Frequently Asked Questions

FAQs
Are Green Pin® Turnbuckles suitable for lifting applications?

Green Pin® Turnbuckles G-6311, G-6312, G-6313, G-6314, G-6315, G-6323 and G-6333 are suitable for lifting applications. These items have a Proof Load equal to 2 x WLL and Minimum Breaking Load equals to 5x WLL. Of course the “Instructions for use”, as we publish them in our catalogue should be respected at all times.

Note: It is not permitted to adjust the length of the turnbuckle under full load. Tensioning below the WLL is permitted. It is advisable first to adjust roughly the length of the turnbuckle and then load the turnbuckles to a certain tension. The tension may not exceed the full capacity (WLL).

Note: that it is not permitted to lift a load by tensioning (rotating the body) the turnbuckle, as shown in the picture below:

Do not rotate turnbuckle body when lifting

FAQ-Reference PI-02-01. Revision B.

Is it allowed to weld on Green Pin® lifting equipment?

No! Green Pin® products are treated with well designed heat treatment, which results in a certain Minimum Break Load and other specific mechanical properties. These properties will be destroyed by the heat of welding. It even can initiate extreme hard spots and initial cracks, that will decrease the strength and fatigue life dramatically. An exception is made for Green Pin® GH and PAS products, as these need to be welded to a surface to function. For these items, please follow the instructions that are available at Green Pin® sales.
