What if the vehicle is broken on the road? I believe most people will call the towing service. The best way to put a vehicle on the road is to use a direct trailer, but how many people know what we need to watch out for when we are on a trailer? Now let's talk about those considerations in the towing service.

First of all, most of the default towing service now is to use nylon-made trailer ropes for trailers, because of the relatively high cost performance. However, Xiao Bian suggested that if conditions permit, we should use flatbed trailers instead of trailer ropes when selecting towing services. Because the cart can fully erect the vehicle and avoid long-time vehicles being dragged, it plays a role in protecting the vehicle. Flatbed trucks have become an indispensable tool for modern logistics transportation. Checking carts on the highway is very common. Although few people use the trailer service, if you want to protect the new car that you just bought, choosing a flatbed can greatly reduce the damage to the vehicle. If there is damage to the traditional system of the vehicle due to improper trailers, it is undoubtedly an increase in losses.

Ordinary vehicles under the conditions allow, Xiaobian recommend the use of flatbed trailers to better protect the vehicle, but the next Xiaobian said that this model is not allowed to use trailer rope trailers. I believe many people have heard that it is an automatic car. The automatic transmission is different from the manual transmission transmission. Even if it is hung in the neutral position, the internal brakes, clutches, etc. of the automatic transmission still have friction. This can cause the internal parts of the vehicle to become hot and increase the damage of the vehicle. Although using a tow rope trailer can cause damage to the vehicle's drive system, short-range towing can be chosen in situations where it is not easy. Put the car on the N block, release the handbrake, keep the speed at around 30, but do not avoid long distances.

After reading this article, I now know the tips in the trailer service. Do not choose the default trailer method like everyone else. Whether your car is an automatic car or not, it is best to choose a flatbed trailer and try to “protect” your car.
