2. Webinar Objectives Provide a high-level overview of the 80m XHD Underscore critical installation steps Answer your questions Share next steps and resources This webinar DOES NOT replace a thorough review of the 80m XHD Manual 3. Webinar Agenda Introduction 80m XHD tower overview Testing and beta program Design Installation Lighting and compliance Critical Steps and Safety Q&A Wrap-up 4. Testing and Beta Program Laboratory tests ofOff-site laboratorybase plate and jointstests on guy wire (axial and bending)breaking strengths 5.

Maximum anchor load: 12,400lbf (5625 kgf). CRITICAL STEP:Anchors must be pull-testedto 15,000 lbf (6804 kgf). 12. InstallationJoint Assembly1. Hold top fastener up while tubes are slid together.2. Using a block of wood and sledge hammer, pound 2 to 3 times to seat joint.3. Using a torque wrench, torque 5/8 11 nuts to 203 Nm (150 ft-lbs). 13. InstallationGinpole and Jumper-struts CRITICAL STEP:2Jumper-strut cables must betensioned to 1000 lbf usingprovided tension gauge. 14.
