Structural-Inspection

Structural Inspection

  • Dimensional Accuracy: Use precise measuring tools to check the dimensions of ladder components, ensuring they meet design specifications.

Load Testing

  • Static Load Test: Secure the ladder on a test platform, gradually increase the weight up to 1.5 times the rated load to ensure the ladder does not deform or crack under high loads.
  • Dynamic Load Test: Simulate user movement on the ladder, repeatedly adding and reducing weight to test the ladder's load capacity and structural stability.
  • Long-term Load Test: Apply the rated load on the ladder for a specified duration to observe any deformation or damage, ensuring its durability and stability.

Surface Treatment Inspection

  • Anti-slip Performance Test: Test the anti-slip performance of the ladder steps to ensure user safety in various environments.
  • Corrosion Resistance Test: Test the ladder's surface for corrosion resistance to ensure its durability in humid and corrosive environments.

Safety Testing

  • Safety Lock Test: Conduct repeated opening and closing tests on the safety locks of foldable ladders to ensure their reliability during long-term use.
  • Stability Test: Simulate real-world scenarios to test the overall stability and anti-tipping capability of the ladder, ensuring safe use on various ground conditions.
