FIELD: special purpose vehicles.

SUBSTANCE: invention relates to vehicles for the transportation of long loads in the logging industry, mainly to log trucks. The vehicle contains a tracked self-propelled chassis (1) with a skeleton (2), on which a manipulator crane (3) with an arm and a lifting body (4) is placed, a cargo platform (5) with a frame (6). The front part of the cargo platform (5) is equipped with a traction device (7), which is connected to the skeleton (2) of the self-propelled chassis (1) through a frame (8) pivoting in the vertical plane, equipped with a hydraulic drive and fixed pivotally on the skeleton (2). The hydraulic drive of the rotary frame (8) is made in the form of one or more hydraulic cylinders (9) installed in parallel, some ends of which are fixed to the skeleton (2) of the self-propelled chassis (1), and the others are attached to the rotary frame (8). The rear part of the cargo platform (5) is supported by wheeled trolleys (10). The frame (6) of the cargo platform (5) is equipped with rollers (11) installed perpendicular to the longitudinal axis of the frame (6) at different heights so that the plane passing tangentially to the rolling surfaces of all the rollers is inclined to the horizontal line at an angle α, the top of which is oriented to the traction device. The value of the angle of inclination α is 10-15°.

EFFECT: invention improves the performance of the vehicle.
