摘要： PROBLEM TO BE SOLVED: To shorten a standby time for DPF regeneration and inhibit an actuator from performing its action not intended by an operator during the DPF regeneration.SOLUTION: Load applying means 50 is restricted from starting a change in the load applying amount during a time when operation state detecting means 33 detects the operation of an operation lever 31 (Symbol T3a, T3b). CV command value change restricting means 34 restricts a change in a CV command value with the operation lever 31 during a time when the load applying amount of the load applying means 50 is changed (symbol T1a, T1b). The CV command value change restricting means 34 cancels the restriction of the change in the CV command value with the operation lever 31 during a time when the load applying amount of the load applying means 50 is kept constant (Symbol T2).

摘要： PROBLEM TO BE SOLVED: To inhibit an actuator from moving when loads are applied. SOLUTION: When the loads are applied to an engine 1 and a pump 3 for regenerating an exhaust emission control device 2 (in load applied state), a selector valve 21 (selecting means) is at a second switching position 21b (in second state). At this time, the pump 3 and an actuator control valve 7 are intercepted from each other, and also hydraulic oil discharged from the pump 3 can return to a hydraulic oil tank 5 through a pressure control valve 9. Therefore, when the loads are applied, the hydraulic oil discharged from the pump 3 is not supplied to the actuator control valve 7. Furthermore, the hydraulic oil is not supplied to the actuator 8(8A) whose operation is controlled by the actuator control valve 7(7A). Thus, when the loads are applied, the actuator 8 can be inhibited from moving. COPYRIGHT: (C)2011,JPO&INPIT
摘要翻译：要解决的问题：当施加负载时，阻止致动器移动。解决方案：当将负载施加到发动机1和用于再生废气排放控制装置2的泵3（负载施加状态）时，选择阀21（选择装置）处于第二切换位置21b（在第二状态）。此时，泵3和致动器控制阀7彼此截断，并且从泵3排出的液压油可以通过压力控制阀9返回到液压油箱5.因此，当施加负载时从泵3排出的液压油不供给至致动器控制阀7.此外，液压油不供给到由致动器控制阀7（7A）进行操作的致动器8（8A）。因此，当施加负载时，可以禁止致动器8移动。版权所有（C）2011，JPO＆INPIT
