A snatch block is a type of pulley with a hinged or removable sideplate that allows it to be easily opened and closed. It is typically used in conjunction with a wire rope or chain to change the direction of a load or to increase the mechanical advantage of a lifting system.

Snatch blocks can be used in a variety of applications, including in cranes, hoists, and other lifting equipment. They are particularly useful in situations where it is not possible to attach the wire rope or chain directly to the load, or where the load needs to be lifted from a fixed point.

One advantage of snatch blocks is that they can be easily attached to a load or to a fixed point using a shackle or other connecting device. They are also relatively lightweight and easy to handle, making them a convenient tool for use in a variety of lifting applications.

It is important to use snatch blocks safely and correctly to avoid accidents and injuries. This includes selecting the appropriate size and type of snatch block for the specific application, inspecting the block for damage before use, and following proper lifting and handling techniques.
