Swivel Toggle Eye Pulley Block Double Sheaves.
Unlike the single-sheave pulleys mentioned earlier, this specific model features two grooved wheels (sheaves) side-by-side inside a single housing.
Swivel toggle eye double sheave pulley blocks are heavy-duty rigging components designed to provide a 2-to-1 mechanical advantage while allowing full rotational and angular flexibility under load. The swivel toggle mechanism prevents line twisting and automatically adjusts to changing load angles, making them essential for marine, industrial, and hoisting applications.
Key Features
Double Sheave Design: Allows you to run two separate rope lines simultaneously or loop a single rope back and forth to create a block and tackle system, which cuts the effort needed to lift heavy loads in half.
Swivel Eye: The top attachment loop rotates a full 360 degrees. This automatically aligns the pulley with the direction of the load, preventing the rope or wire from twisting, binding, or kinking during use.
Stainless Steel Build: Typically manufactured from 304 or marine-grade 316 stainless steel to provide maximum rust and corrosion resistance in highly humid, outdoor, or salt-water environments
Available in 25mm, 32mm, and 50mm sizes, each unit is inspected for dimensional accuracy and load performance. The product is compatible with a wide range of ropes, chains, or cables, offering dependable support for both static and dynamic load systems.
Key Purchase Considerations
Material: Opt for T316 or T304 Stainless Steel for saltwater/marine applications to prevent rust. Choose Galvanized Clear Zinc Steel for cost-effective indoor or dry outdoor industrial settings.
Rope Capacity & Sheave Diameter: Match your exact wire or fibrous rope diameter to the sheave groove to avoid premature rope wear or binding.
Working Load Limit (WLL): Always ensure the rated WLL exceeds your maximum expected lifting weight.
