Abstract

The device uses a laser beam for aligning and levelling the runway rails. The laser is placed in an emitter box (1) from where the laser beam is aimed at a target in a target housing (4). The first box is at one end of a ruler (2), while the target housing (4) is at the end of another ruler (5) which has a spirit level (7) in its middle. The target housing has a mirror angled at 45 deg within it so that the laser beam and target image can be angled upwards for viewing by an operator. A semi-reflective mirror in front of the target can be used or a semi-opaque material used for the target with the target in front of the mirror.
