Abstract: In an operating method for an emergency vehicle, especially a fire truck, having a vehicle body, a drive unit having a drive motor and a motor controller, front-wheel and rear-wheel pairs, an emergency aggregate, a signaling device, an illuminating device, and a mode-of-operation controller having a mode-of-operation selector switch having selectable operation modes and a memory with saved operating-data sets, by a sequence controller of the mode-of-operation controller, selecting a first operation mode corresponding to an emergency trip transmits from the memory to the target systems, and activates, first operating-data data sets. Selecting a second operation mode corresponding to an emergency mode deactivates the transmitted first operation mode operating-data sets, and transmits from the memory to the target systems, and activates, second operating-data sets.

Abstract: The invention relates to an emergency vehicle (1) designed as a heavy truck, comprising a vehicle body (2) having an underbody assembly (9), a roof assembly (10) and at least one longitudinal wall (11, 12). Furthermore, a central longitudinal beam (8) is provided that is disposed in a manner extending in vehicle longitudinal direction. The central longitudinal beam (8) is joined directly and securely to the vehicle body (2), wherein it forms an integral constituent of the underbody assembly (9) of the vehicle body (2).

Abstract: The invention relates to a vehicle (1) having a vehicle body (2) and a loading arrangement (5), which comprises a first loading platform (6) and a lifting unit (7) having a guide system (8) and an actuating mechanism (9). The first loading platform (6) is liftable and lowerable by means of the actuating mechanism (9). The loading arrangement (5) comprises a bearing unit (14), which defines a pivot axis (16), as well as a pivoting unit (15). The bearing unit (14) is disposed on the guide system (8). The first loading platform (6) is mounted on the bearing unit (14) in a manner pivotable about its pivot axis (16) and is in driving communication with the pivoting unit (15). By means of the pivoting unit (15), the first loading platform (6), in its relative position with respect to the guide system (8), is adjustable around the pivot axis (16) of the bearing unit (14).

Abstract: The invention relates to an emergency vehicle (1), especially fire truck, comprising: a vehicle body (2); at least two wheel pairs (3) having respectively at least two wheels (6), which are disposed on the vehicle body (2); an accumulator (10) for storage of electrical energy; a secondary energy unit (7) for conversion of an energy stored in a fuel into electrical energy; at least one electric motor (11). The secondary energy unit (7) is disposed on a carrier frame (14), wherein the carrier frame (14) is received in modular and detachable manner on the vehicle body (2).

Abstract: The invention relates to an apparatus for the one-dimensional, highly precise measurement of extension at the surfaces of hot specimens. The working range extends from normal temperature to about 1800.degree. C., but measurements are also possible up to 2300.degree. C. With respect to atmospheric pressure, the application range extends from vacuum up to pressures of several bar. The high-temperature extensometer in accordance with the invention is distinctly more cost-effective than previous extensometers for hot test specimens, despite its considerably larger measurement range.
