摘要：PURPOSE: To improve a workability and operability by constitutionally setting a moving regulation range to the amount of the load on a working stand. CONSTITUTION: A lever operation amount signal based on the operation of respective operation levers 26-29 and the detection signal from respective detectors 19, 20, 24 are inputted in CPU. A boom length L, undulation angleθand the amount X of the load on a working stand 22 are detected based on the signal input from an undulation angle detector 19, boom length detector 20 and oil pressure detector 24. Further, the moving regulation length Lr of the boom is calculated and a moving regulation range is set from the judgement of the amount X of the load on the working stand 22. The boom moving regulation length Lr found out by calculation is compared with the boom length L. At the time of L<=Lr, the output value of all solenoid valve is calculated and outputted and thereby, the prescribed movement of the working stand 22 is carried out. At the time of L>Lr, the excessive elongation amount of the boom is shrunk and the working stand 22 is moved to the outside of the moving regulation range.
