About The Wire Rope Slingwire rope sling options

Wire-rope slings offer the user an alternative lifting means to the usual chain sling with the main benefit being that if one or 2 wires or strands break, the load will usually hold on its remaining, intact wires/strands until it is set down safely, whereas with a chain sling, if a link breaks the load falls.

Wire-rope slings need to be made and used in the correct manner to prevent damage, non-rotating rope ordinary or regular lay rope is the preferred wire-rope for slinging as they are not prone to unwinding when twisting against the load, (Lang’s lay rope can easily unravel when under load unless fixed correctly at both ends) they can successfully be utilised in a straight lift, basket hitch or a choke hitch, however the safe working load will need to be de-rated when used in a basket or choke hitch according to the recommended safe use of documentation.

We can supply endless slings as well as 1, 2, 3 or 4 leg slings in any length with any fittings to best suit your requirements, the images show just the most common configurations.

Rope Services Direct have all their own machinery allowing us to tailor make a chain sling to suit your application; we can press any fitting onto your chosen wire rope, whether it be a hook or thimble with links. We can also add tubular wear sleeves to add extra protection to the wire rope and stops, if needed. Call our sales team with your requirements today or contact us by email on our contact form.

Types of Wire Rope Slings

Wire rope slings are robust pieces of equipment used for lifting applications.  Wire rope slings are widely used within the lifting gear and engineering industries, frequently used to lift extremely heavy loads. Used not only on hoists, but also as crane rope on the huge cranes we see at dock yards and large construction sites.

Like chain slings they are available in single leg or multi leg models; however whereas a chain sling relies on each link for strength a rope sling has countless wires to hold the load, consequently when using a chain sling if 1 link breaks the whole chain sling will fail, but with a sling if 1 or 2 wires break the whole rope will not catastrophically fail as the remaining countless intact wires will still usually support the load until it can be lowered safely.

As there are many types of wire rope constructions the rope must be chosen very carefully for its intended application because some will undoubtedly have more limitations than others. A rope sling will need a good amount of flexibility, especially if it is to be used in certain hitch types, single or multi-leg slings where the rope is used in a straight line connection from the master link to the load may need less flexibility.

A less flexible or stiffer wire rope will have more crush and abrasion resistance than a very flexible one; and can also be guided under loads and pallets which can make lifting tasks much easier.

So with the above in mind it is important to verify how you will need to utilise your rope sling before purchase so you can choose the most suitable construction type for its intended purpose.

The Safe Use of Slings


Here we take a brief look at using a wire sling in a safe manner.

When using a wire rope sling you should:


ALWAYS:3 leg wire sling

  • Check over all equipment prior to each use
  • check the master link fits without restraint onto the lifting device
  • Allow for the method of use/ type of lifting application when choosing the sling
  • Position the hooks on multi-leg slings so they face outwards, away from the load
  • Hook back any un-used legs securely into the master link to avoid lashing and serious accidents
  • confirm the wire has NO kinks or twists
  • Make sure the diameter of pins , hooks etc. where soft eyes will rest are at least twice the diameter of the wire rope’s diameter
  • Use suitable wadding around sharp edges to guard the wire rope from damage.
  • Place the spliced ends on endless slings clear of hooks and fittings.

NEVER:

  • Lift on the tip/point of a hook (slings should seat in the bowl/bottom of the hook)
  • Knot or tie wire rope, or try to shorten them
  • Force wire rope slings into fittings
  • Join ropes with different direction lay’s, unravelling will occur.
  • Use at temperatures over 100 degrees or below 40 degrees, contact supplier first.
  • Use where chemicals are present
  • Overload the wire rope sling

Maintenance for wire rope slings is usually minimal, if treated with respect;  storing them correctly – hung up, not left on the ground,  keeping them clean and re-lubricate with appropriate materials when necessary and handling them in the correct manner  will ensure a long working life.

Inspections of slings should be carried out on a regular basis whilst in-service, to identify any impending problems which could severely affect the performance of the wire rope. These thorough inspections are to comply with LOLER regulations.

An experienced person should look out for the following:

  • Wear, cracks, distortions, corrosion, discolouration's
  • Movement at end terminations
  • Broken or cut wires
  • Kinks
  • Protrusion of the core
  • Broken or missing safety catches
  • Un-readable markings
