The jack mentioned here, not the original car comes with a jack used to change the spare tire.
Although the original car comes with a jack and off-road rescue special jack structure is not different, but because the original car with the standard jack is often not much travel, in the replacement of a larger tire is likely to be unable to jack the vehicle off the ground.
And in the event of a trap, the long stroke of the jack can also be the whole car directly out of the obstacle course.
The current mainstream products are divided into mechanical and hydraulic structure, of which the mechanical structure of the monkey climbing bar is stable and reliable, while the hydraulic structure in the operation is more simplified. However, no matter which one is used, it should be used with the base, thus preventing it from falling into the soft ground.
Don't look at the name of the equipment called anti-sand board, but in fact it can be used under sand, mud, snow and other roads.
Especially for some people who do not have a winch, the sand board and shovel is the only thing to rely on after a trap occurs outdoors. After all, the essence of the vehicle is trapped because the tires lost traction, the sand board can be the root of the problem.
The actual effectiveness of sand guards depends on providing enough friction, both with the tires and with the ground.
Not only that, but changes in temperature can also lead to changes in the performance of the anti-sand plate, which is very much a test of the material used in the product, which has to be as soft as possible at low temperatures while still being wear resistant.
Before using the sandproof plate for extrication, the chassis, bridge package and other easy to be dragged position clean, in the insertion of the sandproof plate to pay attention to the angle, should be as much as possible to let the sandproof plate and tire contact. Once you find that the vehicle can not get out of trouble, you should release the brake in time, so as not to aggravate the degree of wear and tear of the sandproof plate.
Overall, as long as you follow the above guidelines, you will be able to meet the rescue in 99% of cases successfully completed. However, considering the huge size of some of the equipment, you may want to install a modular luggage frame for your car, both to improve the value and to meet the actual needs.
