FIELD: machine building.

SUBSTANCE: invention relates to earth-moving equipment, and more specifically to wheeled excavating machines. Wheeled excavating machine comprising a wheel chassis, on the frame of which a working equipment frame is fixed, comprising a blade soil thrower, configured to transport the developed soil to the dump, chain working tool for soil development, oil station, working equipment drive, chain working member lifting and lowering hydraulic cylinders, working equipment turning hydraulic cylinders in horizontal plane. Between the chassis and the working equipment frame there is an intermediate frame, in the lower part of which there is a caterpillar propulsor, which is symmetrical to the longitudinal axis of the machine, consisting of a bearing frame and a caterpillar chassis. Side reduction gears and hydraulic motors mounted on caterpillar propulsor frame are made with possibility to transmit power flow from oil station of wheel chassis.

EFFECT: technical result consists in increase traction-coupling characteristics of wheel-mounted excavating machine and reduction of load on running gear of wheel chassis.
