Why "snatch" blocks?
The snatch block is one of today's most widely used types of blocks. As generally applied, its title refers to that group of intermittent-service blocks which quickly attaches and "snatches" or moves loads over comparatively short distances. This as opposed to long lifts and continuous service for which crane and construction blocks are designed.
