Double-Sheave Swivel Pulley Block
This heavy-duty Dual-Sheave Block is the primary component for establishing powerful mechanical advantage in critical lifting and pulling operations. It is designed to sustain high loads and continuous stress while maintaining safe, stable cable management.
- Product Introduction
Structural Integrity & Serviceability
Articulated Load Point: The connection features a forged, load-rated hook mounted on a sealed bearing turntable. This rotational mechanism automatically corrects cable torque, preventing line kinking and ensuring the block maintains perfect alignment with the load vector.
Unitized Housing: The pulley wheels are protected by a robust, fabricated steel cage. This monolithic structure is welded for maximum rigidity, defending against external impact and housing distortion.
Maintenance Design: The central wheel pin is engineered for full access, allowing simple lubrication and replacement of internal bearing elements to ensure maximum operational lifespan.
Twin-Groove System: The assembly contains two parallel rope channels, optimizing leverage and ensuring the load is equally distributed between the separate lines.
Specifications & Compliance
We manufacture every block to meet stringent industrial safety and performance standards.
Leverage Boosting: Optimized for use in force multiplication setups, readily adapting to 3-part, 4-part, and similar reeving plans.
Certified Materials: The structural framework uses high-grade fabricated metal, complemented by a forged alloy suspension hook equipped with a mandatory safety latch.
Rated Tonnage: Each block is permanently marked with its Certified Lifting Capacity (WLL) and is supplied with full material traceability.
To receive a tailored quotation, communicate your required Rated Tonnage and the size of the hoisting cable.
