Safety precautions using safety engineered swivel hoist rings
Read and follow the Safety Precautions listed below.
1.
Meters must only be lifted by personnel properly trained in the safe practices of
rigging and lifting.
2.
Remove the plug bolts installed in the tapped holes on the top of the flanges. Do not
discard the bolts as they must be reinstalled once the lifting operation is complete
to prevent corrosion of the tapped holes.
3.
Make sure the tapped holes on the meter are clean and free of debris before
installing the hoist rings.
4.
Use only the safety engineered swivel hoist rings that are rated for lifting the meter.
Do not use any other type of hoist rings with the same screw size or heavy duty hoist
rings. The meter tapping and counter bore size are suitable only for the hoist rings
specified by Daniel.
5.
When installing a hoist ring, make sure the base surface of the hoist ring fully
contacts the machined flat surface of the tapped hole. If the two surfaces do not
come in contact then the hoist ring will not hold its full rated load. Torque the hoist
ring attachment bolts to the limit indicated on the hoist rings.
6.
After installation of the hoist rings, always check that the ring rotates and pivots
freely in all directions.
7.
NEVER attempt to lift the meter using only one hoist ring.
8.
Always use separate slings to each hoist ring. NEVER reeve one sling through both
hoist rings. The slings must be of equal length. Each sling must have a load rating
that equals or exceeds the hoist ring load rating. The angle between the two slings
going to the hoist rings must never exceed 90 degrees or the load rating of the hoist
rings will be exceeded.
