This machine with electro-hydraulic drive NSU 1E may be used as a drilling machine, a side loader, a ripping machine, for a rock breaking of floor and a mining cross section cleaning in mining environment with methane explosion danger up to the level IM2.

Used for the boreholes drilling that are destined for firing, anchorage and also prognosis boreholes, for mechanization the tunnel floor, that means using the machine for the purpose to disintegrate the rock, scrape and pick up rock from the tunnel floor and offloading it onto conveying machinery. Breaking the rock to pieces is made by the force of the power-full breaking hammer. The loading is realized by the rotating ripping shovel 0,35 m3 or solid side discharge shovel with the capacity 0,6 m3 or 0,8 m3. These operations are made easier by drawing movement of the shovel. Unloading the shovel is realized through dislodging the rock by the shifting plate. The quick-coupling equipment on the boom allows very easy exchange of single accessories.

The optional accessories of the universal machine are – the drilling unit, the side discharge shovel, the ripping shovel, the breaking hammer, the rotating cutter and the working platform.

Type P3 – the machine is used as a mining shovel-type side loader to drawing the disintegrated lump rock when drifting mine workings. Then is the disintegrated lump rock transported to the emptying place and unloaded onto the outgoing conveyor (e.g. scraping conveyor). Loading the disintegrated lump rock is done by using machine travel and drawing movement of the shovel. The shovel unloading is performed by the side tilt.
