PURPOSE: A clamp safety device for an excavator using a magnetic strip is provided to prevent safety accidents in advance by stably fixing a clamp and an attachment with electromagnetic power. CONSTITUTION: A clam safety device for an excavator using a magnetic strip is implemented by a first and a second magnetic strip. A second magnetic(131) is formed on an inclined plate which comes most closely to a first magnetic(121) or a lower body(130) of a clamp body(10) in an inner side of the movable hook(120). An electromagnetic field is generated around the inclined plate by supplying power to a wire connected to the first and the second magnetic, and the movable hook is connected to a fixing pin. The wire is successively connected to an electrode converter(40), a voltmeter(50), a battery(60), and a power switch(70). |
