Top Swivel Type 4


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.

Gunnebo Johnson- began in the 1930’s in the oilfield tool manufacturing business. A line of wellheads bearing the famous Hinderliter name was developed, followed by the introduction of Johnson crane blocks. These lines were expanded with the addition of overhaul balls, wedge sockets, swivels, specialty blocks and, of course, a complete line of snatch blocks and sheaves, heavily used in the oil field.

Today, Gunnebo Johnson is a modern part of centuries old Gunnebo Industries of Sweden, with a perfect blending of above and below the hook products for industrial lifting and material handling.

Johnson blocks and overhaul balls dominate the North American lifting Industry. Johnson snatch blocks, specialty tackle and ForgeFab® sheaves are found wherever experienced people insist on the best and most reliable products in the toughest applications.

From specialty swivels deep in the ocean, to blocks and sheaves in the Gulf of Mexico and the harsh North Sea, Johnson products are at work everyday around the globe. Johnson products give you quality performance and value unmatched in the industry.
