摘要： PROBLEM TO BE SOLVED: To prevent the occurrence of a situation where a worker getting in a work bench makes contact with a trolley wire to get an electric shock when a high lift work is effected on a track. SOLUTION: The safety device comprises an iron wheel position detector 56 to detect whether a iron wheel 16 is positioned in an overhanging position; and a pantograph attitude detector 125 to detect whether a pantograph 120 is in an overhanging attitude. A regulation part 81 of a controller 80 outputs a regulation signal to prohibit the movement of the working bench 40 when it is detected by the pantograph attitude detector 125 that the pantograph 120 is not in an overhanging attitude. On received of the regulation signal the operation control part 81 ignores operation signals inputted from operation levers 61-64.

摘要： PROBLEM TO BE SOLVED: To prevent the possibility of fall-down of a vehicle even when malfunction or wrong operation of a reguration releasing switch occurs. SOLUTION: When an operating device 41 is operated in a preset setting time after a regulation releasing switch 43 is operated in a state where an operation regulating circuit 65 regulates the operations of actuators 8, 11, 13, 23, an operation control circuit 63 allows a regulation release control circuit 67 to release the regulation of the operation regulating circuit 65, and allows the actuators 8, 11, 13, 23 to operate based on the operation of the operating device 41. When the operating device 41 is operated after the setting time is over, the operating device stops the regulation release of the regulation release control circuit 67 to allow the operation regulating circuit 65 to perform the operation regulation.

摘要： PROBLEM TO BE SOLVED: To provide a safety device of a working means which performs a warning operation such as stopping the operation of an actuator when the operation of the working means is forcibly stopped during an operation. SOLUTION: The telescopic movement of a boom 13 is detected by an expansion/contraction detecting sensor 23, and according to the operation of a control device 21 a hydraulic pressure detector 22 detects whether or not hydraulic pressure is supplied to an expansion cylinder 17. If the expansion/ contraction detecting sensor 23 does not detect the telescopic movement of the boom 13 while the control device 21 is operated and the hydraulic pressure detector 22 detects that hydraulic pressure is supplied to the expansion cylinder 17, then a controller 25 outputs an operation stopping signal. An operation stopping device 28 stops the operation of an expansion valve 17a in response to the signal from the controller 25 to shut off the supply of the hydraulic pressure to the expansion cylinder 17.

摘要： PROBLEM TO BE SOLVED: To provide a direction change controlling device for boom tip, with which the advancing direction can be varied gradually in case the direction of the boom tip is changed during the straight movement in the plane moving mode. SOLUTION: In case the input vector P1 is different from the fore-step output vector Q0 (S11), an increment vector Δ is set (S14) while the fore-step output vector Q0 is used as reference vector and the input vector P1 is used as target vector T (S13), and intermediate vectors Q1, Q2... approaching the target vector T multi-steppedly are outputted one by one while a step-by-step increase is made from the reference vector Q0 by an amount of increment vector Δ (S15 and S16), and finally the target vector T is outputted. If thereby a direction change of boom tip is made, the advancing direction is varied gradually.

摘要： PURPOSE: To certainly carry out abnormality judgement of the detector of a working device by judging it as abnormality at the time of nonconformity by finding specified variation, time to detect that a working means works or working speed during the time from an operation point of time by the working means and comparing them with specified time and specified speed when diagnosis instruction is output. CONSTITUTION: A boom is extended and actuated by charging an operation lever for extension and contraction work to the side of extension in the case of, for example, diagnosing an extension amount sensor 13. Simultaneously, a judging apparatus 23 receives an operation signal from an operation detector 21 provided on the side of extension and selects what to correspond with extension work from a memorized specified signal. The judging apparatus 23 memorizes extension length by the extension amount sensor 13 at that time and resets a timer 24 by switching on a diagnosis switch 22. Additionally, the boom is actuated at high speed by switching an acceleration switch 8b. Furthermore, time to be specified extension length is counted by the timer 24, and it is compared with specified time. At the time of abnormality is displayed on an abnormality display 25.
