SNATCH BLOCK / PULLEY FAQ

A snatch block, also known as a pulley, is a mechanical device with a grooved wheel designed to change the direction of a rope or cable. It is commonly used in lifting and rigging applications to increase the line’s mechanical advantage.

While both snatch blocks and regular pulleys change the direction of a line, snatch blocks typically have a hinged side that allows the block to be opened and the rope or cable to be inserted without threading it through.

The primary purpose of a snatch block is to change the direction of a line and increase the mechanical advantage during lifting or pulling operations. It can also be used to redirect a line around obstacles.

Yes, snatch blocks are versatile and can be used for both vertical and horizontal lifts. The block’s design allows for flexibility in changing the direction of the load.

Consider factors such as the load capacity, rope diameter, and the specific requirements of your lifting or rigging operation. Choose a snatch block that meets or exceeds these specifications.

A single-sheave snatch block has one grooved wheel, while a double-sheave snatch block has two. Double-sheave blocks offer increased mechanical advantage and are often used for heavier loads.

The compatibility of a snatch block with a rope or cable depends on factors such as diameter and construction. Always use the type of rope or cable recommended by the block’s manufacturer.

Follow the manufacturer’s guidelines for rigging the snatch block. Ensure the rope is correctly seated in the sheave and properly secured. Use appropriate hardware for attachment.

Snatch blocks are generally designed for static or slowly moving loads. Using them for dynamic loads, such as sudden or rapid movements, may exceed their designed capabilities and pose a safety risk.

Perform regular visual inspections before each use and more thorough periodic inspections at intervals recommended by the manufacturer and relevant safety regulations.

Yes, snatch blocks are often used in combination with other lifting equipment to achieve specific rigging configurations and increase lifting efficiency.
