The Present Fire Trucks

Old and used fire trucks or let us say antique fire trucks are now being replaced by a more developed and innovated kinds of fire trucks which makes the life of firefighters easier and with less hassle.
A modern fire engine is usually a multi-purpose vehicle transmitting aced individuals and apparatus for a wide range of fire-fighting and rescue undertakings. As a result, most fire engines carry equipment such as portable stairways, pike poles, axes and cutting equipment, Halligan bars, fire extinguishers, ventilating equipment, floodlights, hose ramps, self-contained breathing apparatus, and general tools. Profuse fire appliances are based on standard truck or lorry models with sturdy suspensions, brakes, tires, alternator, transmission and cooling systems; audible and visual warnings such as sirens, horns, and flashing lights, and a two way radio.

Our fire trucks these days are packed with different tools carrying personnel and tools for a large range of fire-fighting and rescue tasks. Therefore, most pumpers also carry equipment such as ladders, pike poles, axes and Hydraulic rescue tools, Halligans, fire extinguishers, ventilating equipment, floodlights, hose ramps, breathing apparatus and general tools. In several places, a ladder truck may carry all of these tools and more.

Fire equipment are called in different names, the most common being fire engine, appliance, apparatus, or a pumper. The Turntable Ladder, sometimes abbreviated to simply TL is the best-known form of specialized fire apparatus, and is used to gain access to fires occurring at height, where typical ladders that might not reach on desired location.

The name is derived from the fact that the large ladder is mounted on a turntable on the back of a truck or lorry, authorizing it to rotate around a secured base, which in turn permits a greater ladder length to be gained. In order to maximize its length, the ladder is telescopic. Modern TLs are hydraulic or pneumatic in operation. A ladder also can be mounted behind the cab. This is called "mid ship". This kind of set-up keeps a shorter wheel base for the vehicle, and also can be more stable in some conditions.

While the traditional characteristic of a fire truck was a lack of water pumping or storage, lots of modern TLs are packed with a water pumping function, and may have a pre-piped waterway running the length of the ladder, to let the firefighters at the top to jet a stream of water. Due to some occurrences, there may also be a monitor at the top of the ladder for ease of use. Some fire engines secure a trackway where the hose is attached to it, and forbidding it from falling to the ground.

Some TLs may have a basket or platform mounted at the top of the ladder, as on a hydraulic platform, and these are called Tower Ladders. These can provide a secure place for a firefighter to operate equipment from, and allow multiple people to be carried.
