Fire fighting truck, also known as fire truck, refers to a vehicle designed and manufactured to suit firefighters' use, equipped with various types of firefighting equipment or extinguishing agents, and used by firefighting forces for firefighting, auxiliary firefighting, or firefighting rescue, including China Most of the national fire departments will also use it for other emergency rescue purposes. The fire fighting truck can transport firefighters to the disaster site and provide them with a variety of tools for disaster relief tasks.

The size of the fire fighting truck water tank directly affects the fire fighting ability of the fire fighting truck, which is mainly determined by the power of the fire fighting truck. According to the material, the water tank can be divided into soft water tank (made of canvas or rubber) and rigid water tank (made of metal material). The soft water tank is light in weight and occupies a small space in the non-working state. Stability, and the characteristics of rigid water tanks are just the opposite of soft water tanks.
1.The overall streamlined design of the fire fighting truck, the appearance is novel, the water pump adopts the sandwich power take-off method, achieves travel, fire fighting synchronous action, economical, practical, maneuverable and flexible, it is a new generation of substitute products of the same type of fire truck. This vehicle is suitable for small and medium-sized cities, fire brigades, fire brigades, township fire stations and full-time fire brigades of common mining enterprises to extinguish general material fires.
2.The fire fighting performance of forest fire fighting truck Water is the most effective fire extinguishing agent. Water fire fighting is the preferred method of forest fire fighting in most countries today. Therefore, water tanks and fire pumps use water fire extinguishing devices as the main fire extinguishing system. Required equipment.
The size of the water tank of the forest fire fighting truck directly affects the fire fighting ability of the fire truck, which is mainly determined by the power of the fire truck. According to the material, the water tank can be divided into soft water tank (made of canvas or rubber) and rigid water tank (made of metal material). The soft water tank is light in weight and occupies a small space in non-working state, but the disadvantage is that it increases when the fire fighting truck is driving. The instability of the rigid water tank is just the opposite of that of the soft water tank. In addition to the fire fighting function, it is necessary to carry firefighters, fire fighting equipment and fire fighting water to the fire scene. Therefore, the carrying capacity of the fire fighting truck is an important factor affecting the fire fighting ability of the forest fire truck.
Cross-country performance means that the size of the fire fighting truck water tank directly affects the fire fighting ability of the fire fighting truck, which is mainly determined by the power of the fire fighting truck. The factors that affect the off-road performance of fire fighting truck mainly include dynamic performance, drive mode, chassis rigidity, ground clearance, tires, and the forward and departure angles of the vehicle.
The climbing ability is generally expressed by the maximum climbing degree, which is an important indicator for considering the off-road ability of off-road vehicles. The primary factor that affects the maximum gradeability is the dynamic performance of the car, because the fire fighting truck has to overcome a component of its own gravity along the gradient direction during the climbing process, and at the same time, the grip ability of the fire fighting truck’s tires must be able to satisfy the car’s upward movement. If the power is not enough or the tires are slipping, climbing will be impossible; secondly, the forward angle and departure angle of the car are also important factors that restrict the maximum gradeability. The soft ground and swamp passability of fire trucks are also important indicators to characterize their off-road performance.
A fire fighting truck needs to go through woodland to go to the fire site. Because of the bushes and weeds in the forest, the road conditions are poor or there is no road at all, it will be very difficult for the fire fighting truck to drive in the forest. In order to eliminate these obstacles to driving, it is necessary to install a bush clearing device on the front of the fire fighting truck. For example, the French National Forest Service has developed a chain flail-type shrub remover with a diameter of 1.26m. This device can be installed at the front of the vehicle by clearing the bushes in the lower layer of the forest, helping fire trucks to open fire-fighting roads or cut off the line of fire. It is an effective tool for forest fire fighting and the safety of disaster relief personnel.
Because shrubs and weeds on the forest surface are easier to burn, and most of the forest fires spread from the ground, cutting off the surface fire is the key to preventing forest fires from expanding. Install fire fighting plows on the fire fighting truck, plow the fire belt horizontally in the forward direction of the forest fire through the plow body, and make the turned-up soil fill up and cover the ground surface with combustible materials, which can effectively prevent the fire source Continue to spread and put out the fire as soon as possible.
Good communication function is a necessary function for fire fighting truck to be able to carry out effective operations in harsh environments. Fully use the fast-developing modern communication technology and equip the fire fighting truck with advanced communication equipment, which can closely strengthen the horizontal and vertical connections, so that the command center can fully understand the fire scene information, coordinate the overall operations of the rescue points, and effectively improve the efficiency of fire fighting.
