Laser Alignment System UNL

The Laser Alignment Systems UNL are designed for fixing horizontal and incline reference directions in tunnels and mine workings, hazardous in mine gas and combustion dust. The Laser Systems UNL can be used for mining and tunelling.

The Laser Alignment System UNL is a lightweight, self-contained, alignment laser pointer which provides a highly visible spot of light up to a range of 800 m. The pointer is intrinsically safe and therefore presents no danger to personnel in the vicinity of operations. It is also extremely robust and is capable of withstanding rough handling and arduous environmental conditions.

OPERATION CONDITIONS:

  • environment contains explosive mixture of category I (methane in underground works) and aggressive to metals dust salt in the air;
  • ambient air temperature from 5 to +350C;
  • ambient relative humidity 98% at temperature 350C;
  • height above sea level – 1000 m, maximum;
  • depth below sea level – 1500 m, maximum.

The Laser Alignment System UNL is optically or manually adjustable.
