When it comes to lifting or pulling heavy loads with wire rope, using the right snatch block pulley can significantly increase your system’s efficiency and capacity. However, not every snatch block or pulley block setup is suitable for every project. Before selecting equipment, it’s important to understand the differences between block types and their specific applications.
Here’s a breakdown of the snatch blocks available for rent through LGH, including details that can help you choose the best option for your next job.
• Drop-forged, heat-treated swivel hook or swivel shackle

Whenever lifting blocks, winch snatch blocks, or any rope-based sheave pulley system is used, keep in mind that the load on the supporting structure increases—not just from the weight of the load itself, but also from the hoisting effort. It’s critical to confirm that your structure, rigging points, and all hardware can handle the increased load imposed by these systems.
Always inspect the integrity of your connection points and ensure all gear used in conjunction with pulley blocks meets the necessary capacity and safety requirements.
