40 Ton Multi-Sheave Hook Block

The 40 Ton Hook Block Assembly is designed for heavy-duty double girder overhead crane systems.

Featuring a three-sheave configuration, this hook block ensures optimized wire rope distribution, reduced rope tension, and stable lifting performance under 40-ton rated capacity.

It is widely used in steel plants, fabrication workshops, machinery manufacturing, and industrial material handling systems.

Key Features

Multi-Sheave Configuration (3 Pulleys)

The integrated three-sheave layout provides:

• Balanced load distribution

• Reduced individual rope stress

• Extended wire rope service life

• Improved lifting efficiency

Heavy-Duty Structural Plates

Manufactured with reinforced side plates to ensure structural rigidity and high load-bearing performance.

High-Strength Forged Hook

The hook is forged from alloy steel and heat treated to provide:

• Superior fatigue resistance

• High impact strength

• Long service life under dynamic lifting

Precision Machined Sheaves

Each sheave groove is precisely machined to match rope specifications, ensuring smooth rope travel and minimal wear.

Safety Latch System

Equipped with a heavy-duty safety latch to enhance operational safety.
