Mobile hydroelectric power station

It is hard to tell that the inner makings of this hydraulic platform even surpass its imposing appearance. Yet this is exactly the case with the ULF-TMB 4000 of the plant fire department for the Schwechat industrial park. The B42FA is a combination of universal firefighting vehicle and telescopic mast platform with 4,000 liters of on-board extinguishing agent. At first glance, it looks purely like an aerial rescue device with a four-part main telescopic boom and one-piece cage boom that extends to a height of 42 m fully erected and has a horizontal reach of 22 m, in both instances with the cage at full capacity. But once the front equipment compartment is opened, a second glance reveals a power generator for firefighting equipment that can handle even the high fire loads of refineries, tank farms, and petrochemical industrial plants.

Extinguishing from a Height of 42 m

The extinguishing technology of the B42FA essentially consists of a powerful firefighting pump and an industrial foam proportioning system with the same performance. The built-in pump can convey a total of 8,000 liters per minute and is thus able to supply both turrets – one on the roof of the pump house and the other on the cage railing – with 4,000 l/min of extinguishing agent. Water and foam can be discharged via the turrets, the cage turret can also be controlled remotely (100 m range), and all of the firefighting equipment can be automated for continuous use. For hand-operated extinguishing, the vehicle is equipped with nine discharge outlets, four on each side of the vehicle and one on the right-hand front of the cage, as well as plenty of hose materials and fittings.

Efficient First Attack

Impressive water pipes lead through the superstructure: the water to the cage is guided through its own rotary feedthrough in the pivot mounting and a telescopic pipe along the main boom. Water is supplied via the hydrant network of the industrial park. The suction inlets are located in the rear of the vehicle and on the left and right sides of the front equipment compartments. The 4,000-liter foam tank is mounted behind the pump house. The on-board capacity is usually sufficient to carry out a massive first attack and lasts until backup arrives.

Modern Assistants

In addition to aerial rescue and extinguishing technology, the industrial emergency vehicle also impresses with its modern assistance systems. These include a Birdview system with four cameras, a reversing camera with acoustic warning, ultrasonic distance sensors that warn the driver of fixed or moving obstacles in the vicinity of the vehicle, and the service4fire remote diagnosis system, which records, analyzes, and documents all operating and consumer data.
