METHOD OF INSPECTING LIFTING WIRE OF LIFTING DEVICE AND LIFTING DEVICE USING SAME

摘要

The present invention relates to a method of inspecting a lifting wire of a lifting device and a lifting device using the same to replace or inspect a lifting wire in accordance with the number of ascents of an ascending body. According to embodiments of the present invention, the method of inspecting a lifting wire of a lifting device including a lifting main body including a winding drum to wind a lifting wire thereon and a drive motor to provide driving power to rotate the winding drum, an ascending body to couple a high-place installation device hung on the lifting wire to ascend, and a lifting control controller to control the drive motor to control an ascent of the ascending body comprises: a step of lifting or lowering the ascending body hung on the lifting wire in a form of rotating the winding drum by operating the drive motor; a step of measuring the number of ascents of the ascending body based on ascending or descending information of the ascending body in accordance with an operation of the drive motor by the lifting control controller; and a step of un-operating the drive motor or transmitting an inspection signal for inspection of the lifting wire if the number of ascents measured by the lifting control controller is included in a preset range. Therefore, accidents are prevented by avoiding breakage of the lifting wire.;COPYRIGHT KIPO 2020
