1,Overview

The removal of the mine anchor netting is quite complex and laborious. The conventional method involves using manual steel pliers, which has many drawbacks such as high labor intensity and low efficiency. The QSD-4.5 mine pneumatic cutting device (pneumatic wire quick-breaker) is a device capable of continuously and rapidly cutting wires. It operates based on pneumatic principles and is powered by the underground compressed air pipeline. The cutting range includes wires, steel wires, and anchor netting. The maximum cutting diameter is 4.5mm.

2,Features
1) Convenient power source: Air pressure power sources can be found everywhere underground.
2) No explosion problem: No electricity required, no sparks generated
3) The maximum cutting diameter exceeds 4.5mm. The conventional pneumatic cutter can only cut to a maximum of 2mm.
4) Light in weight, the main unit weighs only 1200g.
5) High efficiency, capable of continuous cutting
