Design specificity of Eams-z self-propelled wagon

Abstract

Self-propelled wagon Eams-Z inteded for bulk material transportation provides enhancement in railway infrastructure construction and maintenance. Its main advantage is possibility of manipulation along tracks and construction material discharging without use of locomotive. Thus this car saves energy, human resources, and shortens the time of transportation and unloading. The car has two crates with the possibility of side and frontal inclining using hydraulic cylinders. These cylinders provide controlled and precise unloading of cargo on 3 sides without need of any extra man or machine power. Power pack, consisting of Iveco engine, hydro transmission and two small wheels without flange is positioned in the middle of the car between the bogies. In the self-propelled regime wheels lower down to rails providing traction force needed for wagon manipulation. This car type requires special attention during design and calculations in order to achieve safe manipulation in all regimes.
