Pulley Block / Snatch Block
Yulong pulley blocks (also called snatch blocks or sheave blocks) are essential components in wire rope rigging systems. They change the direction of a wire rope, provide mechanical advantage in lifting systems, and enable complex reeving configurations. Available in single-sheave, double-sheave, and multiple-sheave configurations with either cast iron or steel pulleys to suit different load and environmental requirements.
- Ductile iron or steel sheaves with precision-machined rope grooves
- Sealed ball bearings or bronze bushings for smooth rotation
- Forged steel shackles and swivel hooks with safety latches
- Snatch block design with hinged side plate for easy rope installation
- Galvanized or painted finish for corrosion resistance
- High safety factor (4:1 for lifting, 5:1 for personnel applications)
