More Information

The patented self-locking pin features a shackle body and indentations to accept the pin lugs. During the final tightening turns the lugs push up against the sprung body. When aligned with the indentations, the pin is prevented from turning unless force is applied by hand.

The hot drop-forged process provides increased strength and manufacturing consistency. Each shackle is CE marked in accordance with the Machines Directive 2006/42. Therefore, Wichard products can be used in lifting applications.

Each product displays the following information:

  • Working Load Limit (WLL) = 5:1 safety factor of the break load
  • CE marking
  • Product origin
  • Manufacturer’s logo
