Section 1. General Information Warning: The tripod is not suitable for installation on solid rock, soils that are composed of a rocky substrate, or other hard surfaces that will not allow install- ation of any of the following: earth anchors, foot stakes, or grounding rod. In these conditions the tripod may not meet the specifications described in the instructions and additional measures may be required to stabilize the tripod.
Section 1. General Information Warning: Never weld the tripod or attach a bracket that serves to sup- port a climbing apparatus. Doing so will compromise the strength of the tripod and may result in injury, death, and/or damage to equip- ment.
Section 1. General Information Soil Conditions The Heavy Duty Adjustable Tripod can be adequately supported in “average” soil. “Average” soils are defined as stiff silts and clays containing up to 50% sand and gravel and having blow counts (N) of 8 to 16 per ASTM D 1586 and unconfined compressive strengths of 1500 to 3000 pounds per square foot.
Section 1. General Information Loading the Tripod Load the tripod according to the maximum weights and frontal areas given below. Warning: The guy kit, earth anchors, and foot stakes must be installed to meet the tripod specifications. If these components are not installed, the tripod may fall or fail, resulting in injury, death, and/or damage to equipment.

Section 2. Assembling the Tripod Legs and Base Attach One Leg to the Mast Gather the following components for one leg: lower mast, leg, leg extension, leg brace, foot, 90 mm bolts, lock washers, flat washers, and nuts. Attach the leg to the mast as shown below. Tighten the nut(s) to finger-tight for now.
Page 22
Section 2. Assembling the Tripod Attach the Leg Brace to the Mast and Leg Attach the leg brace between the leg and mast as shown below. Be sure the warn- ing label is near the mast. Warning: Pinch point. Use caution during assembly. Tighten the nut(s) to finger-tight for now.
Page 23
Section 2. Assembling the Tripod Attach the Leg Extension and Foot Attach the leg extension and foot to the leg, as shown below. Warning: Pinch point. Use caution during assembly. Tighten the nut(s) to finger-tight for now. When the tripod mast and legs are com- pletely assembled, tighten it to 23 N•m (204 lb•in;...
Section 2. Assembling the Tripod Mast and Guy Wires Install the Upper Mast The upper mast extends the reach of the tripod up to 4 meters (13.12 feet). Slide the upper mast over the lower mast. Secure it with a 90 mm bolt, nut, and two washers.
Page 25
Section 2. Assembling the Tripod Position the guy wire fitting on the mast so that is as close as possible to the anticipated cross arm location. It must still be under the cross arm. Secure it with a 100 mm bolt, nut, two flat washers, and a lock washer. Tighten the nut 23 N•m (204 lbs•in;...
Page 26
Section 2. Assembling the Tripod Install the Cross Arm The cross arm mounts to the mast with the cross arm bracket. Attach the bracket to the mast with U-bolts, flat washers (24 mm M8), lock washers (M8) and nuts (13 mm M8) from the cross-arm bracket hardware bag.
Page 27
Section 2. Assembling the Tripod Install the Guy Wires on the Mast Insert a cable thimble into each of the cable holes in the guy wire fitting. Warning: The earth anchor cables are stiff, corrosion res- istant wire rope. Wear gloves and safety goggles when hand- ling them.
Page 28
Section 2. Assembling the Tripod Install the Lightning Rod Install two lightning rod clamps as shown below. Attach the lightning rod to the mast with the two clamps. Use an 8 mm hex key to tighten the lightning rod. Raise the Tripod Prior to raising the tripod, consider access to the site, the position of the cross-arm with respect to expected orientation of sensors, and wind direction.
Section 2. Assembling the Tripod Anchor the Tripod Drive the Mast Anchor into the Ground The earth anchor is to secure the mast to the ground. Think ahead about the pos- ition of the tripod—or even set the tripod in position, then identify the point on the ground where the anchor should be driven.
Page 30
Section 2. Assembling the Tripod When setting the earth anchor, the cable will give several centimeters (~1 inch) when the anchor rotates underground. Caution: When installed in suitable soil (see Soil Conditions on page 1-5), the tri- pod can withstand a 161 kph (100 mph) wind while supporting a load. If soil conditions deviate from those described here, take measures to ensure that the mast anchor can withstand 392 kg (864 lbs) of upward force in order to ensure that the tripod will meet the wind and load specifications.
Page 31
Section 2. Assembling the Tripod Plumb the Mast Move the tripod into the desired position and use a torpedo level to check the ver- tical orientation of the mast on adjacent sides. Adjust one or more legs until the level indicates that the mast is plumb. Each leg can be extended or retracted in 5.1 cm (2 in) increments.
Page 32
Section 2. Assembling the Tripod Torque the Nuts and Bolts Tighten the nuts and bolts on the legs, leg extensions, leg braces and feet to 23 N•m (204 lb•in; 17 lb•ft). If not adequately tightened in the previous steps, tighten the cross arm nuts to 9.6 N•m (85 lb•in;...

Section 2. Assembling the Tripod Connect the Mast Anchor Insert a thimble into the anchor point on the mast. Warning: The earth anchor cables are stiff, corrosion res- istant wire rope. Wear gloves and safety goggles when hand- ling them. Insert 22.86 cm (9 in) of earth anchor cable into a Gripple®...

Section 2. Assembling the Tripod Install the Foot Stakes Foot stakes serve to secure the feet and prevent them from moving on the ground. Using a hammer, drive two stakes into oppos- ite corners of each foot. It is normal for the top of each stake to deform when it is driven.
Page 35
Section 2. Assembling the Tripod Install the Guy Anchors and Wires The three remaining earth anchors are to secure the guy wires. Prepare each anchor by inserting the cable into a Gripple® connector according to the arrows printed on the connector. Make a loop around a thimble and insert the other end of the cable into the Gripple.

Section 2. Assembling the Tripod Tighten the Guy Cables Finish installing each guy wire by routing the guy cable through one side of a Gripple® according to the arrows on the device, through the loop at the end of the guy anchor, and back through the Gripple, pulling at least 7.6 cm (3 in) through the Gripple.
Page 38
Section 2. Assembling the Tripod Note: To release the Gripple, locate the Gripple release key in the Guy Wire Kit. Identify the hole in the Gripple, which can be found near either one of the cable insertion points. Insert the Gripple release key into this hole and press firmly. If there is tension on the cable it may be helpful to relieve the tension.
