Compared with other structural equipment, its price is cheap, light in weight, and easy for daily driving. The important thing is that the structural effect is simple and direct, which can be said to be a structural equipment with high cost performance.
Cover tow ropes, convoys, trailers
1. Many riders who don't know much about off-road structure may have come up with such a trailer.
The non-professional traction rope is equipped with metal objects at both ends, which is very dangerous during emergency rescue. The collapse of the traction rope will generate a strong elastic force. If the traction rope with metal joints breaks, it is likely to cause casualties.
2, or the kind of
Sling trailer belt
There may not be much difference in appearance. Look at the hangers. The thickest one might be 1cm thick and maybe 10cm wide. Looks heavy and sturdy. but it is not the truth. Off-road trailers are fundamentally different from trailers or regular trailers.
In the four-drive configuration, the vehicle is usually stuck in cover or in a quagmire. Taking quagmire as an example, the mud has certain adsorption properties. If you have the experience of accidentally stepping on the mud, you must be familiar with it. The feet are out of the shoes and feel still in the mud.
If we use a harness, because the harness has no elasticity, the vehicle has a certain initial speed on the trailer, and the rope is instantly tensioned. Because there is no cushioning, there is no plop, the car may not have pulled out, the rope may have broken first, and the trailer beam behind it all pulled up.
According to the hoisting industry standard, a 5-ton sling generally bears 4 to 6 times the traction force during operation. That is to say, it can withstand up to 30 tons of traction without crashing. But this number refers to the maximum breaking force that can be withstood at rest, not an instant huge impact, so it's not that the quality of the rope is not enough, but that it is not suitable for this kind of shocking work.
Advantages of tow straps
A tow strap isn't just sturdy, it's as simple as a tow truck. It is scientifically designed, with good ductility, and the length under load should be extended by 20%. This elastic elongation is very useful during construction.
1. When the rescue vehicle rushes forward, the trailer belt can be fully expanded to protect the rescue and rescue vehicle chassis from powerful instantaneous shocks.
2. During the traction process, the trailer belt extends to the maximum stroke, and the elastic energy is fully gathered, producing a short and strong repelling effect. This resiliency, coupled with the car's traction, will work together on the trapped vehicle to make the structure easier and more efficient.
