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
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.

Crane Institute Certification (CIC), recently announced that the mobile crane operator designation, Friction Crane, will be available in 2014. A friction crane is a lattice boom crane that uses clutches and foot brakes for load control instead of a hydraulic system as with modern lattice boom cranes. Friction cranes are no longer manufactured; however, many are still in use on job sites. Since these cranes are still in service and their operation is completely different than their modern counterpart, it is important for accrediting agencies to test operator skills on the crane types they are expected to operate.
