The pneumatic railway tamping machine is powered by compressed air and is relatively light. It is suitable for tamping medium-sized casting sand molds, and can also be used for concrete and brick blanks.

When clamping the track, whether the railway tamping machine has serious road lift phenomenon, it can be judged whether the working oil pressure is too high.

The purpose of repairing and maintaining steel rail is to ensure the geometric dimensions of the steel rail. During the operation of the train, the impact force on the steel rail is very large, and it is easy to cause the deformation of the steel rail. Therefore, if you want to enhance the maintenance and maintenance of the steel rail, it is necessary to strengthen the adjustment of the geometric size of the steel rail.

Regular inspection of the steel rail is the basis of its maintenance. Any plan for steel rail maintenance is specified based on the results of regular inspection. The inspection of steel rail shall be consistent with the actual situation on site, and the scheme shall be careful and reasonably arranged to complete the early detection and early report of steel rail problems.

The railway tamping machine is powered by a high-performance, high-quality imported gasoline engine, with stable output power, low fuel consumption and low noise. The railway tamping machine can also be powered by an electric motor or a diesel engine according to user needs.

The rail track lifting and lining machine is suitable for lifting rails, bridges or other heavy objects when building railways; it is also suitable for industrial and mining enterprises, transportation, ports and other enterprises to transport, install, adjust equipment and hoist and transport various heavy objects as lifting tools . The following are the six safety precautions for the rail track lifting and lining machine, let us understand it together:

The peeling near the fillet on the working edge of the steel rail head is mainly caused by the following three reasons: the peeling is caused by the longitudinal fatigue crack caused by the inclusion or the contact shear stress; the shear stress alternating cycle caused by the guide wheel on the curved outer steel rail promotes the rail Fatigue of the outer steel rail head leads to peeling; poor maintenance of wheels and steel rail accelerates the development of peeling. Usually peeling will cause stress concentration in the notch area and affect the ride comfort, increase the dynamic impact, and promote the generation and development of cracks in the notch area. The existence of the notch area will also hinder the development of metal plastic deformation and reduce the plastic index of the steel rail.

The formation of steel rail contact fatigue damage can be roughly divided into three stages: the first stage is the change of the shape of the rail tread, such as unevenness of the rail tread, saddle wear at the weld, these unevenness will increase the impact of the wheel on the steel rail.
