Future Proof Your Lifting Tackle

It's not exactly brand new in the lifting gear universe, but the grade 12 chain is now proving to be the future of chain sling systems, with major crane companies re-equipping their mobile cranes with significantly lighter slings.

Are you ready to change?

Grade 12 Winner Pro Chain

Thanks to the intelligent use of material, the same cross-section achieves a marked improvement in the chain's key characteristics, such as fatigue resistance and bending resistance, compared to conventional round-steel chains.

The material was optimised in key areas and reduced in less relevant areas to achieve the best possible technical effects.

The moment of inertia is crucial for the properties. The chain is up to 6% higher in a profile chain than in a round-link chain with the same cross-section. For the user, this results in a higher degree of safety in case of edge-loading, which in practice is frequently misjudged, resulting in the chain's failure.

User benefits at a glance:

50% higher working load limit compared to Grade 8.
20% higher working load limit compared to Grade 10.
Your slingers' will love it's lighter-weight and ease of handling.
You will benefit from cost savings through improved sling life and less downtime.

Changing to Grade 12 means it is almost always possible to use a smaller chain sling by one nominal size compared to G8, saving weight and cost and making the slinger's task easier.

The Pewit Winner Pro Chain System includes clever design in chain sling technology with

Oversize master Links

Although the chain size is smaller than the equivalent older systems, Pewag did not want to compromise on the master links and use larger rings that are perfect for crane hooks, according to DIN 15401.

The new oversized lifting ring stands out for its asymmetrical shape and is suitable for assembling II- and IV-leg chain slings in the assembled system. The upper curve's improved design optimises the assembly's contact surface on the single crane hook.

The great plus of this master link assembly is the geometry of the lower area, which, especially for II-leg chain slings, enables the easy, fast assessment of the working load limit based on the position of the attached transition links. Thus, it greatly increases safety and efficiency during day-to-day operations and eliminates miscalculations.

Connex Connecting Links

This is a universal connecting link that consists of two die-forged, identical halves, a pin and a safety sleeve. It is manufactured according to EN 1677-1 with a working load limit according to G12. The connecting link is constructed in such a way that the PWP shortening hook may be adjusted in one half together with the chain, enabling the cost-efficient assembly of a chain sling with a shortener.

PWP Grab Hook

Perfect for chains and slings, the standard shortening hook with BG approval in the G12 programme is perfect for the Connex system. When shortened, this hook does not require reducing the working load limit. It corresponds to EN 1677-1 with the working load limits of G12.

KHSWP Clevis Sling Hook with Safety Latch

This is a hook in the Pewag Winner Pro G12 range. It has a considerably larger jaw size but is comparatively light in weight.

It is manufactured according to EN 1677-2 with the mechanical values of grade 12 and may be mounted directly in the chain in the Pewag winner pro clevis system without the need for a connecting link. The forged safety catch locks into the hook's tip, providing excellent protection against lateral shifts. The safety catch mechanism and the clevis load pins are available as spare parts sets and are easy and quick to exchange by a competent person.

The forged control markings make it easy to determine discard criteria—yet another great advantage of this Clevis hook! This product comes with BG approval. Note: The KHSWP clevis hook may also be used for lashing operations. For more information, please contact us.

KLHWP Clevis (Self-Locking) Safety Hook

The great advantage of this clevis safety hook is that it closes and locks automatically under load, thereby preventing unintentional opening while under load and providing additional safety during day-to-day operations. The larger jaw opening provides additional versatility and flexibility.

The clevis safety hook is manufactured according to EN 1677-3, with mechanical values for G12. It comes with BG approval.

The safety hook comes with CE marking and exchangeable spare components.

KLHGWP Oversize Clevis (Self-Locking)

These safety hooks have innovative features that simplify handling and control and broaden the application range simultaneously.

The recessed trigger prevents accidental opening, and the special design makes opening due to impact stress practically impossible.

Its large jaw opening ensures almost unlimited connection options for the hook and a wide range of loads. The low weight further emphasises all the benefits of grade 12 – straightforward handling thanks to lower weight.
