Steel Hook Bending Tester Machine
1. Product Introduction & Applications
The Steel Hook Bending Tester Machine is designed to evaluate the bending resistance and durability of steel hooks. It performs standardized bending tests to ensure hooks meet quality and safety requirements.
Applications:
Steel hooks in industrial, construction, and hardware applications
Quality control of hooks for load-bearing and safety-critical use
Inspection of hook material integrity after repeated bending
Test Principle:
The hook is inserted into the fixture and rotated 180° around a cylindrical column with a diameter of φ10 mm. After bending, the hook surface is inspected for cracks, fractures, or deformation to determine the product’s bending resistance and overall quality.
