Wind Farm work is gonna be HUGE the next 15 yrs they say. 3000% more they estimate.
All fine and dandy for the people who lease their land but, it divides neighbors and towns. A sad thing really.

It's funny , i was just about to make a joke about , i hope the UFO's don't knock it out like they supposedly did in England a couple of weeks ago . Then i saw the round image in the first photo on the left hand side , due due due due :D .
lol i was gonna say thats just a plane cause the airport thats in rhode island is a little more to the left in that picture and planes are always flying over the area, BUT now thats its enlarged im unsure

all fine and dandy till you want your land back or till the gavernment determines it to be the property of the power company.

I did some windmill foundations early in this industry. Been against them since 1988.
Some educational information. I know they do provide some income for a few workers, But there is better sources of reliable power out there.
Windmills can't operate with out subsides. This could very well be the highest priced electricity I used to have over 7,000 next to me, now around 5500. Interested in the environmental damage, I live in the largest golden eagle breeding ground in the world. Even the protected eagle is killed here without a fine since 1981. Interested still go to http://www.darrylmueller.com/alarm.html
This is what the wind does to some windmills.

4 Guy wires would prevent all that damage .

Don't they have some sort of furling to turn them out of high winds ?

The ones I have been around have a mechanisim that stops the blades when wind is at unsafe speeds. These fail from time to time. When the fail, you see what happens to them in previous pictures.

The big problem around here is the blades being struck by lightning. The repair requires a crane to swing a man basket. They sand the blade, put a new coat of a fiberglass type process. Then its a waiting time for the epoxy to cure. This depends on temps. So they all wander off, usually to local dinning establishment. Once the epoxy is cured, they sand the blade, and it goes back into service.

Im not sure on subsides. When I was out in Oregon last year, the guys from the local power company were telling me each windmill cost them 2 million dollars. On average, the investment was returned in 2 years. Average life on each turbine is estimated to be 20 years.

Very nice looking crane. I live in So. Cali about 2 hours from the palm springs, CA. wind mills and have been there to watch a few put up. very impressive and yeah when they fall, they tend to make a mess.

I am real sure on subsides, it called: production tax credits, carbon offsets and paying more for wind generated power than other conventional sources and other scams. FLP does not have to generate any power, there is so many tax breaks out there because of government programs that support alternitive energy. I will dig up some Palm Springs erection pictures I took several years back. You will be shocked at the size before they are lifted in place.

These are big guys around 380 ft. top of tip. each blade around 75-80 ft. long look at the ones on the ground that have not been lifted in place. They put 2 blades on and lift it in place and install the last blade. I was looking for a picture of the crane next to it the windmill house is the size of the crane house, can't find it I remember seeing it and was shocked at the size. This is the highest price power, and it only runs when the wind blows, the power grid has to have power plants ready to take over the load. Here at Altamont Pass there is only a 20% maximum run time in 24 hrs. During the brown outs the windmills did not run here if that block was turned off, they need power to energize them to rotate on the start up mode. Oh yes I forgot these are imported to from Japan, Denmark, and other non USA sources. Taken 3/29/01 in Palm Springs.

I think that may be an LTM 1500 Liebherr.... or the older AC1600/ AC650 Demag ... hard to say without closer shots of the upper work's ...nice unit ..whats the name of the company on the boom ..

the wall starts when an agreement is met and parts are ordered and they the citizens begin to have second thought's or land owner's want more money to place them there ...Ive seen this ..the 1 million dollar price soared to almost 2.75 million installed because now there was a two year delay in erection ,the parts had to be stored and maintained ...yes even setting on the ground in wait they needed constant maintainence ..more so than if they were in service ....

Windmills have there pro's and con's ..its a delveloping technology .... think about it ..at start of the nuclear age ..how many nuclear bombs were detonated around the globe ..before the yeild and data was aquired to keep reproducing without destruction... the world is there now ..(never mind that all agreed to stop testing ..the data had been aquired and whats the need to test further ..no other reason to stop other than the data was there ..)

So windmills will be a facet in green energy ,solar another facet ..and hydrogen engine's another.. the list goes on ...and so will new idea's

That's quite a crane.Allot of rigging invaulved with the jib.Vary impressive,It make's my rig look down rite simple.I can see how the weather would effect a wind tubine job in a big way.Be safe& great pic's.

it takes about 6 to eight hour's to set a machine like that up ...that would include ..if it has to be done launching the main boom ..

When there is a fire like 300 feet in the air a small rural fire co. has to just let it burn out, hot fire being blown on dry grass in remote area is a bad mix.

they spend most of the day today (sunday) taking the machine down to set up in a different spot to do the pick of the blades, not sure when they are doing that pick , next couple days are snowy and crappy and they said it needs to be 10mph or less to do it .

heres some pics from yesterday when the put the last piece of the tower on then the generater on

I was going to guess a full day to set up a rig like that,with a crew of 8 to 12 workmen,&other support unit's.I wounder what propeller weigh's.Truly impressive.

I've never been around any Hydraulic luffer cranes....I wonder if you have to boom the luffer down when scoping out? Or if you just scope out and it automatically booms it down? Like in rigging mode or something?

Some units ..you had to boom up and scope out with the luffing boom tip touched down ..that was trick because you had to keep the mast from coming over ... while scoping it usally took a few guy's taking up positions all around the crane with one duty and to give a hollar if things were not going well ..... after the crane was scoped out ...you would haul up on the luffing whinch to finish erecting the luffer...

on some more you would boom up to a predetermined boom angle ,,stand the luffer ,, and scope out.. now on some the computer will maintain luffer angle and pay out rope as required ..on others ..the operator maintains all function ..scoping ,luffer angle ,,main hoist rope out-put..and so on ..

now as in the case above ..you would have to boom up, stand the luffer , and scope out ..you have to pay out rope to the luffer ,pay out rope for the super lift (computer aid),,keep the super lift tensioned as not to pile the respective drum's(computer aid), it gets interesting at best ..... it can take upto and 45 minutes to put the crane in service ...often times its less to around 30 minutes ...do to the pinned main boom design of most newer hydro's..

Of the top of my head ..i think the hub weights about 24,000 lbs ..each feather about 6000 lbs.... when possiable the whole thing is put up hub and blades one shot..

They had to move the crane to set the hub? a mistake they wont make again...I remember hitting this wall on a wind farm ..the pads were made a little wider and the tower was laid out side by side ..base,mid, top ,using a 80 to 100t tail crane to stand them ....
the hubs were laid out to allow one blade to come back behind the tower ,, the erection crane was essentially placed in the "V" of the hub and feathers ..by doing this we were able to get the hub's 35-45 feet closer or as required by the crane..

something thats a little wacky about those mills ..that not alot of people looking in realise ...if you install the top section of tower ...you have to get the Nacel on ..you cant leave it..the tube is only truly ridgid wihen the Nacel is on and its weight apllied to the tower ... Ive seen our equipment stand for hour's waiting to get the wind right for the Nacel while holding onto or hooked up to the top section ...no sense putting it up if it has to come back down ..
the tops can weigh around 50-60,000 lb's the Nacel weight's can vary ..100-130,000 lbs..depending...

Its a Greer system... pretty much all the same just diferent software for the model of crane ..

The only thing i dont like about that system is that the A2B is a open or closed circut ..In the greer system if the boom lenght/A2B cable goes to ground the system can function and unknown to the operator the A2B can be inadvertantly over ridden ..This was the case on earlier models ...stick a piece of wire in place of the switch to see if they changed that ...its food for thought if you see fraying on the cable or dead end ..

This cant happen in a PAT ..theres a resistor in the switch ..and if the LMI does not see the exact resistance in the A2B loop, the A2B is activated..
