Rope constructions

There are four main rope types. Each of these has a different balance of properties. It is equally important to select the right construction as well as the right yarn.

1. Parallel Yarn
2. Parallel Strand
3. Stranded (Wire Rope Construction)
4. Plaited & Braided

Parallel Yarn

Construction: Parallel fibres with an extruded polyethylene jacket

Properties

• High Strength Conversion
• Highest Modulus
• Generally Terminated With A Barrel And Spike Termination

Typical Applications

• Antenna Guys
• Mooring

Parallel Strand

Construction: Parallel strands (braided or laid) with a braided fibre jacket (typically polyester)

Properties

• High Strength Conversion
• Highest Modulus
• Readily Splicable

Typical Applications

• Floating Platform Mooring

Wire Rope Constructions

Construction: Strands laid as in a wire rope. Torque balanced constructions also available

Properties

• High Strength Conversion
• High Modulus
• Readily Splicable
• Best Performance in Cycling over Sheaves

Typical Applications

• Mooring
• Dynamic Applications such as Lifting

 

Typical Wire Rope Strand Constructions

Same Dia Wires = Hexagon	Warrington Construction	Warrington Seale Construction

Plaited

Construction: 8 and 12 Plait Braids

Properties

• Moderate Strength Conversion
• Moderate Modulus
• Readily Splicable
• Excellent Structural Integrity

Typical Applications

• Ship Mooring
• General Engineering

Braided

Construction: Single Braid or Braid on Braid

Properties

• Moderate Strength Conversion
• Moderate Modulus
• Readily Splicable
• Excellent Structural Integrity but Softer than an 8 plait Braid

Typical Applications

• Ship Mooring
• General Engineering
