Snatch Block/Hoisting block and tackle/Lifting Block/Hoist Tackle/Swivel block--Wu Zhou power tools
A snatch block is essentially a pulley inside a metal casing that is meant to help with winching duties.
Snatch swivel block is a wheel with a grooved edge to hold the rope or cable, combined with an axle or pin, side plates and a means of attaching it to something, typically a hook or shackle. Blocks are used in "block & tackle" combinations using multiple sheaves and two block assemblies, to increase mechanical advantage.
Snatch lifting block is a specially-designed block which is used to "snatch" loads or anchors, and is designed so that the side plate can be opened or swung away for the easy insertion of a loop of rope or cable without having to thread a bitter end through the side plates, and can thus be inserted anywhere in the cable without having to remove the load first to change the direction of the cable pull.
