You no longer need to climb a ladder get the job done. Dig a hole with a dimension of 80 x 80 x 80 cm. Build a metal cube with dimension 60 x 60 x 60 cm using 12x 80cm x10mm steel rods.Make a card board with 8 holes matching the metal base. Fill the hole with 10 cm of concrete and put the 60 cm metal cube in the center. Stabilize the 8 anchor bolts into the hole with the card board we made in step 4, make sure the threaded part of the bolts is protruding above ground level. Continue filling the hole with concrete for 15 cm. Build a number sign "#" with 4x 80cm x 10mm steel rod, the square of the number sign should measure 30 x 30 cm and should be at the center. Stick 4x 80cm x 10mm metal rod vertically at the corners of the 30 x 30 square. Make sure these rods do not stick out above ground by hammering them down.
Continue filling 30cm of concrete. Build a 2nd 30 x 30cm number sign "#".
Fill up concrete until level with ground. Wait 2 weeks for the concrete to dry (actual wait time will depend on the grade of your concrete). Place the base on the surface of the concrete foundation, with the end of 8 anchor bolts going thru the base. Secure the base to the 8 anchor bolts with washers and hex nuts.Spray some anti-rust when you have the tower, turbine and everything installed at the end of project. Why do I have to build metal frame (cube) with steel rods? The metal rods are to reinforce the concrete.
Without these rods, your foundation will be very brittle and will not last long. I don't have enough space, can I dig a smaller hole? Yes, in the above demo pictures, our foundation is not 80cm cubed.It is 100 x 50 x 50 cm. You just need to scale you metal frame accordingly. Precisely 74.5mm (around 2 1/2 inches). Southwest Windpower Air-X GreenergyStar Phoenix, MegaShark requires our tower adapter.
