CABLE LAYING APPARATUS AND CABLE LAYING METHOD FOR MULTI-STAGE CABLE TRAY

摘要

Disclosed is a cable laying method for a multi-stage cable tray. A cable laying method for a multi-stage cable tray according to the embodiment of the present invention, includes installing a transport device having a movable pressure roller which can move vertically, to the uppermost layer of a multi-stage cable tray, installing a guide device which has a guide roller in a position which faces the pressure roller in a cable tray for laying a cable among the multi-stage cable trays, pressurizing a cable located between the pressure roller and the guide roller by moving the pressure roller downwards, completing a laying process by applying a transport force to the cable by pushing the cable due to the rotation of the pressure roller and the guide roller, separating the guide device after moving the pressure roller upwards, installing the guide device to another cable tray among the multi-stage cable trays, and performing a laying process by using the transport device and the guide device.
