Green Pin® Web Sling Shackle SC

Shackle for synthetic web slings with screw collar pin
  • Shackle crown optimized for web sling
  • Extends lifespan of web sling
  • Smooth finish
  • No WLL reduction on the web sling required
  • Chamber in the shackle eye hides the screw thread and reduces wear

The Green Pin® Web Sling Shackle SC is the ideal shackle for lifting with synthetic round and flat web slings. The optimal bearing surface of the shackle crown means the load on the web sling is distributed evenly. As a result, damage to the web sling is minimized and its lifespan extended. Wear of the web sling is also minimized as a result of the smooth finish of the shackle. Furthermore, because the load is distributed evenly on the web sling compared to a standard shackle, it is not necessary to reduce the load (WLL) on the web sling. The risk of damage to the web sling that touches the pin is also significantly reduced because the screw thread is completely hidden into the shackle eye. The product is suitable for web slings made according to EU and US standards. The shackle is available in a range with a working load limit from 3.25 up to 8.5 ton.

Frequently Asked Questions

Where can I find CAD drawings of Green Pin® products?

If you go to the product pages of individual products on this website, you can download the CAD-drawing (3D) of that product:

  • On the product page, go to the table with dimensions
  • Select the productsize that you are interested in
  • A Download button will appear

If no Download button appears, no CAD-drawing for this product is available.


Are there any recommendations for additional stamping on Green Pin® Shackles?

Note: Main dimensions, general info and warnings can be found in our latest catalogue.

If the recommendations in this product information are followed performance of the shackles is guaranteed:

  • permanent identification marks, or symbols, are to be made by dot peen marking or with stamps having rounded profiles (low stress stamps).
  • the number of marks on a shackle is to be kept to the minimum.
  • the use of fractions and oblique strokes is to be avoided and a dot or hyphen is preferable to a dividing line.
  • values of WLL are, generally, to be marked to one place of decimals (except for 0.25 and 0.75) up to 100 t and in integers thereafter. The word “tonnes” may be abbreviated to “t”.
  • recommended sizes of marks are
    • Diameter of part to be marked > recommended size of mark
    • less then 12.5 mm > 3.0 mm
    • 12.5 to 26 mm > 4.5 mm
    • over 26 mm > 6.0 mm

Typical arrangements of marks can be found in the following illustrations.

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.

FAQ-Reference PI-07-02 Rev. B

Are there any recommendations for the inspection of shackles?

It is required that shackles are regularly inspected and that the inspection should take place in accordance with the safety standards given in the country of use. This is required because the products in use may be affected by wear, misuse, overloading etc. with a consequence of deformation and alteration of the material structure. Inspection should take place at least every six months and even more frequently when the shackles are used in severe operating conditions.

Shackles should be inspected to ensure that:

  • all markings are legible;
  • the body and pin are both identifiable as being of the same size, type and make;
  • the threads of the pin and the body are undamaged;
  • for a safety bolt type shackle is used with the split cotter pin;
  • the body and the pin are not distorted or unduly worn;
  • the body and pin are free from nicks, gouges, cracks and corrosion;
  • shackles are not heat treated as this may affect their Working Load Limit;
  • the shackle is not modified, repaired or reshaped by welding, heating, machining or bending as this will affect the Working Load Limit;

Remove the shackle from service if:

  • all markings are not  clearly legible;
  • body and pin can not be identified as being from same size, type and make;
  • the threads of the pin and/or body are damaged;
  • for a safety bolt type shackle the split cotter pin is missing;
  • the body and/or pin is distorted or unduly worn, the maximum allowable wear is 10% of the original dimension;
  • the body and/or pin is not free from nicks, gouges, cracks or corrosion;
  • the shackle has been exposed to any heat treatment;
  • the shackle is modified, repaired or reshaped by welding, heating, machining or bending;
  • t is expected that before the next periodical inspection any of the inspection criteria above will not be passed;

We have redesigned the entire range of Green Pin® screw pin shackles, what's new?

In the past, one or two pitches of thread were often visible on the shackle pin next to the threaded shackle eye. Earlier design, after assembly some of the threading is visible at the shackle eye:

Green Pin Screw Pin Chambering

Today, we machine a small chamber in the treaded eye of all our Green Pin® shackle bodies for screw pin shackles.

Green Pin Screw Pin Shackle Chamber

The thread is now fully covered by the shackle eye, leaving the bearing surface of your shackle pin entirely smooth. This is good news for your counter components like soft slings or steel wire ropes: they can no longer be damaged by any threading on the shackle pin.

This modification is fully incorporated in our product designs, meaning the products comply with all standards and certifications mentioned in our catalogue.
