<p>PURPOSE:To prevent a cable from damaging at cable laying time by providing a cable extending guide unit at a cable tray. CONSTITUTION:A cable extending guide unit 8 is provided within a cable tray 2. The shaft 10 of the unit 8 is mounted at the one end thereof at the side plate of the tray 2 through a universal joint 13 with mounting bracket 14 and at the other at the side plate of the tray 2 with anchoring bracket 15. The shaft 10 incorporates horizontal rollers 11 and vertical roller 12 to reduce the tension under the guidance of the cable. The shaft 10 further can rotate via the joint 13 and drop the cable into the tray 2 by placing the rollers 12 horizontally and the shaft 10 in parallel with the side plate of the tray 2 after laying the cable. Thus, it can easily lay the cable without damaging the cable.</p> |
