FEATURES: These hoist rings have a center through-hole instead of a bolt, for mounting with a custom anchoring system. Heavy-duty forged alloy-steel ring pivots a full 180 degrees, but does not rotate (install so that lifting force is applied in the pivoting direction). Safety factor = 5:1. Black oxide finish is standard, with cadmium plating available as a special. Patent no. 4,570,987, 4,641,986, 5,405,210, and other patents pending. Made in USA.
SIZES: Available in the following load capacities and throughhole diameters — see Dimensions page for part numbers:| | 7000 Lbs | | | | 3/4" diameter | | | 10000 Lbs | | | | 1" diameter | | | 15000 Lbs | | | | 1-1/4" diameter | | | 24000 Lbs | | | | 1-1/2" diameter |
INSTALLATION: Rated load capacity is based on using a bolt or stud with 180,000 psi ultimate tensile strength. If a bolt with lower strength is used, or if the workpiece anchor material is incapable of supporting the weight, then rated load capacity must be reduced accordingly. Since these hoist rings do not rotate, install so that lifting force is applied in the pivoting direction.
SAFETY PRECAUTIONS: See Hoist Ring Safety Precautions at the beginning of this catalog section.
MATERIAL: Alloy steel, heat treated, black oxide finish (cadmium plating available as a special). 100% magnaflux inspected. RoHS compliant. |
