FIELD: mechanics.
SUBSTANCE: invention relates to railway transport. Swing suspension of trolley includes tractions suspended on rollers, which rest upon supports by circular grooves. The supports are made with thrusts having tapered surfaces from the side of tractions. Each thrust is implemented with a hollow for accommodating inner roller rim and thrust surfaces in the upper part, which are located so that they can contact with traction to limits its displacement along roller.
EFFECT: reduced dimensions of roller and increased effectiveness of thrusts.
