10. Installation
80m XHD Terrain/slope Requirements
• Terrain/slope ≤ ±3°
 Slopes greater than +1.5°
 Slopes less than -2°

11. Installation
Anchors and Pull Test 1
• Double Helix Power-Installed
Screw Anchors.
• Maximum anchor load: 12,400
lbf (5625 kgf).
• CRITICAL STEP:
Anchors must be pull-tested
to 15,000 lbf (6804 kgf).

12. Installation
Joint Assembly
1. 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. Installation
Ginpole and Jumper-struts
• CRITICAL STEP: 2
Jumper-strut cables must be
tensioned to 1000 lbf using
provided tension gauge.

14. Installation
Ginpole and Jumper-struts
• CRITICAL STEP: 3
Carefully follow the manual
instructions for reeving the
5-part line for the lift cable.

15. Installation
Winch
• 750 ft of 3/8 in diameter 4
cable.
• 3000 lbf (1361 kgf) winch
cable erection force.
• CRITICAL STEP:
Winch base plate must be
secured to winch anchor
using sling provided.

16. Installation Toolkit
Toolkit Includes: 5
• Chicago grip
• Come-along
• Shackles
• CRITICAL STEP:
Mechanical tensioning
is required to tension
guy wires.

21. Summary of Key 80m/60m
Differences

22. Final Thoughts
• 60m XHD performance at 80m
• More steel means more weight
• Similar installation, new tools
and anchoring required
• Thoroughly review the 80m
XHD Manual
