Gunnebo Johnson Snatch Blocks
Over 235 models of single and double sheave snatch blocks are offered. Capacities range from 2 to 30 metric tons; sheave diameters, from 3 through 24 inches. Custom designs and sizes available also.
This is true even on our heavy-duty top dead-end models, and makes it easy to reeve the block without removing any fittings from the end of the wire rope. Other features include choice of swivel hook, shackle, or tailboard blocks, which have no fittings at all.
Note that a snatch block’s wire rope-to-sheave diameter ratio is not the same as that recommended for crane and construction blocks. Since the height and frequency of the lift is not as much of a factor, larger sheaves are not as crucial to snatch block operations. However, provisions should be made to increase sheave size where the situation demands. Naturally a large sheave is an advantage insofar as bearing life and wire rope life are concerned.
Note also that the lower fittings on snatch blocks 2 through 20tons are not equipped with thrust bearings. They will not swivel as well under load.
