摘要： PROBLEM TO BE SOLVED: To easily and quickly adjust the attitude of a working table and improve working efficiency. SOLUTION: In a controller, a reference point O is set as a coordinate value for a XY coordinate system in a level surface fixed to a working table 20. An arithmetic unit controls the operation of a boom 16 and the working table 20 in association so that a vertical post 19 can be moved on a circular arc (circumference) S having a vertical axis passing through the reference point O as a center and a distance between the vertical axis and the vertical post 19 as a radius L while fixing a spatial position of the reference point O, without changing XY coordinate values (x1, y1) for the reference point O, when an operation signal is input from an oscillatable operation lever.

摘要： PROBLEM TO BE SOLVED: To perform moving operation of a working bench by lever operation matching with the sense of a human being by operating a twist around a shaft. SOLUTION: In an ordinary mode, tilting operation in the longitudinal direction of a boom operating lever 31 to the derricking operation command of a boom 16, tilting operation in the left and right direction to the expansible operation command of the boom 16, twist operation around a shaft to the turning operation command of the boom 16, respectively correspond. Hereat, when the boom operating lever 31 is tiltingly operated in the oblique direction, the derricking operation and the expansible operation of the boom 16 are simultaneously executed. When the tilting operation and the twist operation are simultaneously executed, simultaneously with the derricking and expansible operations of the boom 16, the turning operation of the boom 16 is executed. Further, a computing device operates a shaking motor driving device, based on an output shaking operation signal. Hereby, by tiltingly operating the working bench operating lever 32, a working bench 20 can be shaked around a vertical post 19.

摘要： PROBLEM TO BE SOLVED: To provide a working table unit which can solve problems that arise because the working table unit is freely removable. SOLUTION: When a working table unit 30 is completely mounted at a boom end, both of limit switches 41, 42 are turned on. The limit switches 41, 42 are connected in series with a power supply path leading from batteries to devices. Therefore, no power is supplied to the devices unless both of the limit switches 41, 42 are turned on with the working table unit 30 completely mounted, and thus power is automatically turned off. Therefore, the output of a control signal from an upper part control device 40 when the operation of an upper part is performed with the working table unit 30 not completely mounted is limited. Also, the exhaustion of the batteries is prevented if the working table unit 30 is removed with a power switch kept on.

摘要： PROBLEM TO BE SOLVED: To prevent working in a state where a boom does not expand more than specified length by providing a contraction work limiting means to limit contraction work of the boom to less than specified length by a signal from a boom length detector. SOLUTION: When expansion length of a boom reaches specified length set on a setter 28 when an operator boarding a working bench works to contract the boom by operating an operation device 30 at the time of working by using high lift working vehicle, a comparing computing element 26 outputs a signal to a contraction work controlling device 27, a control valve 33 is changed over and communicates a pipeline 38 and unloads pressure oil discharged from a hydraulic source 35 to a tank 36 through the pipeline 38 without supplying it to an expansion cylinder 14. Consequently, contraction work of the boom to less than specified length is limited, it is possible to sufficiently secure an electric insulating property between the working bench and a car body.

摘要： PROBLEM TO BE SOLVED: To provide an energy saving device of a vehicle for high lift work, capable of stopping an electric driving means of a boom when the boom operation is performed beyond the boom operating end. SOLUTION: A controller 23 starts an electric motor 21 and sets a control valve 25 after receiving the operation command from an operating device 26. Operating oil is supplied from a hydraulic pump 22 by starting of the electric motor 21, and the boom operation is performed. The detected value of a length detecting unit 31 exceeds the prescribed value, the controller 23 switches the control valve 25 and also stops the electric motor 21. Therefore, the boom is stopped. Even if the operation is performed in the direction beyond the boom operating end by making a mistake in operation, the setting operation of the control valve 25 and the starting operation of the electric motor 21 are not performed since the operating amount is already exceeds the prescribed value.

摘要： PURPOSE: To surely perform regulation of boom action such as making supporting of a car body unstable, by a simple constitution. CONSTITUTION: An actual work position is obtained from an actual derricking angle detected by a derricking motion sensor 22 and from an actual extending amount detected by an extension sensor 23 by using an actual work position arithmetic device 26, to obtain a limit work range based on an actual loading load of a work bench detected by a load sensor 20, also to compare this range with the actual work position, and when it leads to a boundary of the limit work range, operating a boom in a direction, that the actual work position exceeds the limit work range to move, is regulated by a boom controller 28. Further, whether the actual loading of the work bench is larger or not than a permissible maximum loading load is detected by a load comparator 24, to perform alarm action by an alarm controller 30 when the actual loading load comes to be the permissible maximum loading load or more.

摘要： PURPOSE: To make a proper error judgment according physical amounts (load, etc.) to be detected by making an error judgment when a detected value is out of a specified range, and setting a lower limit value in a specified range larger as the actual physical amounts to be detected become larger. CONSTITUTION: The lower limit voltage value in an output voltage error range (specified range) to be allowed for a load sensor 21 is set larger as a load becomes larger, and the upper limit voltage value is set at a constant regardless of the magnitude of the load. Also, based on a detection signal from an elevating angle sensor 22 and an extension amount sensor 31, an error judging device 32 selects the lower limit value corresponding to the current elevating angle and extension amount of the boom of a crane vehicle from an error judging map. Then, when an output voltage value from the load sensor 21 lowers below the lower limit voltage value, it judges that an error occurred in the load sensor 21. The error judging device 32 which judged that an error occurred in the load sensor 21 transmits a display signal to an error displaying device 35.
