Scale test truck (hereinafter - truck) is a part of equipment of scale test cars of VPV-А-300, VPV-640, VPV-188, VPV-0172 models and is designed for movement of balance weights of parallelepiped shape of 2000 kg weight (working standards of the 4th degree) and ensuring of verification or calibration of wagon scales in the complete with balance weights.
The truck consists of the frame, mounted on two wheel pairs, which are driven by two electric motors and provide movement of the truck on the rails.
