For angular lifts, adjust working load as shown above. Check seating after applying an angular lift since the initial lift may cause the bolt to back away from the load. Angular lifts significantly reduce rated capacities. A regular nut eye bolt, also known as a plain pattern eye bolt, should not be used when applying angular loads as this procedure can bend or break them. This design means that these eye bolts can be used for angular loads of up to 45° SHOULDERED EYEBOLT Eyebolts have been around for over 100 years and have been doing a good job when used properly. Angular lifting should be avoided. 2. We understand that there are many factors that go into choosing the correct sling, wire rope, rigging hardware or lifting device for a lift! Drill and tap the load to the correct sizes to a minimum depth of one-half the eye bolt size beyond the shank length of the machinery eye bolt. Eye bolt identification markings: Shoulder Nut Eye Bolt โ€“ Installation for In-Line and Angular Loading: A.The threaded shank must protrude through the load sufficiently to allow full engagement of the nut. Shoulder eye bolt is manufactured in heavy duty forged steel and galvanized for corrosion resistance. SHOULDERED EYEBOLT Eyebolts have been around for over 100 years and have been doing a good job when used properly. They are not designed for side or angular loading. Always countersink receiving hole or use washer with sufficient I.D. It is very important that riggers understand this phenomenon completely in order to choose the proper eye bolt to make their lift safely. As the sling angle becomes smaller the tension being placed on the eye bolt increases while the eye bolts capacity diminishes drastically. Shoulder Provides A More Stable Base Of The Eye And Is Recommended For Angular Loading Applications Up To 45 Degrees; If Using For Angular Lifting, The Safe Working Load Is 25% Of Listed Limit ... (4 Pack) 3/4 x 2 Machine Shouldered Eye Bolts, Self Colored - U-Turn 4.2 out of 5 stars 21. Never use regular nut eye bolts for angular lifts. Angular lifts significantly reduce rated capacities. Buy them here at Rigging Canada. Loading at an angle will significantly reduce a boltโ€™s rated capacity. Loads should always be applied to eye bolts in the plane of the eye, not at an angle to this plane. This design means that these eye bolts can be used for angular loads of up to 45° If an eye bolt is not the proper rigging hardware for the lift, there are two main alternatives to using eye bolts as your attachment points. result from the angular loading. The manufacturer/importer must carry out the chemical analysis and the mechanical tests (or possess the relevant certification) on the type of steel used for each lot. INTRODUCTION The eye bolt hook is a very critical feature used to lift the load using a chain or seam. โ€ข When using lifting slings of two or more legs, make sure the loads in the legs are calculated using the angle from the vertical sling angle to the leg and properly size the shoulder nut or machinery eye bolt for the angular load. • Always be sure threads on shank and receiving holes are clean. The result of these tests must not be lower than 6 times the working load limit (WLL) marked on the lifting eye bolts and lifting eye nuts. shouldered. For instance, if hooks are being attached to the eye bolts, you need to make sure that the hook fits comfortably through the eye. After the loads on the eye bolts have been calculated, select the proper size eye bolt for the job. You will want to look at the drawings or consult with an engineer to make sure that the load can be safely lifted with the number of pick points you are planning to use and their locations on the load. Metric Shoulder Machine Eye Bolts are made from high strength steel and are suitable for use with angular loads. Shouldered bolt. Slings shall not be reeved through an eye bolt or reeved through a pair of eye bolts. select the proper size eye bolt for the job.
