Abstract The analysis of emergency rescue equipment usage on the territory of the Republic of Belarus made it possible to identify that the main technical unit involved into emergency situations is a fire truck tank. One of the main reasons for its repair and withdrawal from operational status is tank leakage that occurs due to peculiarities of equipment usage. As a result of a complex of studies, the recommendations for the modernization of a standard tank with 5 m3 volume of a fire truck were developed on the MAZ-5337 chassis. The stress state of a standard and modernized tank of a fire engine was investigated by the strain-gauge method under various operating modes of movement.
Keywords fire truck, tank, modernization, mechanical stress, resistance-strain sensor, safety factor, welded joint, stiffener
