置。 Measures the off time (stop time) of the lock device release signal in a hydraulic cylinder lock control device in a boom elevation system that uses a hydraulic or pneumatic cylinder to directly or indirectly give the boom elevation angle via a link mechanism. A timer, a timer switch activated by the timer, and two elevation delay timers are provided, and the elevation delay timer is selected so that the lock device release signal is set longer when the off time is long and shortened when the off time is short. A boom depression/elevation angle cylinder lock control device that controls an activation delay time of a hydraulic lock device.
