Dos & Donts

 

Hoist Ring Dos

  • DO observe working load limitations (be especially careful with eyebolts used for angle lifts—see sling angle chart below).

  • DO visually inspect hoist ring prior to use.

  • DO fully tighten hoist ring to recommended torque. Full thread engagement is required (no space between swivel bushing and lift).

  • DO assure proper thread depth—do not shim.

  • DO make sure hoist rings have free travel—they must swivel and pivot without restrictions.

  • DO insure sufficient thread depth in soft materials.  For example, in aluminum, the minimum effective thread engagement should be two times the diameter of the thread.

Hoist Ring Dont's

  • DON'T pull from side (center pull).

  • DON'T use oversize hook

  • DON'T use excessive sling angle Full thread engagement is required (no space between swivel bushing and lift).

  • DON'T steam clean or degrease

  • DON'T alter assembly

  • DON'T apply shock loads

  • DON'T allow side of ring contact with lift

  • DON'T alter Hoist Rings or use homemade lifting hardware

Engineering Recommendations
Jergens recommends the use of swiveling and pivoting hoist rings, rather than conventional eye bolts.
Before you begin, ask yourself:

1. Are you using the proper hoist ring for the application?

2. Is the hoist ring free to swivel and pivot? Are there any movement restrictions?

3. Are lifting hole(s) in the proper location

4. Do you have the correct hole size for the hardware – safe lift capacity?

5. Are the holes tapped deep enough to assure full thread engagement?
-Recommended hole depth for steel: 1.5xbolt diameter
-Recommended hole depth for aluminum: 2xbolt diameter

 


 

Applied Load Changes with Sling Angle
Jergens 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 degrees. So be sure to consider the sling angle when selecting lifting equipment. See illustration below.
