Top Swivel

Overhaul Balls for Cranes

OverhaulBalls Top Swivel 041 TOP-SWIVEL-OHB-2-Model[1]

The advantage of the top swivel overhaul ball lies in the ability of its upper fitting and attached wire rope to move independent of its ball and lower fitting. Gunnebo Johnson Corporation introduced its first top swivel balls in 1966 in response to requests for units with more accessible upper fittings. From these have evolved the broad line of precision assemblies which this company now manufactures. In all, our offering consists of some 138 models with weights ranging from 37 through 1,478 pounds; capacities, from 3-3/4 through 30 tons. The J-Latch is now standard.
