crosby have a form to assist end users in proving that a rigger is 'qualified' in their employment?

Yes. Please download the Qualified Rigger Management Sign-Off Authorization Form below:
Crosby’s Qualified Rigger Management Sign Off Authorization Form

Does attendance at a Crosby rigging seminar make the attendee a certified rigger?

No. Crosby does not certify riggers. Certification normally requires passing a written and hands on practical exam administered by a third party. Crosby however does provide educational seminars that greatly help individuals in their endeavors to become a competent or qualified rigger. 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. To request an onsite 4- or 8-hour Crosby seminar, please visit the Training section of the website.  Proper paperwork must be submitted and reviewed by Crosby before training can be confirmed.

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.
