High Quality Smart Rail Tamping Machine Unit

YD-22III Smart rail tamping machine unit is a renewal product developed by our factory with new material and new technology. It has collected the tamping experience of users at home and abroad. It can do tamping works not only on the ballasted track of concrete sleeper type II and III in China, but also on various kinds of concrete sleepers and steel sleepers in foreign countries. This machine is suitable for tamping operation of different types of rails and concrete sleeper line after large and medium repair and sieving operations, and also suitable for tamping operation of ballast on newly built track bed. The equipment has superior performance, reasonable structure, safety and reliability, and high working efficiency. It fully meets the needs of railway ballast tamping operation.

Basic Structure and Working Principle

Working Principle: YD-22III smart rail tamping machine unit is powered by gasoline engine and drives oil pump and vibration shaft respectively through triangular belt. The eccentric body rotating at high speed with the vibration shaft produces exciting force due to centrifugal force, and the high-pressure oil from the oil pump enters the lifting cylinder and clamping cylinder through the reversing valve, thus driving the executing parts, realizing the functions of clamping rails, inserting down, clamping and other tamping operations.

Operating mode can choose remote control operation, and also can use manual move reversing multi-way valves to carry out manual control operation.
