Telescopic mast (fire brigade)

from Wikipedia, the free encyclopedia

A telescopic mast (TM) or a telescopic mast vehicle (TMF) is an aerial rescue vehicle used by the fire service . The term telescopic ladder with basket (TLK) is purely a manufacturer's name.

The telescopic mast vehicle is an aerial work platform (HAB) and has an aerial rescue boom according to DIN EN 1777 . A number after the abbreviation indicates the rescue height in meters (e.g. TM 32 stands for a rescue height of 32 meters) and another, if applicable, the maximum possible radius .

Human rescue

Telescopic masts enable people to be rescued from particularly exposed locations that cannot be reached with conventional turntable ladders . The articulation parts that can be bent are particularly helpful here, with which obstacles can be avoided, so to speak, even in the smallest of spaces. Due to the larger rescue cage, rescuing overweight people is also easier with a telescopic mast than with a turntable ladder. The fact that an extended telescopic articulated mast fluctuates less than an extended turntable ladder makes working and rescue heights of more than 100 meters possible.

Fire fighting

Telescopic mast vehicles are also used to fight fires, especially in the event of larger fires . In this way, a larger or hard-to-reach area of ​​fire can be fought specifically from above. In addition, the mast (in contrast to most turntable ladders) has a permanently installed water pipe to the water / foam monitor on the work basket. The auxiliary and fire brigade loading varies, as these vehicles are mostly individual custom-made products.

Vehicle examples

Telescopic mast vehicles are available from various manufacturers in many variants. Examples:

  • The telescopic mast TM 50 of the company Metz Aerials and WUMAG elevant on a MAN -Fahrgestell type MAN TGA  26.414 is in the Berlin fire brigade on duty. The work basket carries a load of 400 kilograms and reaches a working height of 50 meters. In addition, connections for breathing air are installed in the basket so that up to three people can be supplied from the floor via an air line. So that several people can be evacuated quickly, a 50-meter-long rescue hose can be attached to the basket , through which two to three people per minute can "slide" safely. The vehicle has a gross vehicle weight of 31,760 kilograms.
  • The TMF 53 telescopic mast vehicle used by the Hamburg fire brigade on a four-axle MAN chassis of the type MAN 26.413 FDLC with a steered trailing axle is extremely manoeuvrable and reaches a maximum height of 53 meters. Despite the great height, the mast (in contrast to the turntable ladder) only sways minimally. The vehicle made by Ziegler and Bronto-Skylift has a permissible total weight of 35 tons.
  • The telescopic mast TM 52 (also by Ziegler and Bronto-Skylift) of the main fire station of the Vattenfall plant fire department located in the industrial park Schwarze Pump is based on an all-terrain, four-axle Scania chassis (P-series) and reaches a height of 52 meters. This means that the vehicle can be used both in the power plants and in the open-cast mines in the Lusatian lignite mining area .
  • The TM 32 telescopic mast of the Walldorf Volunteer Fire Brigade was installed by Ziegler and Bronto-Skylift on a Mercedes-Benz Econic chassis. The basket carries a load of 500 kilograms and reaches a working height of 32 meters. The vehicle is from 2014 and has a gross vehicle weight of 18 tons.
  • The ALP 375 telescopic mast of the Hanau fire brigade is built by Iveco Magirus on a three-axle MAN TGA 26.360 chassis. The mast reaches a working height of 37 m with a cage payload of 400 kg. A monitor mounted on the basket delivers 3600 l / min and is equipped with a camera and remote control.
