Eyebolts can make a rigging job easier, but easier doesn’t mean safer.
An untrained rigger may incorrectly believe he can connect to an eyebolt by any means that work, but it is never that simple.
Eyebolts like all rigging gear, have requirements for safe use. Always follow manufacturer procedures when available, and remember these safety tips.
- When used for lifting, eyebolts must be made from forged alloy steel, not cast iron
- To connect to a load, eyebolts must be strong enough to withstand forces applied
- The shoulder of an eyebolt must be flush with mounting surface
- Shouldered eyebolts must be used when pulling at an angle
- Angular pull must be in the plane of the eye
- Eyebolts must have sufficient capacity; greatest when loaded in the vertical and reduced if pulled at an angle
August 5, 2014 (Sanford, Fla.)—Crane Institute of America announces the availability of the newest edition of the industry’s favorite rigging handbook. Rigging, by James Headley, has been converted from imperial to metric. Providing practical information and great illustrations, the Rigging Metric handbook contains the latest information on wire rope, rigging hardware, and slings, including capacity tables and charts.
“For years, the handbook Rigging has been popular outside the United States for use in training,” said Jim Headley, President of Crane Institute of America. “Customers in Canada, South America, Europe, Australia, and the Middle East have been asking for a metric version of the book.”
Along with the rated capacity tables of slings and rigging hardware, the book covers how to calculate load weight, how to calculate sling loading, and proper load handling techniques. The information is applicable to rigging operations no matter where you are in the world. By offering two versions of the books, trainers and students now have a resource that improves communication, understanding, and safety.
The book can be ordered at Crane Institute’s Online Store and costs $19.95 USD.

Killed – two workers in California when their personnel basket fell nearly 80 feet.
OSHA has strict requirements regarding hoisting personnel. If these requirements are followed, such accidents should cease to happen. The actual cause of this particular accident is still unknown to the public as the OSHA report will take time to surface. Early speculation is that the hook failed or the basket came off the hook.
Hooks used in personnel hoisting operations “must be capable of supporting, without failure, at least five times the maximum intended load applied” according to OSHA 29 CFR 1926.1431(g)(3). In simple terms the hook will withstand a 500% overload before it will fail at which point it will bend, not break. On a crane as large as the one used in the operation, the weight of the heaviest personnel basket and its contents should not come close to the yield point of the hook.
This begs the other question, how could the master link for the bridle supporting the basket come off the hook?
OSHA requires hooks used for hoisting personnel “must be of a type that can be closed and locked” (1926.1431(g)(1)(i)(A)). Closing the hook’s throat would prevent the basket from coming off the hook. Now let’s assume the hook was not equipped with a latch or the latch was defective.
- The weight of the basket should keep the master link in place in the bowl of the hook.
- For the basket to come off, an upward force would have to be placed on the master link. This could cause the master link to slip over the hook tip.
- An upward force could be generated by hitting an object with the personnel basket.

Crane Institute Announces Plans for New Programs
August 4, 2014 (Sanford, Fla.) — More than 15 Training Specialists for Crane Institute of America recently met at Crane Institute’s headquarters for Annual In-Service Training in order to provide the best possible customer experience. All Training Specialists are certified and qualified through Crane Institute of America. The training session includes refreshers on the latest equipment and changes to regulations.
The training meeting included a conference call with Crane Institute Certification’s (CIC) Executive Director, Debbie Dickinson, to learn more about OSHA’s proposed delay of crane operator certification requirements. CIC submitted viable solutions to OSHA with the intent to satisfy the agency’s concerns over employer responsibility to qualify workers. Subsequently, an industry coalition, including CIC, was formed to represent the interests of the crane industry.
In other news, Dickinson reported three states have or will adopt language requiring certification or licensing by crane type and size. These include California, Washington, and New York. Finally, she announced the launch of two new CIC certifications; Service Mechanics Truck and Lift Director.
New Programs and Resources
Crane Institute of America announced to its Training Specialists new programs currently in development. Two new training courses for people involved in crane management are set to be released in Fall 2014. The new Lift Director and Lift Planner courses are designed to prepare students for the CIC Lift Director Certification Exams. In addition, look for a course for Assembly/Disassembly Director in 2015.
Also new is a metric version of the handbook, Rigging, available for purchase on Crane Institute’s online store this September.
Crane Institute now has a public LinkedIn group, called Crane and Rigging, for those in the industry with related questions. Crane Institute Training Specialists offer a credible source...
When synthetic round slings were introduced, the big concern was how to determine if fibers, hidden by the protective jacket, were broken.
At first, many companies and government agencies banned them because the fibers could not be inspected. However, the jacket around the sling has always been made to fit loose. When it became tight or load baring, most likely internal fibers had broken.
Because of the continued resistance of buyers, manufacturers began installing external indicators of fiber failure. One method uses a large fiber that sticks out through the jacket seam. When the fiber isn’t visible, it indicates that too many fibers have broken. Another method is to include a fiber optic thread among the fibers. If a light beam cannot be seen through the fiber, it indicates that the fiber optic cord as well as other fibers have broken.
Our Rigging Equipment Inspector training program includes inspection of synthetic rope slings.
