cromox® stainless steel anchor twister

The cromox® stainless steel anchor swivel is the connecting link between the anchor and the chain. The smooth-running, rotating ball head of the anchor swivel aligns the anchor perfectly. This prevents the anchor chain from twisting and possibly causing damage.

Its special shape and swivelling ball head connection ensures that the anchor is self-aligning during lifting and ensures good adaptation to the anchor roll. The innovative quick-release system makes it easy and uncomplicated to remove or replace the anchor from the anchor chain.;

The most important data at a glance:

  • Material: the 1.4462 Duplex (AISI 318LN) enables use in fresh and salt water and guarantees full functionality at high and low temperatures and degrees of water contamination.
  • Swivel: a smooth-running ball-and-socket connection allows the anchor to rotate without twisting the anchor chain.

Innovative quick-change system makes it easier to change anchors

The innovative quick-change system, which is integrated into the swivelling ball head swivel, enables the anchor to be replaced or removed quickly. Thanks to its rotatability, the anchor swivel enables greater flexibility and efficiency at work.

How the system works: The bolt is loosened using an Allen key, the anchor is hooked in, and the bolt is tightened again. This allows the anchor and anchor chain to be separated quickly and easily.

1.4462 Duplex (AISI 318LN) stainless steel: the optimal choice for fresh and saltwater applications

1.4462 Duplex (AISI 318LN) is a type of stainless steel that is particularly corrosion-resistant and durable. This material is therefore ideal for applications in both fresh and saltwater environments (regardless of the degree of contamination of the water), as well as in the chemical and petrochemical industries and in the offshore sector.

This type of stainless steel combines the best properties of austenitic and ferritic steel, which gives it the name "duplex". The high proportion of chromium, nickel and molybdenum increases its corrosion resistance. It also has a high resistance to pitting and crevice corrosion, which frequently occur in maritime environments. Its high strength, which is about twice as strong as most common austenitic stainless steels, allows the use of thinner materials, which can also lead to weight and cost savings.

FAQs

What are anchor twisters/anchor swivels?

Anchor twisters or anchor swivels are special devices that are attached to the end of an anchor chain between the anchor and the chain. They allow the anchor to twist and turn without twisting the chain. This is particularly useful in situations where your boat is being turned by wind or currents or you are lifting the anchor. By using an anchor twister/anchor swivel, the anchor can swivel freely and adapt to the changing orientation of the boat without twisting the chain. If the anchor swivel is bent, it adapts well to the anchor roller, which makes it even easier to weigh anchor.

Where are anchor swivels used?

Anchor swivels are mainly used in shipping to connect anchors to the anchor chain. They are used to absorb the rotation of the anchor and thus protect the chain from twisting.

Where are Ketten Wälder GmbH anchor swivels manufactured?

Ketten Wälder GmbH's cromox® anchor swivels are manufactured in Germany. However, the company's own production facilities in Bad Endorf in Upper Bavaria are not only used for production on over 5,500 square metres, but also for careful testing in the company's own Lloyd's Register-certified test laboratory. Over 1,000 different product solutions for lifting and moving loads are dispatched from the company's own factory to over 50 countries worldwide.

What are the advantages of stainless-steel anchor swivels?

Anchor swivels made of stainless steel (inox) are resistant to corrosion and rust, making them ideal for use in maritime environments. They also have high strength and can withstand high loads, which extends their service life. They require less maintenance than anchor twisters made of other materials as they are easy to clean. They are also aesthetically pleasing: an aspect that is important to many boat owners.
