摘要： PURPOSE:To detect a position of a moving body in an extensive range, by installing a pair of magnetic field detectors for the magnetic fields generated by a lead wire arranged along a travelling guide line on a moving body in inclined positions in the opposite positions. CONSTITUTION:A pair of magnetic field detectors 21, 21 are arranged on an unmanned transporter in inclined positions through an angle of theta in the opposite directions, and cables 11, 12 are installed on the ground at distances W on both sides of a travelling guide line T and the magnetic fields generated by them are detected for obtaining an amount x of the position deviation from the center of the transporter relative to the line T from the amplitude of the signal. In this case, as the center axis of the detector is inclined to the horizontal line, the range available for detection can be extended.

摘要： PURPOSE:To enable position and posture detection with high-accuracy of an excavating machine for curved excavation and automatic direction control, by installing 3 pairs and over of magnetic field detectors symmetrically on both side-surfaces of an excavating machine and a lead wire along the excavation guide line on the ground respectively. CONSTITUTION:3 pairs of magnetic field detectors 11 are installed at equal distances symmetrically on both side-surfaces of an excavating machine 1 and a lead wire 12 is installed along an excavation guide line T on the ground. Magnetic field generated by a current transmitted the wire 12 is detected by a detected and its signal is introduced into a signal processing unit for obtaining 3 position deviation values 8 relative to the guide line T. By this arrangement, horizontal position and posture of the machine can be detected continuously for curved excation and automatic direction control and avoid effect of disturbing substance if any in the ground.

摘要： PURPOSE:To correct a detection caused can sea by rolling and conduct accurate position detection, by installing a pair of magnetic field detector and a rolling angle detector on an excavating machine and arranging a lead wire along the excavation indicating line on the ground surface. CONSTITUTION:Magnetic field detectors 21, 22 are installed in the horizontally symmetrical positions on the peripheral wall of an excavating machine and a rolling angle detector 23 in the proper position respectively and magnetic fields generated by read wires 11, 12 installed along the excavation indicating line on the ground surface are detected. When an angle theta is zero, a ratio of sum and difference of the signals of the detectors 21, 22 is proportional to a deviation X of the center point of the excavator regardless of the depth y of the excavation. For existing theta, above calculated value x should be corrected according to its angle. Thus, accurate position detection can be attained by correction of any detected error caused by rolling.

摘要： PROBLEM TO BE SOLVED: To restrain a cabin box from being deformed upon turn-over of a vehicle. SOLUTION: A shock absorber 25 composed of a support shaft 26, an abutting member 27 slidably attached to the support shaft 26, and a compression spring 28 interposed between the abutting member 27 and the left side surface part 21 is provided to the left side surface part 21 of a cabin box 17. With this arrangement, the abutting member 27 impinges upon the ground surface G before the cabin box 17 reaches the ground surface G upon turn-over of a vehicle body 1, and is slid and displaced toward the cabin box 17 along the support shaft 26 so that bumping load exerted to the cabin box 17 can be absorbed through the resilient deformation of the compression spring 28. As a result, it is possible to restrain the cabin box 17 from being deformed, thereby it is possible to surely protect a driver in the cabin.
