SAFETY CONFIRMATION DEVICE FOR CONSTRUCTION MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a safety confirmation device for construction machine capable of judging whether or not a safety device for stopping a traveling of the construction machine is operated when an abnormal tension is generated in a crawler. SOLUTION: A detection means 5 of detecting an operation of a safety device 2 provided with a traveling stopping valve 3 for stopping a pilot pressure between a pilot valve 1 and a control valve 9 and stopping a traveling body 20 when an abnormal tension is generated in a crawler and for detecting a driving of the traveling body 20 is constituted by a pressure sensor 6 and a controller 7. In the case where the pressure sensor 6 detects a pilot pressure between the traveling stopping valve 3 and the control valve 9, a traveling signal is outputted from the controller 7 and an alarm sound is outputted by a traveling alarm 8. In the case where the pilot pressure is not detected, a traveling stopping signal is outputted from the controller 7 to stop an output of the alarm sound by the traveling alarm 8.
