Construction machine with function of measuring finishing accuracy of floor face smoothed thereby

摘要: A construction machine (10) with a laser measuring instrument which includes body, working apparatus, and manually operable member for driving cylinder apparatus of the to operate plurality arm members an end is constructed such that it comprises array type receiver (114) mounted on positioned free side receiving beam parallel aimed floor face irradiated from (120) disposed at position spaced away (10): posture detection structure (3-1 3-3, 4) detecting machine, control (2) controlling based result by so may receive predetermined angle. Consequently, can be driven automatically accurately received right
