Chains for cars used for driving on snow can be purchased in stores. It’s a little harder to get auxiliary tools for driving over deep mud, which often happens when off-road cars drive through a forest, thicket, or swamp. When the bottom of the car touches the ground then the chains no longer help.
This problem can be easily solved with the help of two chains at least 5 meters long, about a hundred medium-sized nails, and a little work.
The most important thing is that there is a bush nearby with straight branches 5-10 centimeters thick and 3-4 meters long.
To make a wooden base that is laid on the ground, in a place where there is deep mud, it is necessary to cut the required number of thicker flat branches, or thinner trunks. These thin trunks are placed on the ground, next to each other, and one chain is placed on each side of the trunk, which can be seen above in Fig. 1. The distance between individual trunks depends on the diameter of the car wheels. With smaller wheels, the trunks should be thinner and the distance between them smaller. With larger wheels, the trunks should be thicker, and the distance between them may be greater. Then the chains are nailed to the trunks on both sides. This gives a ladder laid on the ground that needs to be placed in front of the car at the point where it is necessary to cross the mud. When the car crosses such ladders, it is possible to roll them into a ball pic 2. and put them on the car so that the ladder can be used at a new place with deep mud.
If the driver expects a large number of places with deep mud before setting off through a forest, thicket or swamp, he can make such ladders from solid wooden planks in advance before setting off, which he can put on a car or a trailer. Instead of chains, such boards could be connected with solid textiles along their entire length and width, so that mud could not penetrate upwards between the boards and settle to the bottom and sides of the car.
In professional production, such mud ladders could be made of solid, elastic, thin metal pipes or rods connected by wear-resistant solid textiles. Several such ladders with thin tubes could be wrapped like a carpet and kept permanently on the roof of off-road vehicles. Trucks that sometimes have to go through deep mud or snow could keep such a wrapped “carpet” with built-in pipes or rods under the trailer near tool accessories.
