摘要： PURPOSE:To almost perfectly exclude erroneous operation, by outputting ultrasonic waves for searching a target from two places on a working vehicle in different time zones and separately calculating the distances between two places on the working vehicle and the target. CONSTITUTION:Two ultrasonic transmitter-receivers 2A, 2C are respectively mounted to one surface of a working vehicle 2 at an equal interval at the same height and separately driven by the second and third transmitting and receiving circuits 20, 30 together provided separately. When a worker being a target carries an ultrasonic transmitting and receiving means 4 to be positioned at a point P, a position determining means 50 sends specified position data to a region judge means 51. The region judge means 51 compares this input signal with the data x0, y0 relating to a preliminarily mounted dangerous region immediately and, when x

摘要： PURPOSE:To prevent erroneous operation, by outputting an ultrasonic wave for searching a target from a working vehicle and outputting a return ultrasonic wave having frequency different from that of the aforementioned ultrasonic wave from the target receiving said ultrasonic wave. CONSTITUTION:When the whole of an apparatus enters an operating state, the exciting signal of predetermined frequency outputted from the second drive circuit 22 is sent to a searching ultrasonic transmitting and receiving means 2 through the second switch circuit 21 and three ultrasonic transmitter-receivers 2A, 2B, 2C are simultaneously operated to simultaneously output searching ultrasonic wave. A return ultrasonic wave having frequency different from that of each of the searching ultrasonic waves is outputted from an ultrasonic transmitter-receiver 10 and detected by either one of the ultrasonic transmitter- receivers 2A, 2B, 2C of the searching receiving means 2 in a receiving state. When a target is present within a dangerous distance, a signal circuit 30 outputs a predetermined signal through an interface 40 to operate an alarm means 50 and the brake control means 60 of a roller vehicle is actuated to stop said vehicle.

摘要： PURPOSE:To attain labor-saving and simplification of operations by a method in which an optional vehicular height and desired excavation position and height are designated before traveling, and when the excavator travels, signals are sent out from an excavation data processing mechanism to control the position and arm angle. CONSTITUTION:When traveling is started, the present traveling position of a bulldozer 18 is calculated in an excavation data processing mechanism 32. When the present traveling position reaches a given nearby area of a target site, HSET is sent out from the mechanism 32, and arm angle alphan is controlled to be HP=HSET in an arm angle control mechanism 40. On the target site, the height is set automatically to a desired excavation height HSET. The desired excavation position and height can be preset, and when the excavation position is reached, arm angle can be automatically controlled.

摘要： PURPOSE:To simplify the operation of an excavator by a method in which the vehicular height is designated from an initial height setter, an excavation height is designated from an excavation height setter on site, and the angle of arm is controlled and displayed on an excavation height displayer. CONSTITUTION:An excavator is run by designating an optional vehicular height HS from an initial height setter 12 before traveling, and on a target site, a desired excavation height HSET is designated from an excavation height setter 39. By an arm angle control mechanism 40, arm angle alphan is controlled to be HP=HSET, where HP is the height of excavation. A desired excavation height HSET is automatically set on the target site and the excavation height HP is displayed on an excavation height displayer 16. The excavation height can thus be set automatically to a set value quickly and exactly.

摘要： PURPOSE:To simplify operations as well as raise the efficiency of operations by a method in which when the present traveling position reaches a target site, arm angle is controlled, mode setter is set to reset mode, and traveling during the learning travel period is reproduced. CONSTITUTION:When traveling is started, the present traveling position of a bulldozer 18 is calculated in an excavation data processing mechanism 32. When the present traveling position reaches a given nearby area of a target site, arm angle alphan is controlled in an arm angle control mechanism 40. When traveling is started by setting a mode setter 60 to a reset mode, a traveling controller in the arithmetic unit 54 is operated and the traveling during the learning travel period is reproduced. In case where excavation is made by repeating the same processes whatever times, learning traveling is made and automatic traveling can be made in such a way as to reproduce the traveling during the learning travel period.

摘要： PURPOSE:To confirm an object of measurement whenever necessary by providing a through-hole for the confirmation of the object of measurement between ultrasonic wave transmitter-receivers. CONSTITUTION:A partition wall 11A is provided at the center part of a main body case 11. Ultrasonic wave transmitter-receivers 12 and 13 are provided on both sides of the partition wall 11a at symmetrical positions in a slight slanting state so that their transmission and reception surfaces face each other. The through-hole 30 is formed in the center of the partition wall 11A. This through hole 30 is large enough to view or light the intersection of the center lines of the ultrasonic wave transmitter-receivers 12 and 13. Consequently, the measurement surface at the center position where an ultrasonic wave is reflected actually is confirmed through the through-hole 30 during the operation of a device.
