Smart Remote Control Rail Tamping Machine Unit

1. Scope of Application

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.

The advantages of the Smart Rail Tamping Unit are as follows:

1. The chassis of tamping unit is equipped with walking device and electronic control device (electric engine and remote control will control each function of the equipment). The equipment realizes the characteristics of automatic walking ad remote control, which greatly improves the working efficiency and comfort, it also can reduce the labor intensity.

2. The tamping machine retains the original manual reversing valve, which ensures the safety and stability of the operation. And also, it has the front and rear lights which can provide better lighting when working at night.

3. 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.
