Beaver G1570 6 x 7 Wire Rope, Fibre Core, 2 mm, 100 m Reel (707302-100)

Beaver 6 x 7 G1570 wire rope is galvanised steel wire rope with six strands of seven wires laid around a fibre core in right hand ordinary lay (RHOL), listed by Beaver as dry lube. This listing is the 2 mm rope on a 100 m reel (code 707302-100).

Beaver says more load bearing wires in a rope give greater flexibility, while smaller wires give less abrasion resistance. With seven larger wires per strand, a 6 x 7 rope is less flexible than a 6 x 19 or 6 x 24 of the same diameter but its wires are bigger, so by that rule it has more abrasion resistance. Beaver's manual says the core is the foundation for the strands and keeps them in place through the life of the rope, and that a wire rope core (WRC) is approximately 7.5% stronger and 11% heavier than a fibre core (FC).

Where this product is used

• Towing and lifting applications, as Beaver describes its wire rope range (manufacturer-stated)
• Applications where a fibre core rope with fewer, larger wires per strand is acceptable; Beaver says smaller wires give less abrasion resistance and more wires give more flexibility (manufacturer-stated)

Features

• Construction 6 x 7 with a fibre core, right hand ordinary lay (RHOL) (manufacturer-stated)
• Grade 1570 galvanised wire (manufacturer-stated)
• Listed by Beaver as dry lube (the term is not defined by Beaver)
• Minimum breaking force 2.1 kN (manufacturer-stated)
• Diameter, MBF, mass per 100 m and reel length listed by Beaver (manufacturer-stated)

Reading the specifications

• Nominal diameter: Beaver says this is measured at the widest point of the rope (over the crowns). Choose thimbles, ferrules, grips and sheaves for the rope diameter.
• Construction: six strands of seven wires each, laid around a fibre core (6 x 7 FC).
• Grade: the tensile grade of the wires in megapascals (MPa). Beaver says a higher grade gives a higher minimum breaking strength but also influences the life of the rope.
• Lay (RHOL): right hand ordinary lay, with the strands laid to the right and the wires in each strand to the left.
• MBF: minimum breaking force in kN, as listed by Beaver. This is not a working load limit.
• Approx. mass: kilograms per 100 m of rope, as listed by Beaver.

Lubrication

Beaver's manual says wire rope is lubricated at the time of manufacture, which reduces friction between the wires and strands and between the rope and the drum or sheave, and that the lubrication retards corrosion and inhibits rotting of a fibre core. Beaver lists this rope as dry lube and does not define the term.

Breaking force and working load

MBF is the minimum breaking force Beaver lists for the rope, in kilonewtons (kN). It is not a working load limit. Beaver does not publish a working load limit for loose wire rope, and the load a rope can safely carry depends on how it is terminated and rigged and on the safety factor your application needs. If the rope will be used for lifting, have a qualified rigger or competent person confirm the rope, the terminations and the working load limit before you order, and inspect the rope before each use. Beaver's manual has a working load limit table for standard galvanised slings made from grade 1770 steel core rope, with AS 1666.1 and AS 1666.2 cited in the table heading (manufacturer-stated). That table is for slings and does not cover the rope on this page.

Key specifications

Codes, diameters, breaking forces, masses and reel lengths are from Beaver's Materials Handling Technical Manual (Vol. 4) and the Beaver website. MBF is the minimum breaking force, not a working load limit.

Selecting the right option

Choose the diameter and construction for your application, then check the breaking force against the safety factor you need. Match thimbles, ferrules, grips and sheaves to the rope diameter.
