EMERGENCY SHUTDOWN DEVICE AND EMERGENCY SHUTDOWN METHOD OF CONSTRUCTION MACHINE

摘要

PROBLEM TO BE SOLVED: To secure safety of a worker who works around a construction machine.SOLUTION: When a worker 280 who wears an IC tag 260 emitting an electric wave in response to a magnetic field comes into the magnetic field (predetermined range A) generated by a magnetic field generation device 220 mounted on a tire roller 100 with a negative brake, an emergency shutdown device shuts down an engine of the tire roller 100 by detecting the electric wave emitted from the IC tag 260. When the engine of the tire roller 100 is shut down, the negative brake is operated to immediately stop the tire roller 100.SELECTED DRAWING: Figure 9
