Our Snatch blocks are frequently used in offshore applications and often utilised to increase the capacity or divert the direction of a wire rope. Snatch blocks are designed and manufactured with high working load limits to ensure they can effectively handle the extreme loads that winch recoveries can place on your recovery gear. Snatch blocks are used as a pulley point in vehicle-based winch recoveries to redirect the course of a winch line or to lessen the load placed on the winch during the recovery. Stainless Steel Blocks, Sheaves & PulleysĪ snatch block is a pulley that ’s covered by a clever metal case and it is used with winches to pull rope.Snatch Block with Shackle - Used in permanent and temporary rigging applications.Stainless Steel Blocks, Sheaves & Pulleys Snatch Block with Hook - Normally used with wire rope hoists and winches during temporary applications. Types of snatch block available on FAD Equipment Store This includes the anchor point itself if the anchor point isn’t secure or can’t handle the pressure, this too could result in disaster. With so much force resting on the snatch block, it’s imperative that the equipment is set up correctly and all components attached securely. If the load becomes too high and the block (or other rigging) fails, the resulting slingshot effect can be catastrophic. In fact, the pressure on the wire rope can be as much as twice that of the actual load being towed or moored. When used in conjunction with a winch, a huge amount of force passes through the snatch block. Snatch blocks can be dangerous if used incorrectly, so it’s important to know what you’re doing. In other applications the purchase block will be rigged to a fixed point and the item being moved or lifted will travel independently. This is where the block is attached to the load being moved it moves with the load. When rigged into a system, a snatch block can be arranged as a running block (also known as a traveling block). To give mechanical advantage when lifting a load, such as a motor, or a multiplier block arrangement.To re-direct line path from a winch system or improve its pulling capacity by up to 100%.Arborists use the tool to assist with lowering, lifting or dragging cut tree limbs.Vehicle recovery used with 4x4 first responders.As a load multiplier on a marine mooring system allowing for greater pulling power but also control.With gin poles in cell tower or tower crane erection.A pulley block is typically closed and any wire rope rigged into the system will have to be reeved. They are primarily designed for lifting, slewing or slewing heavy goods when working as a pulley point that can redirect the course of a winch line.Īs the snatch block’s name implies, the operator may open the side plates of the block, allowing the block to be easily inserted anywhere along the length of the wire rope, even if it is terminated at both ends. Some snatch blocks also offer grease zerks to help maintain the bearings, enabling long life and friction-free use. It is important to look at the loads, line speed and duty cycles of work before deciding on sheave bearing options. Typically, the sheave will run on either brass bushes or roller bearings. Multi sheave models – used to give mechanical advantageĪ snatch block is a heavy-duty sheave or pulley inside a forged steel casing.
