Abstract
PURPOSE: To prevent vibration nuisance by enabling instantaneous start up or stoppage of a hydraulic actuator for generating vibration when the machine is started or stopped so that the vibration of the machine does not coincide with the natural frequencies of a crane boom, buildings in its vicinity and the like.
CONSTITUTION: A main selector valve 17 is interposed between a hydraulic source 16 and a hydraulic actuator 13 while a vibration valve 18 is interposed between the valve 17 and the hydraulic actuator 13. Both the valves 17 and 18 are controlled with an operator 19. When a switch not illustrated is closed, initially the operator 19 outputs an action signal of a fixed frequency to the vibration valve 18 and then an action signal of the main selector valve 17 delayed by a fixed time t1. When the switch is cut off, the action signal of the main selector valve 17 is terminated and then the action signal of the vibration valve 18 is terminated by a fixed time t2. This enables the frequency of the actuator 13 to coincide with the frequency of the vibration valve 18 from the beginning while the instantaneous stoppage is possible.
