hoist ring allowing the hoist ring to reach its full 5:1 safety factor. • The hoist ring is free to swivel and pivot in every direction. o If the hoist ring binds up in any direction, it should be removed from service. • There are no signs of corrosion.
DME swiveling hoist rings are designed and rated to be pulled at any angle at the rated load. However, the applied load on a multipoint lift will increase if the sling angle is less than 90°.
Traditional Center Pull and Side Pull hoist ring assemblies are pull-tested and certified to 200% of rated load capacity and stamped with identifying date code. All hoist rings are designed for 5:1 strength factor.
Use Instructions. The load rating on each hoist ring is not simply total weight divided by the number of hoist rings. The resultant force can be significantly greater at shallow lift angles and with unevenly distributed loads. Determine the maximum load at any given lift angle by using this formula:
• Loads may slip or fall if proper Hoist Ring assembly and lifting procedures are not followed. • A falling load may cause serious injury or death. • Install hoist ring bolt to torque requirements listed in tables. • The side pull hoist ring frame will be only one part of a lifting system with several components
Do you know the correct way to install a hoist ring? A swivel hoist ring has torque specifications that provide the end-user with the proper tightness required for installation...
The force on each hoist ring is not just the total weight divided by the number of hoist rings. The force will be greater at lower lift angles. Make sure load is evenly distributed. See below. Formula with example data: F = W N Sin A CORRECT F = Force on each hoist ring W = Total weight = 4000 lbs. N = Number of hoist rings = 4 A = Lifting angle
