Swivels

A swivel is a metal device for connecting mechanisms to each other. A swivel is used to connect a lifted load to other components of a rigging system.

This is a universal and reliable method of connection. The products are made of high-alloy AISI 316 steel, which ensures rotation of the ring, jaw, or snap hook relative to the opposite part.

Design

There are 2 common types of swivels:

• Eye-eye — a non-detachable type, consisting of a pair of closed rings or eyes and a connecting rod;
• Jaw-jaw — a detachable element, installed with either side facing the links or lugs by opening a pin with a special thread.
• Eye-jaw — a hybrid design between the two previous types.
• Swivel with snap hook — a variant for securing flexible rigging attachments. May include mounting elements from those listed above.

Structurally, swivels consist of a pair of rotating blocks joined together on a hinge. This compensates for the rotation of a rope or cable.

Operational features

Swivels with snap hooks are used to compensate for the rotation of a rope or chain, which prevents kinks and loops. These devices are used when installing load-bearing structures, wires on power line towers, utilities, and as a rigging element. They are often used together with snap hooks.

These elements are also used for household and everyday tasks: securing fishing tackle, door and gate mechanisms.

Material

Swivels are made of high-strength stainless steel. The material is resistant to mechanical and other loads, which prevents breakage and ensures safety during installation. AISI 316 steel is most often used, as it offers high corrosion resistance and durability for use in damp environments.

This material withstands chemically aggressive environments. The service life of the product exceeds 10 years. The device allows for repeated use.

How to choose correctly

When choosing a swivel, consider the operating conditions and the load factor for the element — this allows you to calculate the maximum mass of the load that can be secured to the swivel. The strength of the assembly depends on the quality of the product, so swivels made of high-strength steel should be chosen.

The type of swivel is selected individually based on the operating conditions in each specific case.
