In this paper are summarized the results of measurements of the driving characteristics of fire-fighting vehicles during the braking from high speeds. Two water tender vehicles manufactured by TATRA, used by the Fire Rescue Service of the Czech Republic, were compared. The tested vehicles differ in their braking systems. In the study are monitored the braking distance and deceleration, which were compared with previous tests focusing on tire type, test track surface, and weather conditions. When braking from a speed of 80 km/h, the worst results of the braking distance were recorded for SCANIA of 64 m and TATRA TerrNo1 (9T5 2243), of 73 m. These vehicles were equipped with drum brakes. In the case of the SCANIA vehicle, the cause was the heating of the drum brakes. For the TATRA TerrNo1, the reduced braking efficiency was likely due to the brake wear and thermal effects on the drum brakes.

Keywords: firefighting vehicle, braking distance, longitudinal acceleration
Grants and funding:

This paper was created within the research on the projects of specific research ”Verification of driving characteristics of firefighting water tenders“ (project registration number SP2021/58), but primarily with the support of the management of the Fire Rescue Service of the Moravian-Silesian Region. The author team of this paper would like to express their gratitude to all collaborators, firefighters, and their commanders, especially from the fire stations in Novy Jicin and Koprivnice.
