3.2 Manpower Requirements An installation group comprises one 3-man team. An Andrew representative exercises the quality control function. If cable sections are lifted onto supports manually, a minimum of four people are needed for lifting. 3.3 General Procedure Cable sections are delivered along a route to keep pace with the progress of installation. Installation begins at the transmitter and proceeds continually toward the antenna. On multiple-cable supports, several cable runs may be installed at the same time. 3.4 Distribute Cable at Site (One 3-man Team) Attach 35-foot (10.7 m) lifting straps near each end and at the center of one cable section in the container. Use a 40-foot (12.2 m) spreader bar to support the straps at the same spacing. Use a 2.5-ton (2268 kg) crane to lift the section from the container to a flatbed truck for distribution. CAUTION: All sections tagged because of zero pressure should be segregated. DO NOT USE THESE SECTIONS UNTIL THEY ARE INSPECTED, PURGED, AND HIGH VOLTAGE TESTED PER THE PROCEDURE IN PARAGRAPH 5.1.2. Starting with the top layer, remove each layer of sections in the container before beginning removal of sections from the next layer. Use care to avoid damage to the cable section. CAUTION: DO NOT WALK ON THE CABLE SECTIONS OR USE THE CABLE SECTIONS TO SUPPORT ANY OTHER LOAD. To attach the lifting straps to interior cable sections within the container, walk on a temporary platform that uses the styrofoam separators as a support base. Relocate the platform as required during the uploading. When uploading each 38-foot (11.6 m) cable section from the truck, support it at the center and both ends. Set it on the styrofoam cribbing from the shipping container close to the point where it will be needed. DO NOT REMOVE THE PRESSURE PLATES FROM THE CABLE SO THAT IT REMAINS UNDER AIR PRESSURE UNTIL IT IS INSTALLED. 3.5 Transmission Line Sectional Assembly An Andrew quality control representative will be on-site during the assembly and installation of the SCL950 cable. The representative will install a seal on each outer-conductor flange joint after verifying that assembly procedures and requirements have been met. 3.5.1 Attachment of Transmitter End Connector and Installation of First Section One end of each SCL950 cable section is designated as the transmitter (TX) end and the other is designated as the antenna (ANT) end. These ends are identified on labels attached to the cable section. |
