Description

The present invention relates to an emergency escape device for a large vehicle, for example, for escaping a large vehicle such as a fire engine stacked on a snowy road.

  When a small vehicle such as a car is stuck on a snowy road, for example, when it gets into fresh snow, as an emergency measure, for example, slowly move the vehicle back and forth to tread the snow around the tire, and then It is possible to escape. At that time, it is important to remove or harden the surrounding snow with a shovel.

  If you cannot escape even after the above operation, put a board, cloth, chain, etc. between the tire and snow and start slowly. In the case of an FR vehicle, it is also an effective means to have several people get on the rear seat and increase the load of the drive wheels.

In heavy snowfall areas, sand boxes are prepared on the side of the road, and this sand is sprinkled on the outer periphery of the drive wheels to increase grip.
It is also effective to reduce the tire pressure and increase the tire contact area. If there are people nearby, it is also effective to ask the passengers or passers-by for help and push the vehicle.

  Also, if you get on a block of snow instead of slipping and you can't move, move slowly back and forth at first, solidify the snow, and then when the tire is floating, scrape the snow with a scoop Ground the tire.

  However, any of the above-described methods is a stack escape method for a small vehicle, and cannot be said to be an effective means for a large and heavy vehicle such as a fire engine.

Conventionally, as an escape device for a large vehicle, a device in which, for example, a spike pin is attached to an intersecting portion of an apparatus main body that is knitted by obliquely intersecting a string made of rubber or plastic is generally known. In addition, by laying under the driving wheels of a large vehicle stacked with the escape device configured as described above, the double tires are prevented from slipping and escaped.
