Frequently Asked Questions

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

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.

How can I make a safe connection to a Master Link?

When using chain to connect an eye hook to a master link, at least three chain links must be used. Alternatively they may be connected by a connecting link only, without any chain in between.

Where can I find the DGUV Type Approval?

DGUV Type Approval
Van Beest puts great emphasis on the quality of products. Recently, we have renewed our DGUV Type Approvals for many of our products. This allows us to H-stamp the components with our unique H number (H94).

DGUV (Deutsche Gesetzliche Unfallversicherung / German Social Accident Insurance) is the umbrella association of the accident insurance institutions for the industrial and public sectors, a leading certification association in Europe.

The test procedure includes verification of materials, verification of the dimensions on individual samples, tensile tests, fatigue tests and some specific tests such as a bending test, a latch lock test and a latch strength test. The results are compared to the specifications mentioned in the EN 1677 norm. With this comprehensive testing procedure and certification of both chain and components, Van Beest supplies the highest quality products that contribute to a safe working environment.
