Four-axle vehicle with transformable running gear is researched in the article. Running gear is implemented as lift axles. Its correspondence with possible turning modes is explored. Main attention is drawn to the turning mode with desynchronization of angular velocities of different axle wheels rotation – front axle slip and rear axle slide turning mode. The calculations done by means of simulation shows such mode allows to reduce turning diameter as much as possible, until the vehicle will turn around the central point of rear axle. The application of this turning mode is reasonable in conditions of limited space.

Four-axle vehicle with transformable running gear is researched in the article. Running gear is implemented as lift axles. Required design features are explored. Main attention is drawn to the engineering upgrade of transfer case and brake units. The design layout calculations, as well as strength analysis and kinematical designing the changes are close to modernization process and there is no necessity to use any completely new unit. The application of this concept is reasonable in conditions of high requirements to maneuverability together with long and middle distance haulage.

Issues of people rescue from the crashed car body are researched in the article. It is described the method of hydroabrasive metal cutting. Mobile vehicle with hydroabrasive cutting tool based on a wheeled chassis was proposed to deal with the consequences of car accinents. The Idea application is reasonable for cars as well as for bullet-proof, military and railroad vehicles.
