More expansion work at our plant.

That is a big lift...JLG 1250AJP...125' height. I've used that model at a previous job...when you start pulling on 3' long wrenches with all your might 150' off the ground (we had the machine parked on an embankment) and the basket starts swaying back n forth 2-3', it takes a lil gettin used to! They sure make life easier/safer for those ironworkers though!
That's not a cheap one to rent either...part of the reason is pickup/delivery costs more due to the machine weighing 44k (that's a lil more than the average truck can legally haul) so the driver said they either have to get the overweight permit, or take their chances and go "the long way around" which takes them around the area where the DOT guys like to hang out.
IIRC it was a "wide load" too, even with the axles fully retracted.
You got some good pics!

 

Thank, brother ...
Several years ago, I looked into renting a 100' lift for a tree job in our yard...
About $1200/day...
Decided right quick to let the guy who quoted us about $700 to do it...

 

Walked over to the other building site...
They have started putting in the ground anchors...

 

Another reason for the calciner rebuild...on the top 3 decks, more moisture is present, burners start on deck #4.
The arms get holes in them...under the insulation wrap...


This is what new arms look like...
Crane was taking some arms out this morning

 

I didn't get a chance to go outside much Thursday, but I was able to watch them start cutting the shell into sections on one of the camera screens...
Using torches and grinders
Got it loose and the crane is holding it
Went outside for a quick picture, up and away...

 

I was on my 7 days off last week, they have really gotten a lot done...
The shel has been taken down to the bottom floor...
It was still in good shape, so it's been cleaned out and sand blasted
Sure looks different in the building now...
The main dust collector has been taken down and replaced
Way up there is the new one...
They are building and casting the big new burners on site...
Burner rings
Welded studs in to hold castable.
Completed burner...

 

Any pics of the dust collector blower?
Always interested in pics of fans, blowers, pumps, compressors and such.

 

A fan we use...

 

The fan for the dust collector above...
One of the fuller pumps we use to move products...

Blower for that type pump
2 big fans we use to move product from heat exchanger to dust collector on top of 100' silo...
Cooling air fans, cools products in heat exchangers...
One of our air compressor rooms...
Vacuum pump used for pulling products through heat exchangers from calciner
One of our mills for grinding products
Big Hoffman type blower...

 

Awesome!! Thanks T.Jeff Veal , I really miss working in large plants. The two New York blowers in series is not something that you see every day.

 

We also use that setup on another calciner system we run.

 

This steel crew is no joke, had a cold rain most of the day, drizzling to steady...
Already got a complete section installed today, that is 2 hearth floors
More sections sitting outside, waiting to be installed

 

When everything goes correctly, those prefab sections go up quick!

 

A little update...
Last week, they got the shell finished, center shaft reinstalled and platform across the top on...
This week, they finished the roof structure and got panels back on...
Moved big crane to other side, will be installing duct work to new collector
Furnace crew has started putting walls up
And pouring the center shaft castible

 

The hearths are being built now.
The form is built...
And the bricks are laid. Floor is on an angle and becomes self supporting.
This is called a in- hearth, product is moved from edge towards center, where it drops through big opening to next floor down. That is one arm, laying on the floor.each deck has 4 arms, with rakes that move product in direction it needs to go.
Forms have been moved, starting on the out-hearth next...
The out-hearth has these openings around the outside edge of the floor, product falls to next floor below.
I'll get more pictures when I go back to work

 

They have gotten more work done on the calciner.
Insulation in the burner tube
Form for burner tube installed
Another view, this is an out-hearth
Good view of how it's made to keep product from dropping to next floor around center shaft.
Drop thru holes in an out-hearth
