![]() ![]() There are a variety of factors to keep in mind when choosing a block for your rigging needs:Ĭheck the Working Load Limit (WLL) of both the snatch block / wire rope pulley and the wire rope. With so many different variations, sizes and weight limitations, it's important to know what to look for. Unless you specifically need a block that opens, these products can generally be used interchangeably, and the option that's right for you usually comes down to user preference. The difference is simple: a snatch block comes with a metal plate that is designed to open, allowing for easy threading of your wire rope or cable.Ī pulley, on the other hand, stays closed during the reeving process. While many use "snatch block pulley" to refer to both, this term is actually a combination of two distinct pieces of equipment. ![]() What's the Difference Between a Snatch Block and a Wire Rope Pulley? W e offer snatch blocks and pulleys in various designs and sizes, including stainless steel blocks, square blocks, single and double pulleys, swivel blocks, and more, along with the compatible wire rope. This cuts the direct pull load in half, which doubles the amount of weight your winch can pull. 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. Also called a rigging block because it contributes to or "snatches" the mechanical force of pull, it offers a unique combination of power and flexibility. Snatch & Pulley Block Riggingįor use with everything from sailboats to ATVs, these can be a real workhorse. The force required diminishes proportionately with the amount of pulleys or "loops" used during the hoist. Their design offsets the anchor point and changes the direction of the rope / line, redistributing the weight of your load.Ĭommonly utilized in pulley block and tackle systems, snatch blocks or cable pulleys are used in conjunction with wire rope or cables by looping the rope through the pulley (around the sheave) several times before hooking to the load. Snatch blocks and wire rope pulleys are common lifting mechanisms used for rigging and lifting applications. These versatile tools reduce the amount of force required to move or lift heavy objects.
