Abstract
In a laser beam detecting device for a construction machine, a beam sensor is installed above a leveling implement of the construction machine, a laser beam is detected by the beam sensor, and information based on the beam detection is displayed on a display. A plurality of reference positions are established in a range in which the beam sensor detects the laser beam. One of the reference positions is made a standard position, while the other reference positions are made offset positions.
