FIELD: railway transport. SUBSTANCE: rail freight car has freight platform body, two wheelset, two two-axle running mechanisms or two bogies. Shock is absorbed by leaf springs suspended on spring with loops. Guide of wheelsets of two-axle running mechanisms under freight platform body, or guides of wheelsets in bogie frames provide vertical movement and limited horizontal turning of wheelsets relative to freight platform body or bogie frame, or two-axle running mechanism relative to platform body. Lifting member is placed between each spring loop and corresponding spring support of freight platform body or bogie frame. Loading bridge is lifted relative to wheelsets or bridge with frame is lifted relative to wheelsets by means of this member. EFFECT: enlarged operating capabilities. |
