FIELD: transportation.

SUBSTANCE: towing-loading device to a trailer includes a swing car frame, to the bottom part of which, in the longitudinal direction, a thrust is fixed rigidly in the center, and a towbar is articulated to the front one. To the opposite end of the towbar a coupling is rigidly fixed, where, with the possibility of longitudinal displacement, a bracket is placed, the front end of which is rigidly connected to a pull ring. To the coupling, a beam placed under the swing car frame of the trailer, is articulated. The rear beam end by means of a connection link is hingedly connected to the middle of the rear part of the trailer swing car frame. A pendulum is articulated to the beam in its middle part with the possibility of longitudinal movement. The pendulum has the shape of an isosceles triangle, the vertex of which is hingedly connected to the beam, and the base has two rollers at its ends, which contact the thrust.

EFFECT: increasing the load carrying capacity of a vehicle, reducing the slippage of driving tractor wheels, increasing the efficiency of a transport unit.
