Tie Shou heavy-duty pulley blocks (also known as snatch blocks or lifting sheaves) are engineered for high-capacity crane hoisting, rigging, and directional line pulling in rugged industrial environments. Manufactured with high-tensile drop-forged alloy steel, hardened sheaves, and heavy-duty roller bearings, these pulley blocks offer working load limits (WLL) ranging from 0.5 Ton (1,100 lbs) up to 50 Tons (110,000 lbs) with a minimum 4:1 safety design factor.

• Versatile Sheave Configurations: Available in single, double, triple, and quad sheave arrangements to multiply mechanical lifting advantage.
• 360° Swivel Hook & Shackle Options: Drop-forged swivel hooks with spring latches or heavy-duty bow shackles prevent wire rope twisting under load.
• Quick-Opening Side Latch: Allows rapid insertion of wire rope without disassembling end fittings or removing anchor connections.
• Precision-Machined Sheave Grooves: Hardened rope grooves prevent wire pinch, reducing cable wear and prolonging service life.
