    For some time, there has been a lot of noise around load restraint on vehicles and in particular the use of ropes. There seems to be a love affair with rope, maybe it is the Boy Scout in all of us. So let me clear up a myth, –

    Myth – “The use of Rope will be banned under CoR” Ropes will not be banned under Chain of Responsibility and are able to be used in accordance with the NTC Load Restraint Guide.
    Therefore, now that is cleared up we need say no more and we can use rope as we always have… WRONG, let us explore the Load Restraint Guide.

    The Load restraint guide states:

    “The tie-down force from each lashing is the sum of the lashing tension on each side of the load, multiplied by the angle effect. The tension in any lashing must not exceed the manufacturers’ lashing capacity.”

    So looking at the Manufactures Lashing Capacity, where do you find the tag on the rope that states the Australian Standard and lashing capacity? When did you last see such a tag? Maybe never. But wait; rope standard do exist, again the Load Restraint Guide states:

    4.12 Ropes “Rope designed for use in transport (Transport Fibre Rope) is made from synthetic fibre. Rope made from natural fibre has lower strength than synthetic rope. All transport fibre rope with a diameter of at least 12mm is colour-coded for its lashing capacity. A rope with two black marker yarns has a lashing capacity of 100 kg and a rope with one yellow and one black marker yarn has a lashing capacity of 300 kg. (Note these are the strength of the rope, not the tension achieved when tightening.) Ropes should only be used for restraining relatively lightweight loads”

    So let me ask some questions:

    Q: Do 100% the ropes used in your business have a coloured yarn in them? 
    Yes ❏ No ❏
    Q: Do 100% of the rope users know which colour means what?
    Yes ❏ No ❏

    If you answered no to either question you are in
    contravention of the load restraint guide…
