Snatch Block Hook Type
- A Snatch Block Hook Type is a mechanical device used to redirect the line of pull, making it easier to apply force in a desired direction.
- It consists of a grooved wheel (sheave) mounted in a frame, with a hook for attachment.

Functions
- Off-Road Recovery: Used to extract vehicles from mud, snow, or other difficult terrain.
- Construction: Employed for lifting heavy loads, such as beams and structural components.
- Tree Care: Used to tension cables and lift heavy branches.
- Marine Applications: Utilized for mooring boats, pulling anchors, and other marine tasks.
- Industrial Settings: Employed in various industrial applications, such as manufacturing and material handling.
Key Features
- Changing Direction: Snatch blocks are primarily used to redirect the line of pull, making it easier to apply force in a desired direction.
- Mechanical Advantage: By redirecting the line, a snatch block can effectively increase the mechanical advantage, allowing you to lift heavier loads with less effort.
- Reducing Friction: The sheave within the snatch block reduces friction, making the pulling or lifting process more efficient.
