Installing a Davit on a Wood Pole
Installing a Davit on a Wood Pole
The CCU4 collector is installed on the davit of a pole, which is the part of the pole that extends
out, away from the pole and is parallel to the ground. A light pole has an existing davit that holds
the light fixture, and the collector is installed about 6 in. behind the light fixture on the davit.
Wood poles do not usually have davits, but you can install one on the pole with a davit kit. If the
wood pole already has a davit attached, you do not need to add another unless installing the
collector on the davit exceeds the wind load rating of the davit, creates RF interference with other
equipment on or near the pole, or places the collector too near tree branches or other
environmental factors.
If you are installing the CCU4 collector on a wood pole without an existing davit you can install
a davit using the Itron CCU Upsweep Davit Kit or the Itron CCU Downsweep Davit Kit. The
upsweep and downsweep davit kits each contain a bracket with a davit and arm welded to it.
The davit arm protrudes away from the bracket either up (upsweep kit) or down (downsweep kit).
Choose between the upsweep or downsweep kit to provide the collector with clearance from
other equipment attached to the pole and from nearby tree branches or other environmental
factors.
The davit kit attaches to the wood pole with a long bolt that goes through the pole and a lag bolt
that goes into the pole. The bolts and washers required to install the davit are not included in the
kit, since the length of the longer bolt varies depending on the thickness of the pole.
Required Tools and Hardware
You need the following tools and hardware to install the upsweep or downsweep davit kit on a
wood pole:
• 1/2-inch diameter bolt long enough to insert completely through the wood pole
• 1/2-inch diameter lag bolt
• 1/2-inch diameter washer, lock washer, and nut
• Drill with 1/2-inch diameter drill bit
• Nut driver, wrench, or ratchet-wrench
To Attach a Davit to a Wood Pole
1. Place the support arm against the pole and mark the position of the top slotted hole.
2. Drill a hole through the pole at the marked position.
3. Insert a bolt through the pole so that it protrudes 1/2 inch out the other side.
4. Insert the washer, lock washer, and nut onto the protruding tip of the through-bolt, and
tighten the nut until the bracket is held in place.
5. Slip the slotted hole of the bracket over the head of the through-bolt, and slide the bracket
down so that the head of the through-bolt is captured in the slot.
6. Insert the lag bolt through the bottom hole of the bracket and into the pole.
