Description

Maneuverable sub-fire fighting equipment that can be loaded on fire trucks {MANEUVER TYPE SUB FIRE-FIGHTING APPARATUS}

The present invention relates to a maneuverable sub-fire fighting apparatus that can be loaded on a fire truck, and more particularly, can be loaded into a cargo hold of a fire truck, and can be loaded on a fire truck so that the maneuverability can be increased to enter a narrow place and to extinguish fire. It relates to a mobile sub-fire fighting apparatus.

Early fire extinguishing is the most important factor in reducing fire and property damage in case of fire.

It is no exaggeration to say that minimizing the loss of life or property damage from a fire actually depends on how quickly the fire truck arrives and rapidly evolves.

However, in reality, even if the fire truck arrives at the fire site quickly, it is often unfortunate that the fire truck is inaccessible even in front of the fire site due to various factors such as narrow alleys, parked vehicles, or road difficulties.

In order to solve this problem, various measures have been proposed, such as providing a space for parking a fire truck or emergency fire truck.

However, since disasters such as fires do not occur frequently on a daily basis, these regulations are not always kept well due to safety insensitivity and the convenience of neighboring residents.

In particular, it is difficult to make a separate fire road in the narrow alleys of old houses, and due to the improvement of living standards, it is difficult to leave the fire road always empty due to the lack of parking facilities due to the arrival of the first-vehicle vehicle era.

In view of the above, there may be mentioned, for example, a "mobile robot fire suppression system" (hereinafter, referred to in the prior art) of Patent No. 10-1400769.

The prior art is to carry out the fire fighting robot to be carried on the fire truck to operate the fire suppression, but because of adopting the endless track for the running of the fire robot, there was a problem that it is difficult to quickly put the fire site to drop the running speed.

In particular, in the prior art, since the communication with the fire robot is not performed smoothly due to external variables such as heat and high temperature of the fire site in the process of remotely controlling the fire robot, the firefighters arrive at the fire site and perform direct fire fighting work. You may have difficulty with rapid early evolution compared to performing.

Therefore, as described above, there is an urgent need for the development of a device or equipment capable of rapidly approaching the fire site without any limitations in narrow spaces and roads.
