Snatch Blocks & Wire Rope Pulleys
snatch blocks and pulleys banner
Snatch blocks and wire rope pulleys are common lifting mechanisms used for rigging. Using a snatch block in a block and tackle application reduces the amount of force required to lift an abnormally heavy object. A pulley system is used in conjunction with wire rope or other types of rigging ropes, by looping the rope through the pulley (around the sheave) several times before hooking to the object. The force required diminishes proportionately with the amount of pulleys or "loops" used during the hoist.

We offer a large variety of rigging equipment that"s in stock and ready to ship. Our selection of rigging blocks and pulleys includes snatch blocks, wire rope blocks, wire rope pulleys, and more.

A wire rope pulley is a block that can be opened on one side to quickly and easily insert a wire rope without having to remove the load or change direction of the cable.

For use with everything from sailboats to ATVs, a snatch block can be a real workhorse. Called a rigging block because it contributes to or "snatches" the mechanical force of pull, it offers a unique combination of power and flexibility. When used with a winch, a block lets you pull or lift heavy objects by "breaking" the pull span between the object and the winch. This cuts the direct pull load in half, which doubles the amount of weight your winch can pull.

With so many different variations, sizes and weight limitations, it"s important to know what to look for when choosing a snatch block for the job. Factors to keep in mind when choosing a snatch block for your rigging needs:
  • Check the Working Load Limit (WLL) of both the snatch block and the wire rope. If the WLL of the pulley is not compatible with the WLL of the rope, it can create a dangerous situation if either one should fail.
  • Coordinate the size of the sheave in the snatch block to the diameter of the wire rope. If the wire rope is too large for the sheave, the block can crack. Generally, the wire rope-to-sheave size ratio should be 12:1 in order to hold the wire properly while under load.
  • Know your numbers. Because a snatchblock can cut the direct pull load in half, choose a rigging pulley that has a rating of double the pull of the winch you"ll be using with it.
We carry a variety of styles of heavy duty snatch blocks / wire cable pulleys; check the specifications for each product for break strength and load limits. We also carry a wide selection of wire rope in various sizes.

Along with heavy duty snatch blocks, we also offer smaller rigging snatch blocks and pulleys in various designs and sizes, including stainless steel snatch blocks, square blocks, single and double pulleys, swivel block, and more.

Choosing the right block and all the equipment to go along with it can be confusing. If you have any questions about using snatch blocks, choosing wire rope blocks, working load limits, etc., contact one of our sales specialists . They can help you find just what you need to get the job done safely.
