FIELD: transportation.
SUBSTANCE: lifting linkage includes a frame, a boom arm, an upper lever, a lower lever, and a hydraulic drive. The boom arm is made with the possibility to be hinged with a working tool and has a surface that defines the longitudinal axis. The first end of the upper lever is hingedly connected to the frame, and the second end is hingedly connected to the boom arm. The first lever of the lower lever is hingedly connected to the frame, and the second end is hingedly connected to the boom arm. The hydraulic drive has a stem hingedly connected to the boom arm, and moves between the retracted position and the extended position. The upper lever, the lower lever, and the hydraulic drive are spaced from the longitudinal axis.
EFFECT: improved operational reliability.
