Took test broke 11 of tow rope!

Tow ropes, unlike first-aid kits and fire extinguishers, carry a optional. But in almost every trunk they lay, just in case.

Their efficiency usually is beyond doubt, because the coupling of tanks no one is going. If the packaging says “five tons”, then almost any car with a stock enough.

Such cables acquire without much thought, so that’s what we chose to test 11 different trailing cables‑patimonio.

The so-called jerk the cables were not acquired — they have their own specific work.

Methods of testing

To test the cables, decided in the most exemplary way — in the gap. For this we used universal tensile machine R‑20, hydraulic actuator which develops a force up to 200 kN (20 tons). Recorded as the value of the effort gap and the nature of the deformity: it is unknown which part of the cable will be the weakest of his body or hook.

Ropes cling to the hooks, because that is how we use them. And in those cases where hooks had died first, for the sake of interest were checked separately the body of the rope.

The Dinghy envy

Fido famously tore up a heating pad. And we broke the tow ropes. And results brought to the table.

The force of five tons (5000 kgf) tensile machine was never developed: the cables were eager for loads from 500 up to 2400 kgs. Two of them straightened hooks, and this is the worst: hook, drawn spring wire, can cause a severe blow even in glass, though in the head. So I suggest: first, in the towing eye thread the rope folded in half near the hook, then insert hook in a loop. Get a kind of pulley, which will reduce the load on the hook, and in case of breakage of one will not fly a deadly projectile.

Back to pounds and breaks. All cables were broken with much less effort than the five tons. Does this mean that they are not suitable for towing a five-ton vehicles? There is no single answer.

When towing a car on smooth asphalt just a few hundred pounds of effort. After all, to roll a heavy truck is much easier than to raise it, because the resistance force is determined by the weight multiplied by the coefficient of friction, which is much less than unity. (Visual confirmation of known publicity stunt with a passenger airliner towing a car.) But at the slightest deviation from the “ideal” (road slope, a sharp jerk, not to mention the car on a track) the load on the rope increases dramatically. So experienced Jeepers choose ropes with a breaking load that exceeds the weight of the car.

Suppose the manufacturers of the cables wanted to say that their products are suitable for towing vehicles weighing five tons on a flat road and without a strong jerk. Well, with luck, weak cables can withstand. But if you want to hedge, we recommend that the products withstand the maximum load is Airline ATR-P‑5 and “Hitchhiking Rope”. First, they showed the best results. Second, the stand and more solid load, if fixed on the principle of pulley.

It looked like rathnapriya hook from the tow rope “Hitchhiking Rope GOST AV‑ТО6”. It surrendered the hook often causes damage and injuries.It looked like rathnapriya hook from the tow rope “Hitchhiking Rope GOST AV‑ТО6”. It surrendered the hook often causes damage and injuries.

Such flags should be provided with all the tow ropes. But alas! We bought them separately at a price of about 300 rubles per pair. To mount the box to the tug is very simple: it is enough to “straighten”, to throw the cable and again “bend” Velcro will lock both halves.Such flags should be provided with all the tow ropes.

As for the other parameters of the cables, none of them meets the requirements of the traffic rules: they are no warning flags or flaps are applied with diagonally alternating red and white retroreflective stripes. Flags sold separately – by the way, the product is not the most popular and expensive. Apparently, it was the price and provokes the manufacturers of the cables to the disregard of the requirements of the Regulations.

Wish to purchased the cable never come in handy!

WHAT IS SAID IN THE SDA?

According to paragraph 20.3 of the Rules of the road when towing on a flexible coupling must be ensured the distance between the towing and towed vehicles within 4-6 m, and when towing rigid hitch — no more than 4 m. in addition, in accordance with paragraph 9, “Basic provisions for the admission of vehicles to operation” on a flexible connecting link must be installed at least two warning devices in the form of flags or flaps of size 200 × 200 mm with applied diagonally red and white alternating stripes with a width of 50 mm with retroreflective surface.

  • No tow rope? Here are seven unexpected substitutions.
  • It is important not just the presence of the tow rope in the trunk of the car, but its quality! Towing and jerk the cables and accessories presented in our online store.
