The scope of application

NLQ-45 type concrete sleeper bolt drilling machine is suitable for the drilling of various types of concrete sleeper bolts under the condition of blocking line. The principle of the nesting knife can be used to drill holes in any position on the concrete sleeper. Re-anchor the sleeper bolts in the drilled hole.

The machine uses a split structure, the host and the fixed seat can be separated with a fixed seat drilling operations, but also direct use of the host alone drilling operations. With high efficiency, wide application, the next road speed, high security features, reducing the labor intensity of workers, is the line laying and maintenance of the necessary tools.


It's suitable for various concrete tie dowel drilling & pulling with the track being occupied. According to the principle of trepanning tool, it can drill & pull the bolt anchored on concrete tie without damaging tie. And the bolt can be anchored again in the same hole being drilled.

It's main frame and fixture is divided with feature of moving away from the track quickly. While working, if it's necessary to move the machine away from the track, just loosen the joint bolt between the main frame and the fixture. Then only move the main frame to a safe spot and let the fixture remain still. After the traffic is over, install the main frame to work again. In this way, the working efficiency is increased and the labor intensity is reduced. It's an indispensable tool used in track relaying and repairing operation.
