The frame of the construction acts as double parallelogram. Namely parallelogram acting in vertical plane is formed by bearing beam 2 and connecting element 5 in cooperation with the plough 1 and fixing mount 6 on the vehicle, parallelogram acting in horisontal plane is formed by bearing beam 2 and turn cylinder 7 in cooperation with the plough 1 and fixing mount 6 on the vehicle. Support frame according to the invention differs in that due to the use of connecting element 5 the support frame maintains feature of traditional "parallelogram" of the snow ploughs, which assures that the raised plough in transport position remains parallel to the ground.
