Claims

[Scope of Claim for Utility Model Registration] A hoisting block 2 is suspended from the tip of a telescopic boom 1 that can be freely undulated and rotated, and the hoisting movement, telescopic movement, and turning movement of the telescoping boom 1 and the hoisting and hoisting movement of the hoisting block 2 are controlled. Valve 7, telescopic control valve 8
, an operating device for a mobile crane, in particular, a mobile crane operating device configured to perform hoisting control by a hoisting cylinder 3, a telescopic cylinder 4, a winch motor 5, and a swing motor 6, which are driven and controlled by a winch control valve 9 and a swing control valve 10. A luffing drive direction designating switch 13 outputs a signal designating the switching direction of the valve 7, a telescopic drive direction designation switch 14 outputs a signal designating the switching direction of the telescopic control valve 8, and a telescopic drive direction designation switch 14 designates the switching direction of the winch control valve 9. A winch drive direction designation switch 15 that outputs a signal, a swing drive direction designation switch 16 that outputs a signal that designates the switching direction of the swing control valve 10, and a common switch that outputs a signal related to the operation amount of each control valve 7 to 10. a manual input section 11 having a switching amount signal generating means 17; and an arithmetic processing device 12 for receiving and processing the output signal of the manual input section 11 and outputting an operation signal to each of the control valves. The arithmetic processing unit 12 receives the output signals from the direction designation switches 13 to 16 of the manual input section 11 and the switching amount signal generation means 17, and controls the control valve corresponding to the direction designation switch to be operated. A boom hoisting angle detector for detecting the hoisting angle of the telescoping boom 1, which is configured to output an operation signal to a corresponding control valve to switch an amount related to the output signal of the switching amount signal generating means 17 in a specified direction. 45 and a boom length detector 46 for detecting the length of the telescopic boom 1.
4 is input into the arithmetic processing device 12, and the arithmetic processing device 12 receives a hoisting signal (or lodging signal) of the telescopic boom 1 from the hoisting drive direction designation switch 13 of the manual input section 11, and When an extension signal (or reduction signal) for the telescopic boom 1 is received from the telescopic drive direction designation switch 14, the raising direction (or lowering direction) of the luffing control valve 7 is set so that the tip position of the telescopic boom 1 moves almost vertically. an operation signal that instructs the amount of switching to;
An operation signal instructing the switching amount in the extension direction (or contraction direction) of the telescopic control valve 8 is inputted from the operating attitude information from the boom operating attitude detection means 44 and the signal from the switching amount signal generating means 17 of the manual input section 11. An operating device for a mobile crane, characterized in that it is configured to perform calculations using.
