@garycook5125 The calculation of the load and potential forces exercised on the slab in combination with the concrete mix used showed this was not necessary in this particular case. My first tower on another site stood on a similar slab for 30 years without any problem. This one is still going strong after 12 😉

This project is nearly a decade old so any pricing would no longer be relevant because of labour/material prices that have risen. Additionally, there are many variables to be taken into account: height of the tower, new or second hand, willingness/capability to do the ground works yourself (or not), dependency upon concrete pump and/or crane and possible local community taxes for the delivery of the construction permit (when applicable) ... Please plan the project carefully and get in touch with the stakeholders and/or a general contractor who can carry out the project on your behalf. I am sure they will be ready to make you a detailed proposal.

Hi Ed, thanks! The concrete base is 1,80 m x1,80 m x1,80 m. This works out to hold about 6 m3 of concrete. The ground is heavy clay so this construction is not going anywhere :-)

3 sections of 23 feet (7 m) for a total of 59 feet (18m) of useable height

It has been custom made by De Kerf, one of Belgium's most renowned tower builders, pylonendekerf.com/ (web site is in dutch only unfortunately)

I installed the Optibeam OB13-6 myself, NN4ZZ's tiltplate easily allows this :-)

Thank you.... been to Belgium a few times... loved it! Thanks!

Well spotted! Actually they made a calculation mistake hence they needed to loosen one of the supporting arms, this is what you see in the video. Since I was not actually very happy with this, they did some re-engineering which resulted in the complete replacement of the supporting structure (using a larger steel beam and supporting arms) which was installed at their expense. The whole thing is rock solid now and able to cope with the forces when tilting down a fully loaded tower.

I thought I saw smoke coming out of something..

No, that winching mechanism for the tilting action is manual anyway (the one for extending the tower is motorized). It was rather cold and wet that day, you may have seen some sweat/water evaporation LOL

LOL, just supporting one of Belgium's top artists

Actually, its good! Makes a good break from Dave Tipper! Who is the artist?

yea its good.

Hi Ken, I guess I indeed cut off a little too quick, thank you for highlighting this, never noticed it though (editors fatigue I guess) - 73's

Didn't mean to nitpick, but I operate CW most of the time. Perhaps we'll see each other on the bands sometime. 73.

+Q Jones hi Jones it looks like a aluma tower google aluma tower

+w8mpx wow. I had forgot that i commented on this. Thanks for the reply. I will give it a look. Thanks.

Hi Theo, this may be so in the US however things in Belgium are different :-)

Hi Kevin, I put in this cores (actually constructed out of about a foot of heavy thick wall pvc pipe filoled with concrete) for two reasons: 1. To ensure the positioning of the steel construction (which you can see in the video) to which to bolts securing the tower base are attached were perfectly level 2. To secure the steel construction (part of it was cemented in) to prevent it from moving when pouring the concrete. The wooden planks also serve the same purpose.

Not so in Belgium. Apart from being subject of a long administrative process in which the neighbors are automatically involved, a detailed case has to be made available to the public for consultation.

I believe those are for the coax and wires to keep them out of the way when it goes up and down. 73s

Im guessing by now the sun has made them very brittle

Is that a serious question?
