The FlexiLeg concept allows you to add or remove one- or two-leg slings, as required. This gives the user flexibility and also removes the temptation to hook unused legs out of the way and guess the WLL—the tag shows the WLL for all four versions.

Many users look at it as having various ways to use one- and two-leg slings.

For example, if you have a single pick point, use a one-leg sling; if you want a two-leg sling, take the one-leg off and add a two-leg; if you want a three-leg, add the one-leg back; if you want a four-leg, take the 1-leg off and replace it with a two-leg.

Are you rigging with multiple pick points?

Would using multiple pick points made your lift safer and more secure?

A Gunnebo Industries GrabiQ oblong master link connects multiple Grade 10 slings, using a master grab or a dual master grab, for example.

Every link of the Grade 10 chain is calibrated and pull tested to 62% of the minimum breaking force.

The GBK self-locking hooks will act as a gauge to signal an unsafe, bent hook or latch.

Downloads FAQs

1. What are self-locking hooks? As the name suggests, self-locking hooks close by themselves as soon as a load is placed in the bowl of the hook and lifting begins.

2. Why are self-locking hooks safer? Once it closes, it cannot open again until the load is released from the hook.

3. What is the difference between self-locking and safety hooks? Self-locking hooks are sometimes called safety hooks. They are usually the same thing.

4. When was the self-locking hook concept launched? The self-locking hook concept was launched as the BK model by the then Gunnebo Industries in the 1960s, primarily to improve safety on construction sites where, previously, hooks were being rigged without any latch at all.

8. What is the GrabiQ concept? Gunnebo Industries' GrabiQ combines multiple functions in a single component. The FlexiLeg concept allows you to add or remove one- or two-leg slings, as required. This gives the user flexibility and also removes the temptation to hook unused legs out of the way and guess the WLL—the tag shows the WLL for all four versions.

9. Why would I use this system over others? A four-leg top assembly is traditionally 15 pieces; with GrabiQ, we can reduce that to three pieces only.
