The intelligent lithium battery drilling machine adopts patented constant power technology to ensure the motor's control function on torque output. With 3KW ultra-high power, constant speed drilling can be easily achieved. It not only ensures fast drilling, but also prevents the operator from overexerting and damaging the drill bit and motor. The LED speed alarm light can remind the operator in real time whether the feed force is reasonable.
If there is a problem with the battery or motor, the intelligent overload and overheating protection system will automatically cut off the power supply. Ensure the dual safety of the machine and the operator.

Nzg-31II internal combustion rail drilling machine is a special machine suitable for drilling rail fishplate bolt holes in railway engineering and construction departments. It is suitable for drilling holes in P65 and P75 rails. It uses a small gasoline engine as the power, which is decelerated by a special reducer to drive the drill rod to rotate. The handle drives the gear and rack to achieve feeding, and the worm gear mechanism is clamped. A drill rod bracket is provided to ensure the accuracy of the drilling direction and extend the service life of the drill bit, and it is equipped with a special hollow drill bit. Therefore, this machine has the advantages of novel structure, small size, light weight, high efficiency, convenient clamping, and accurate drilling.

The point rail is an important part of the switch. The train is guided to the main line or the side line by the movement of the point rail. As railway transportation continues to develop towards high speed and heavy load, the wear and scrapping of the switch point rails has accelerated, especially the side wear of the point rails is more serious. It is necessary to measure the wear state of the point rails frequently and give maintenance suggestions for grinding or replacing the point rails. There are many types of point rails. Measuring different side wear, vertical wear, and reduction values of point rails requires corresponding detection rulers of different types. There is no universal measuring tool. This product can be used to measure the side wear, vertical wear, and reduction values of all types of point rails.

Because the main part of the wheel tread is a slope of 1:40, in order to make the top surface of the rail evenly stressed under the load of the wheel with a tapered tread, the rail should not be laid vertically on a straight line, but should be tilted inward appropriately. This inclination of the rail is called the rail bottom slope. The rail bottom slope measuring instrument is a measuring instrument used to measure the rail bottom slope and angle of the rail. This product has a fast measurement speed and is easy to use. It can be used during the day and at night. It is an ideal measurement tool for engineering and construction departments.

The sliding rail wear measuring ruler is used to measure the vertical wear value, lateral wear value and point rail reduction value of the rail. It adopts digital reading and reasonable design, making it light in weight, easy to operate and intuitive in reading.
