Steel rail, also called rail track, steel track, is the main component of railway track. Its function is to guide the wheels of the locomotive, bear the great pressure of the wheel, and keep the stability of railway transportation. The rail must provide continuous, smooth and minimum rolling surfaces for the wheels. In electrified railway or automatic block section, rail can also be used as an orbital circuit.
The steel rail in china are divided into Crane rail, Heavy rail and light rail.Â
Light rail is divided into GB and the ministry standard (YB metallurgical standard). There are 8kg, 12kg, 15kg, 18kg, 22kg, 24kg, 30kg.Â
The light rail is mainly used for the laying of temporary transportation lines and light locomotive lines for forest areas, mining areas, factories and construction sites.
It was 18th,July,2013 when I begun my career in Zhengzhou-Europe International Shuttle Train project and also the project came into operation. I was very professional and experienced in the whole procedure of train transportation industry and we will be at your service with lower price and higher professionality.Also We can provide "door to door"service in European countries.
This machine is the special device to exert rail vibration on seamless rail to relieve the rail stress. It is pushed forward by a single operator.
Product features
It is equipped with two pairs of knocking hammers, which knock the inside and outside of two steel heads with same force. It can knock each rail for 48 times per minute.
It also contains a startup engine which drives the knocking hammer control rod via a v-belt drive reducer. The knocking hammer is equipped with plastic pads to prevent the formation of knocking marks on the rail or damage on rail. The entire system is mounted on a ultra-light cast with 4 cast irons and insulation wheels.
The knocking is start by the hand clutch mounted near the engine.
The complete machine can be on-track through 4 lifting eyes by the crane and also by four persons.
The knocking hammer is covered with a metal mesh to protect the operator and worker safety. In case of emergency, it can activate the emergency switch to shut down the machine.
