BRUGG Lifting - Drahtseile und Stahlseilen

How is a wire rope constructed?

Steel wire ropes are constructed from a large number of steel wires. The single steel wires are converted into strands. Afterwards, several strands are stranded to form one rope core around which the outer strands are laid in a final stranding process.

Some rope constructions feature plastic inserts. For this purpose, the final stranding is preceded by a further production step during which a special procedure a plastic coat is applied onto the rope core. It is of course important to establish a sufficient amount of lubricant in the inner layers of the rope.

Selection of the appropriate wire rope

When selecting the appropriate wire rope, you must consider the rope properties, the type of the rope and the rope end connections. Here we give you an overview of the key aspects and selection criteria.

If you need further information about how to select the appropriate wire rope, we will assist you. Just contact us by telephone or email.

Rope properties

The key rope properties to be considered when selecting the appropriate wire rope include the rotation freedom and the direction of lay.

Rotation-free or non-rotation-free?

This decision must be made very carefully. There is no room for error. Short rope service lives, changes to the structure of the rope, abrupt and unexpected failure of the rope, etc. could result from a wrong choice.

Rotation-free ropes

Rotation-free ropes must be selected when lifting an unguided load on a single rope line or when lifting an unguided load on several rope lines at great lifting heights. Rotation-free ropes can be used with or without a swivel.

Nicht drehfreie Seile von BRUGG Lifting

Non-rotation-free ropes

Non-rotation-free (non-twisting, rotation-resistant) ropes must be selected when lifting guided loads, when lifting unguided loads on several rope lines at small lifting heights (e.g. electric hoists) or when lifting loads with right-hand and left-hand ropes operating in pairs. Non-rotation-free ropes must not be used with a swivel.

What is a rotation-free wire rope?

A steel wire rope is considered as rotation-free, if the rope under the influence of an unguided load does not, or does barely, rotates around its longitudinal axis and exerts a very low torque on the end connections. This characteristic results from the fact that direction of lay of the rope core is opposite to the direction of lay of the rope itself. Thus, when a rotation-free rope is under load, the torque generated by the core is equalized by the torque generated by the outer strands.

What is a non-twisting wire rope?

A steel wire rope is considered as non-twisting if, when the rope is cut, the wires do not, or do barely, pop out of the rope structure even without the rope being served and the pulled rope remains straight without resilience.

Schlagrichtung (Gängigkeit) des Drahtseils

The correct direction of lay

The direction of lay of the rope is the direction of the helical line of the outer strands, where we distinguish between right-hand lay and left-hand lay. Both the rope and the strands feature a direction of lay.

Drahtseil - Kreuzschlag

Ordinary lay

The wires in the outer strands are laid in the opposite direction to the lay of the strands in the rope.

Drahtseil - Gleichschlag

Lang lay

The wires in the outer strands and the strands in the rope are laid in the same direction.

As a general rule according to DIN 15020, for a grooved drum having a right-hand pitch a left-hand lay rope should be applied. Accordingly, for a grooved drum having a left-hand pitch a right-hand lay rope should be used.

The appropriate type of rope

The rope application determines the wire rope construction that may be used.

  • Use spiral ropes for static or virtually static applications
  • Use stranded ropes for all normal rope drives
  • Use spiral ropes with round strands for rope drives requiring a rotation-resistant rope

Rope end connections in comparison

Most end rope connections will reduce the minimum breaking strength of the ropes. The overview shows some common designs with the remaining minimum breaking strength of the rope in %.

...the various discard criteria for wire ropes?

These include wire breaks, broken strands, reduction of the rope diameter due to internal or external wear, internal or external corrosion, decrease of elasticity, deformations, waviness, bird-caging or protrusion of the core or parts thereof, protrusion of wires from the outer strands, rope swelling, damage caused by heat, crushes, flattened spots, kinks, bends or similar damage.
