Pulling Hook / Tension Hook

1. Product Overview

The industrial Pulling Hook, also known as Tension Hook and Mold Pull Hook, is a heavy-duty mechanical pulling accessory designed for tension traction, stripping, demolding, and equipment disassembly operations. It serves as a core connecting tool between pulling equipment and workpieces, widely adopted in mold manufacturing, automobile maintenance, mechanical engineering, factory equipment overhaul, and hardware hoisting industries.

Different from ordinary decorative hooks, this pulling hook is specially engineered for concentrated tensile force. Every unit undergoes strict heat treatment and load testing to ensure stable and reliable performance under long-term heavy-load working conditions. It solves common industry pain points such as hook deformation, brittle fracture, and insufficient bearing capacity of ordinary iron hooks.

2. Core Features & Advantages

• High-Strength Alloy Steel Material Adopts premium carbon alloy steel raw material, which features ultra-high tensile strength, excellent toughness, and strong anti-fatigue performance. It is not easy to break or deform during frequent pulling and tensioning work, far superior to ordinary low-carbon steel hooks.
• Professional Heat Treatment Process Integral quenching and tempering heat treatment is applied to eliminate internal material stress, improve overall hardness and toughness balance, and effectively prevent sudden fracture caused by stress concentration during pulling operations.
• Precision Machining & Smooth Surface CNC precision machining ensures uniform hook opening, smooth arc transition, and no burrs. The polished hook body will not scratch workpieces, chains, or shackles during use, reducing equipment wear.
• Stable Load-Bearing & High Safety Factor Strictly manufactured in accordance with industrial safety standards, with a safety factor up to 4:1. The actual breaking load is 4 times the rated working load, ensuring safe operation under normal working conditions.
• Anti-Corrosion & Durable Surface Treatment Optional black oxide or galvanized surface treatment effectively isolates air and moisture, prevents rust and oxidation, and adapts to complex working environments such as workshops, outdoors, and humid factories, greatly extending service life.
• Universal & Easy to Use Standardized size design, compatible with most shackles, lifting chains, tensioners, and hydraulic pulling tools on the market. The compact and portable structure allows quick connection and flexible operation, improving overall work efficiency.

3. Wide Application Scenarios

This industrial pulling hook is versatile and suitable for various heavy-load tension and traction scenarios:

• Mold industry: Mold demolding, mold splitting, mold handling and tension fixing
• Automotive maintenance: Vehicle frame correction, part pulling and disassembly, sheet metal shaping
• Mechanical engineering: Equipment resetting, component traction, heavy object positioning
• Hoisting and handling: Auxiliary connection of small and medium-sized heavy objects, tension positioning
• Factory overhaul: Mechanical component disassembly, stuck part pulling and resetting

5. Safety Operation Instructions

• Strictly Prohibit Overload: Do not exceed the rated working load during operation to avoid hook deformation or fracture.
• Pre-Use Inspection: Check the hook body for cracks, wear, deformation or rust before each use. Stop using immediately if abnormal conditions are found.
• Standard Connection: Ensure the hook is fully locked with matching accessories to prevent slipping and falling during tensioning.
• Avoid Abnormal Force: Do not apply sudden impact force or oblique pulling force, keep vertical and stable tension.
• Regular Maintenance: Clean and lubricate regularly, store in a dry environment to avoid long-term corrosion affecting bearing capacity.

6. Product Highlights Summary
