Steel Wire Rope Bulldog Grips Clamps

Wire rope (or ‘bulldog’) grips are only suitable for permanent fixed stays or guys.

They can be one of the most dangerous fittings used by riggers if not used correctly. If the bolts are overtightened the rope will be crushed or if the bolts are under tightened slipping will occur.

At least three wire rope grips should be used, with the saddles on the live part of the rope, and the U-bolt pressing on the less heavily loaded tail of the rope. They should be spaced at least six rope diameters apart.

Do not use them on temporary stays or guys that have to be shifted and re-fastened because the the severe crushing and punishing action of the U-bolt. Do not use sections that are damaged by the clip and then straightened out to take the load.

Do not use bulldog grips on any load hoisting ropes. When connecting a lizard to a stay or guy, make sure that the crowns of the U-bolts press upon the lizard. Although they will (be) damaged, they are easily replaced.

Correctly applied bulldog grips may form an eye with 80 per cent of the breaking strength of the rope. If not correctly applied, they have no reasonable safe value.

Do not use a grip that is the wrong size or that has been strained or damaged. eg. use 3mm bulldog grip for 3mm wire etc Do not use a bulldog grip to directly connect two straight lengths of rope. If this is necessary, join two thimbles and then use the grips to make two thimble eyes.
