60m vs. 80m Comparison: Installation

• Resources and Time• Terrain/slope Requirements• Anchors and Pull Test• Joint Assembly• Ginpole and Jumper-struts• Winch

Installation

Topics Covered

Resources and Time• Site layout / anchor setting: 1 day• Tube bolting: 3.5 hours• Laying out guy wires: 3.5 hours• Ginpole assembly: 1.5 hours• Lighting installation: 2.5 hours• Raising & plumbing tower: 3.5 hours

TOTAL: 3-4 days

Installation

80m XHD Terrain/slope Requirements• Terrain/slope ≤ ±3°

Slopes greater than +1.5° Slopes less than -2°

Installation

• 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).

Installation

Anchors and Pull Test 1

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).

Installation

Joint Assembly

• CRITICAL STEP:Jumper-strut cables must be tensioned to 1000 lbf using provided tension gauge.

Installation

Ginpole and Jumper-struts2

Installation

Ginpole and Jumper-struts• CRITICAL STEP:

Carefully follow the manual instructions for reeving the 5-part line for the lift cable.

3

Installation

Winch• 750 ft of 3/8 in diameter

cable.

• 3000 lbf (1361 kgf) winch cable erection force.

• CRITICAL STEP:Winch base plate must be secured to winch anchor using sling provided.

4

Installation Toolkit

• Chicago grip

• Come-along

• Shackles

• CRITICAL STEP:Mechanical tensioning is required to tension guy wires.

Toolkit Includes: 5

Summary of Key 80m/60mDifferences

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
