Q: Do ‘tie-down’ straps need a certificate?
A: No they do not, however, they do need to carry a rating label showing the Lashing Capacity & the STF (Standard Tension Force) of the ratchet. Read more about Tie-down ratchet straps
Q: Should you check webbing straps regularly for damage?
A: Yes you should, because even a small cut or tear can reduce the strength of the strap significantly.
Q: What do the lines of stitching mean in webbing straps?
A: The number of lines in webbing should equal the strength eg 5 lines = 5 tonnes minimum break load. This is not always the case. Read the manufacturer's label sewn into the webbing strap!
Q: Can I repair my chain & winch hooks?
A: Yes if your hook is an alloy or G80 hook which has a catch that has been damaged or lost, you can buy a new catch.
Q: What are Slippery Jim’s?
A: There are 2 types on the market today. One is interlocking so the skates can be joined together (Wreckmaster Skate). The other is a smooth solid construction called the Easi Skate. Both types aid the recovery of vehicles when winching up onto a truck bed.
Q: How is winch rope constructed?
A: There are 3 main types of wire rope in us today: 6x7, 6x19 & 6x36. This means that the rope is made up of 6 bundles of wires with 7, 19 or 36 wires in each bundle. The more wires there are in a rope the more flexible the rope is. Rope then either has a wire or fibre core that runs down the centre of the rope. Cardno only uses 6x36 wire steel core for maximum strength & flexibility. Read more about Winch Ropes
Q: Why does my winch rope have a stamped SWL that seems to be lower than it should be?
A: Wire rope has to be rated for lifting, which requires a minimum break strength to be divided by 5 eg: 10mm (6x36) 1960 N/MM2 has a min break load of 7113KG and a Safe Working Load of 1423KG
