The optimum dimensions of the structural elements components were identified. The recommendations for the structural addition of fire truck’s tanks AC-5.0-50/4 on the basis of the chassis MAZ-5337 were developed.</p><p><em>Application field of research.</em> The presented results of the research were obtained in the field of strength properties of containers for the transportation of liquids and can be used in the repair and upgrading works of the relevant constructions.</p><p><em>Conclusions.</em> The integration and practical complex implementation of the recommendations has improved the operational reliability of the fire truck’s tank AC-5.0-50/4 on the basis of the chassis MAZ-5337 by more than 30 %, thereby increasing its overhaul period.</p> ER -
