Types of Turnbuckles and Their Functions

Types of Turnbuckles and Their Functions - Have you ever seen an object tied or pulled using a sling? If you pay attention, there is an additional tool attached to the sling. The name of the accessory is a turnbuckle or also known as a hard needle.

A steel sling that is used to tie or pull an object often experiences slack or stretch bonds so that the sling bonds are not optimal and have the potential to come off. Therefore, steel slings used to bind or pull objects are added with an additional tool, namely a turnbuckle. Turnbuckles are very often used in the construction sector to adjust the tension of steel ropes or slings to suit the needs.

What Are Turnbuckles?

Turnbuckle is a tool that serves to adjust the tension, tighten and reduce (loosen) rope, cable, or steel wire. At the end of the turnbuckle there is a fitting that serves as a connection between the turnbuckle and the steel rope.

The end of the turnbuckle fitting connected to the rope or tension system can be tightened or loosened to adjust the tension (tightness) on the connected rope.

The use of turnbuckles can be done alone or together with other turnbuckles to adjust the tension on a particular segment.

Turnbuckle Type

When viewed from the end of the connection (fitting), turnbuckle is divided into several types. The type of fitting is available according to the type of rope and the conditions of connection to the turnbuckle. The following are the types of turnbuckles and their functions based on the shape of the fitting.

1. Hook End Turnbuckle (Hook Fitting)

The hook end turnbuckle (hook fitting) serves as a temporary connection because it can be connected and removed easily and quickly. This type of turnbuckle is more often used in temporary joints. Hook end turnbuckles (hook fittings) are not recommended for connections with dynamic stress loads because the hook end fittings can be disconnected suddenly.

2. Jaw End Turnbuckle (Jaw Fittings)

Jaw end turnbuckle (jaw fitting) is a turnbuckle consisting of a jaw-shaped fitting fastened together by a pin or bolt. Jaw end turnbuckles (jaw fittings) are used on strong joints and can be locked but can be removed if needed.

3. Eye End Turnbuckle (Eye/Round Fittings)

Eye end turnbuckle (eye/round fitting) is a turnbuckle with fittings in the form of closed fittings which can be connected to a certain connection or link easily and firmly.

4. Turnbuckle Fittings Combination

Combined turnbuckle fittings are different from previous types of turnbuckles. If the previous turnbuckle had the same fitting on both ends, the combination fitting turnbuckle has a different fitting shape between one end and the other.

Sometimes under certain conditions a combination of the two different ends of the fitting is required. Examples of end fitting combinations are eye-jaw, hook-jaw, eye-hook and other combinations.

The end combination of the fitting on the turnbuckle is affected by what is connected to the turnbuckle.
