The length of each hose is generally 20 meters. Some climbing ladder cars will be equipped with 30m and 50m water hose. The length of fire hose is 355mm.

For heavy-duty vehicles, it is mainly water cannon to put out the fire, with long range and large flow. The fire fighting depends on the actual situation, not on the number of water hose, because the longer the water hose is connected, the greater the pressure loss and the smaller the fire fighting efficiency. In terms of configuration, heavy-duty vehicles are generally equipped with 15-20 discs of 64mm water hose and about 10 discs of 80mm water hose, and a large part of space should be left to place some simple water hose First aid equipment, generally also set aside 7-8 disc to do motorized hose.

Extended information:

The fire hose can be divided into lining fire hose and leakage fire hose. The lined fire hose includes rubber fire hose, TPU fire hose, polyester rubber hose and hemp plastic hose. According to the working pressure, it can be divided into four categories: 0.8MPa, 1.0MPa, 1.3mpa and 1.6Mpa. According to the diameter, it can be divided into four categories: 50 mm, 65 mm, 80 mm, 75 mm and 90 mm. It can be divided into plain water belt and twill water belt.

When laying the water belt, avoid sharp objects and various oils. When laying the water belt vertically to a high place, use the water belt hook. When laying the water belt through the traffic main road, the water belt bridge should be padded. When passing the railway, the water belt should pass under the track, so as to avoid the water belt being crushed by the wheel and intermittent water supply.

Fire hose accessories include hose cloth, hose hook, hose bridge, interface, water distributor, etc.

① The hose cloth is used to wrap the fire hose leakage, which is one of the necessary accessories on the fire truck. It is composed of canvas belt, metal clamp and other parts.

② The hose hook is a tool to hang the fire hose. In the fire fighting, when the hose is vertically laid to the high place, the hose hook is used to hang the hose on the ladder or other objects, which can not only reduce the falling force of the hose, but also facilitate the water gunner to control the water gun to fire. The hose hook is composed of canvas belt, metal hook and half ring.

③ The water belt bridge is used to protect the water belt from affecting the normal driving of vehicles when it is laid horizontally on the main road. It has the characteristics of high strength, compression resistance and durability, and easy to clean up.
