7 Section 1. General Information The Heavy Duty Adjustable Tripod is a robust scientific instrument platform designed to support LI-COR eddy covariance systems and sensor arrays in long-term field deployments. It can accommodate a simple eddy covariance system, consisting of an LI-7500RS and a sonic anemometer, or a fully outfitted system with an LI-7200RS, Flow Module, LI-7700 CH 4 Analyzer, ancillary sensors, a Biomet system, and more. It is designed withstand extreme outdoor conditions, including high wind conditions. Safety Information The Heavy Duty Adjustable Tripod has been designed to be safe when operated in the manner described in this manual. The safety of this product cannot be guaranteed if the product is used in any other way than described in this manual. These instructions include the following markings: Warning: A warning means that injury or death is possible if the instructions are not obeyed. Caution: A caution means that damage to equipment or compromised data/- experimental results are possible if the instructions are not obeyed. Note: Notes are added to give more information about a procedure or topic. The equipment includes the following markings: This symbol indicates that the user must read the instruction manual prior to assembling or using the tripod. 1-1

8 Section 1. General Information This symbol indicates that it is mandatory to check for overhead power lines prior to assembling the tripod. This symbol indicates that the tripod is not suitable for stepping or climbing. This label indicates that users should never lean a ladder against the tripod. Precautions Warning: Read all the instructions in this manual prior to assembling, moving, or disassembling the tripod. Warning: Never cover or conceal the safety labels that are attached to the tripod. Doing so could lead one to fail to observe the safety warnings and sustain personal injury or damage to equipment through the use of the tripod. Warning: Assembly of the Adjustable Heavy Duty Tripod should be carried out with a minimum of two people. Attempts to assemble the tripod with an insufficient number of people could lead to personal injury. Caution: Each stake must withstand kg (608 lbs) of lateral load and kg (886 lbs) of downward load in order to meet the 161 kph (100 mph) wind load specification. These conditions are met if the tripod is installed as described in this manual. If your site conditions deviate from those described here (see "Soil Conditions" on page 1-5) select an alternate site. Warning: Conduct a pre-installation site visit to determine proper soil composition for a successful tripod installation. Acceptable soil conditions (see Soil Conditions on page 1-5) should be studied in advance of the pre-installation trip. 1-2

9 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 installation 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. If you have these conditions, consult with a local geotechnical engineer to determine whether soil at your site is suitable for the tripod. Warning: The tripod may not be adequate for every situation depending on soil structure, maximum wind speeds experienced at the site, mast height, or wind load from the instrumentation. If uncertain, seek the advice of structural and geotechnical engineers. Warning: It may not always be possible to plumb the tripod mast with the leg adjustments. The tripod should not deviate more than 2.3 from true vertical (approximately 15.2 cm (6 in) of deviation at the top of the upper mast). Make sure your experiment objectives will not be adversely affected by the deviation from plumb. If the mast deviates from vertical, it should lean toward the uphill side. Make sure the feet - especially the downhill feet - are firmly anchored on solid ground (see "Install the Foot Stakes" on page 2-14). Warning: Never lean a ladder against the tripod. Doing so may cause structural failure and result in severe injury, death, and/or damage to equipment. Warning: Never step on the legs or leg braces; and never attempt to climb the tripod. Doing so may result in severe injury, death, and/or damage to equipment. Warning: Do not hang from the tripod or cross arm. Doing so may cause the tripod to fall or fail, and result in severe injury, death, and/or damage to equipment. Precautions 1-3

10 Section 1. General Information Site Selection Warning: Never weld the tripod or attach a bracket that serves to support a climbing apparatus. Doing so will compromise the strength of the tripod and may result in injury, death, and/or damage to equipment. Careful site selection will provide simpler setup and ensure that your sensors collect high-quality, representative data. The site should accommodate the tripod and guy wires without interfering with any of the tripod components. The feet require an unobstructed area with a 2.54 m (8 ft 4 in) diameter. The guy wires require an area with an 8 m (26 ft 3 in) diameter. As a general rule, disturb the site as little as possible. Prior to assembling the tripod, remove any woody brush or tall plants that are in the way of the tripod feet and guy wires. Warning: It is dangerous to install the tripod close to overhead power lines, buried power lines, underground gas lines, or unexploded ordnances. Keep a minimum distance of at least 2 times the height of the tripod (including the lightning rod) between the tripod and nearest overhead line. Prior to installing the ground rod or anchors, be sure that there are no underground utilities, power lines, unexploded ordnances, or other installations at your site. 1-4

11 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. This soil would be defined as Class 6 in accordance with the literature of Foresight Products, the manufacturer of the Duckbill Model 68 earth anchors intended for use with the tripod. The tripod is not to be installed in clean sands or gravels. Aluminum that is in contact with soil with a ph above 8.5 or below 4.5 (e.g., nondraining clay-organic and fertilized fields) will corrode faster. If your site has soil that meets these conditions take measures to physically separate the aluminum feet from the soil (e.g., place a sheet of sturdy plastic from a heavy duty trash bag between the metal and soil) and check the condition of the feet and stakes regularly. 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 installation 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. If you have these conditions, consult with a local geotechnical engineer to determine whether soil at your site is suitable for the tripod. Soil Conditions 1-5

29 Section 2. Assembling the Tripod 8 Install the Guy Wires on the Mast Insert a cable thimble into each of the cable holes in the guy wire fitting. To view a video tutorial of steps 8 through 10 scan this with a QR code reader or select Steps 8-10 from Warning: The earth anchor cables are stiff, corrosion resistant wire rope. Wear gloves and safety goggles when handling them. Then, insert about 22.9 cm (9 inches) of the cable through the Gripple according to the arrows on the Gripple. To release the Gripple see Tighten the Guy Cables on page Route the cable around the thimble, through the guy wire fitting, and secure it through the other side of the Gripple. The cable should extend at least 7.6 cm (3 in) past the Gripple. Repeat this for each guy wire. Section 2. Assembling the Tripod 2-7

30 Section 2. Assembling the Tripod 9 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. 10 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. Set two legs in position and lift the mast until the tripod is in the vertical position. Enlist the help of an assistant if needed. 2-8

31 Section 2. Assembling the Tripod 11 Drive the Mast Anchor into the Ground The earth anchor is to secure the mast to the ground. Think ahead about the position of the tripod - or even set the tripod in position, then identify the point on the ground where the anchor should be driven. Position the anchor so the cable will lead to the mast anchor attachment point. Set the tripod aside and drive the anchor. Note: Do not attach the mast anchor to the mast yet. To view a video tutorial of steps 11 through 16 scan this with a QR code reader or select Steps from Warning: Read the notes on site selection (see Site Selection on page 1-4) before determining the final location for the tripod. Use the 91.4 cm (36 inch) driving rod, drive the anchor to a depth of 85 cm (33.5 inches). Depth of 85 cm (33.5 in) Warning: The earth anchor cables are stiff, corrosion resistant wire rope. Wear gloves and safety goggles when handling them. Pull firmly on the cable......to rotate the anchor underground. Section 2. Assembling the Tripod 2-9

32 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 tripod 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. 12 Install the Ground Rod Position the ground rod 46 to 61 cm (18 to 24 in) from the mast/earth anchor. Drive it into the ground with a hammer or post driver, leaving about 10 cm (4 in) above the ground. Note: Slide the ground rod clasp on the ground rod prior to driving the rod into the ground. The tip of the ground rod may become deformed as it is driven, making it impossible to install the ground wire clasp afterwards. 2-10

33 Section 2. Assembling the Tripod 13 Plumb the Mast Move the tripod into the desired position and use a torpedo level to check the vertical 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. Each leg has 2 adjustment holes spaced at 15.2 cm (6 in), whereas each leg extension has 6 adjustment holes spaced at 10.2 cm (4 in). Warning: It may not always be possible to plumb the tripod mast with the leg adjustments. The tripod should not deviate more than 2.3 from true vertical (approximately 15.2 cm (6 in) of deviation at the top of the upper mast). Make sure your experiment objectives will not be adversely affected by the deviation from plumb. If the mast deviates from vertical, it should lean toward the uphill side. Make sure the feet - especially the downhill feet - are firmly anchored on solid ground (see "Install the Foot Stakes" on page 2-14). Section 2. Assembling the Tripod 2-11

34 Section 2. Assembling the Tripod 14 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; 7 lb ft), the guy wire fitting to 23 N m (204 lb in; 17 lb ft), and the upper mast nut and bolt to 23 N m (204 lb in; 17 lb ft). 2-12

35 Section 2. Assembling the Tripod 15 Connect the Mast Anchor Insert a thimble into the anchor point on the mast. Warning: The earth anchor cables are stiff, corrosion resistant wire rope. Wear gloves and safety goggles when handling them. Insert cm (9 in) of earth anchor cable into a Gripple according to the arrows that are visible on the exterior of the Gripple device, loop it through a thimble, and then back into the Gripple. Tighten the cable securely around the thimble. To tighten the cable, hold the Gripple in one hand and pull the end of the cable through the Gripple. Coil any extra cable and secure it with zip ties. To release the Gripple see Tighten the Guy Cables on page Section 2. Assembling the Tripod 2-13

36 Section 2. Assembling the Tripod 16 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 opposite corners of each foot. It is normal for the top of each stake to deform when it is driven. Note: Before installing the stakes, be sure the tripod is positioned exactly as desired and that the mast is vertical (see Plumb the Mast on page 2-11). Adjustments are more difficult after the foot stakes have been installed. Caution: Each foot must withstand kg (608 lbs) of lateral load and kg (886 lbs) of downward load in order to meet the 161 kph (100 mph) wind load specification. These conditions are met if the tripod foot stakes are installed as described in this manual. If your site conditions deviate from those described here (seesoil Conditions on page 1-5) select an alternate site. Warning: The stakes should be driven into opposite corners of each foot for maximum stability. Never drive the anchors into adjacent corners. Note: If the soil ph is above 8.5 or below 4.5 (e.g., non-draining clay-organic and fertilized fields) the aluminum that is in contact with the soil will corrode faster. For more information see Soil Conditions on page

37 Section 2. Assembling the Tripod 17 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. Pull at least 7.62 cm (3 inches) of cable through the Gripple. To view a video tutorial of steps 17 through 19 scan this with a QR code reader select Steps from Warning: The earth anchor cables are stiff, corrosion resistant wire rope. Wear gloves and safety goggles when handling them. Assemble the earth anchors, thimble and Gripple as shown. Warning: Check to be sure that there are no underground utilities or unexploded buried ordnance prior to installing the earth anchors. Failure to do so could result in severe bodily injury, death and/or damage to equipment. Caution: In order to meet the 161 kph (100 mph) wind load specification, each anchor must withstand kg (397 lbs) of force. The supplied anchors do this, provided that the tripod is installed in the recommended soil conditions. If soil conditions at your site deviate from those described here (see Soil Conditions on page 1-5) select an alternate site. Guy wires should be positioned at a 45 angle between the mast and earth anchors, as shown in the following figure. Vertical distances are between the ground and the top of the guy wire fitting. Horizontal distances are from the mast to the earth anchor. Determine the location for each earth anchor with the tripod in its final position. Section 2. Assembling the Tripod 2-15

38 Section 2. Assembling the Tripod 3.9 m (12 ft 10 in) 3.7 m (12 ft 2 in) 3.4 m (11 ft 2 in) 3.1 m (10 ft 2 in) 2.8 m (9 ft 2 in) 2.5 m (8 ft 2 in) 2.3 m (7 ft 7 in) m (7 ft 7 in) 2.5 m (8 ft 2 in) 2.8 m (9 ft 2 in) 3.1 m (10 ft 2 in) 3.4 m (11 ft 2in) 3.7 m (12 ft 2 in) 3.9 m (12 ft 10 in) Use the Earth anchor driving rod and a sledge hammer to drive each anchor to a depth of 85 cm (33.5 inches). Each anchor should be driven at a 45 angle along the same axis as the corresponding guy wire. Pull firmly on the cable... Anchor Driving Rod Note the orientation of the anchor to rotate the anchor underground. Each anchor must be set after it is driven. Insert the driving rod into the cable thimble and pull firmly on the cable. You will feel the cable pull out several centimeters (about an inch) when the anchor rotates in the ground and locks in place. 2-16

39 Section 2. Assembling the Tripod 18 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. Grab the Gripple and pull to get the cable snug. Coil any extra cable and secure it with cable ties. Warning: The earth anchor cables are stiff, corrosion resistant wire rope. Wear gloves and safety goggles when handling them. Warning: Do not over tighten the guy wires. When the guy wires are properly tightened there will be slight slack in the cable. Excessively tightened guy wires apply a load to the tower, diminishing its ability to support the sensors. Note: Position the upper guy wire Gripple as high up the cable as possible. When it is necessary to remove the cable, you can cut the cable close to the Gripple, preserving a significant portion of the cable for reuse. Section 2. Assembling the Tripod 2-17

40 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. 19 If there is tension on the cable it may be helpful to relieve the tension. When the Gripple release key has been pressed with sufficient pressure, the Gripple will release the cable, allowing you to move the cable freely within the Gripple. Install the Ground Wire Install the ground wire between the ground rod and the mast. Note: The bolt in the ground rod clasp is a torque-limiting bolt that will break if it is overtightened. Tighten it snugly onto the ground rod and ground wire. 2-18

41 Section 2. Assembling the Tripod 20 Verify the Stability of the Tripod As a final step, verify the stability of the tripod to ensure it is assembled properly. Double check the vertical orientation of the tripod using a level (see Plumb the Mast on page 2-11). Check each nut and bolt to verify that each is tightened to the torque specification (see Torque the Nuts and Bolts on page 2-12). Check the tightness of the guy cables and mast anchor.

43 Section 3. Maintenance Monthly Every 6 Months Several routine maintenance procedures will ensure that the tripod is stable over time. Perform a visual inspection for damage or wear. Check the orientation of the tripod to ensure that it has not slipped out of plumb and that the mast is level (see Plumb the Mast on page 2-11). Check the tightness of each nut and bolt. Tighten each to the torque specification listed in these instructions (see Torque the Nuts and Bolts on page 2-12). Check the tightness of the guy wires. Each guy wire should be snug with slight slack. Tighten or loosen the Gripple connectors to adjust the slack (see Tighten the Guy Cables on page 2-17). Check the lightning rod, ground rod, ground wire, and ground connections. Tighten any loose mounts or connections (see Install the Lightning Rod on page 2-8, Install the Lightning Rod on page 2-8, and Install the Ground Wire on page 2-18). If soils are corrosive, check the feet and stakes for corrosion. If substantial corrosion is evident replace the feet and/or stakes. Look for corroded bolts, corroded welds, or other abnormalities. Replace damaged hardware and take appropriate corrective measures if you observe any damaged or worn parts. 3-1
