Document Type and Number:
WIPO Patent Application WO/1998/010147
Kind Code:
A1
Abstract:
A construction machine with a laser measuring instrument comprising a construction machine main body, a working device, and an operating member for operating a plurality of arm members and tip working members by driving a cylinder device of the working device. The construction machine further comprises an array type laser light receiving device (114) which is fitted to the free end-side arm member and receives a laser light beam emitted in parallel with a target floor surface from a laser device (120) provided away from the machine (10), attitude detecting means (3-1 to 3-3 and 4) which detects the attitude of the machine (10), and a control means (2) which controls the working device so that the light receiving device (114) can receive the laser light from the laser device (120) at a prescribed angle based on the results of detection of the detecting means (3-1 to 3-3 and 4). Therefore, the working members can be driven automatically and accurately so that the receiving device (114) can receive the laser light perpendicularly.
