pictures to share #2

[oakland]

heres a few pictures i thought i would share from the last few weeks. couple different jobs a couple different mills. enjoy the pics guys.

[oakland]

few more of the 450

do you check your teeth each day?:beatsme

[griz]

hot time

[oakland]

what happened to that last one? i like the new RX900 it looks SWEET!:D

[milling_drum]

Have to take a stab at it but....that burnt machine looks like Fleet Millings RX700 that burnt in the cut in Manhatten, New York City last year.

Thanks for all the pictures Griz, good to have you around:)

Also, its good to see that Garrity are buying Roadtecs these days, I was in their yard in 2005 and all they had were CAT and and a few CMI machines. I know they had a W1200f too.

[griz]

#1 rx60c, #2 armed guards at airport, #3 rush hour down town, no beavers ?:beatsme

[milling_drum]

hot time

I was told that machine was loaded Thursday and sent to a company in Florida called Turtle milling, they actually bought it.

It had less than 700 hours on it at the time it burnt up. If we were to answer the question about what happened, peoples feelings would be hurt:)

[milling_drum]

Man, I gotta know who owns those RX900's and would run them in the city in tandem, thats allot of cutting power in one place. I'd be over there in a second if they needed help:)

its not valentine :( even though they own a few, its a company out of utah

http://www.coughlincompany.com/aboutUs/

they have quite a history if you read about them.

[milling_drum]

Thanks for that Info Oakland, when I finally get a phone that ISN'T mixed up with Nextel I'll have service and give them a call. The website was a good read.

I noticed above that the dudes from Barcelona have the grade control box wire running directly to the sensor box control...its like a bypass, I've done that with a few Wirtgens.

[milling_drum]

do you check your teeth each day?:beatsme

Why anyone would run that to that level of disrepair is quite simply stupid.

[milling_drum]

Here we go...some recent stuff.

[changexlt]

Some of that looks oddly familiair. :thumbsup

[oakland]

great pics i sure do love those older cats! here are two i have seen recently.

[milling_drum]

Believe the read out on the CAT dash...it sez the autos are on and we are moving along at 99 ft per min. The RPM gauge shows that what we are cutting isn't into the motor at all.

[milling_drum]

Guess I can cut straight sometimes after all:)

[nevole]

Looks like Goodridge Mn

[milling_drum]

Thats at the cutoff into Hot Springs, South Dakota. Hwy 79 and 18. That range in the background is the beginning of the Black Hills.

[nevole]

The Minnesota Highway 219 and the Thief River Falls signs in the earler pictures has to be near Goodridge as 219 is only about 15 miles long. Sure looks like home to me!!!

[milling_drum]

Exactly right. That other dude that posts pictures here, changelxt is in Thief River Falls today actually.

[changexlt]

I remembered to take a few pictures again. What i've been doing this past week.

[changexlt]

Also hauling this beast, and watching for metal, along with measureing.

[milling_drum]

My phone takes awful pictures...

[oakland]

great pics everyone. sure is strange to see how profilers are hauled in different areas. here the conveyor is always hanging off the back of the lowboy versus torwards the cab :beatsme

[Buster F]

The only time we load our machines with the conveyor facing out over the cab is if we are going to be working in an area where it's not possible to turn it around (such as a live interstate). We have in the past run into height issues using this method (not to mention a few damaged exhaust stacks:D)

[milling_drum]

In many cases theres a clearance issue. Some machines won't make it onto some trailer decks with the boom off the back, CAT/older Roadtec's have a conveyor support for the upper conveyor that runs across the lower front end of the frame. Depending on the trailer, you can only load them with the boom in a certain direction. Also are the add on's, some folks are bolting tool boxes on that reduce clearance too.

[changexlt]

Somebody didn't like the camera too well.

[milling_drum]

Dude, at least they had the machine set down fairly level for a change...

:)

[milling_drum]

Montana, just outside Bozeman.

[milling_drum]

Some of Changexlt's friends:)

[milling_drum]

Missed these two up there^

[changexlt]

I don't think I'll be hauling or operating that stuff, anymore. Or I hope not.

[milling_drum]

But we know if I'm around IBI for an extended period of time, I'll have a few wonderful 450 days...

On Northern Improvements job at the end today...both machines are still in the cut, on the right shoulder facing each other.

[milling_drum]

Over in HK contracting's yard, a Valentine machine.

[oakland]

wow you move around alot milling_drum :D atleast your busy though that is good to see. here are a few pictures from my area, same machine two different projects.

[milling_drum]

The old rear loaders are nice to look at, but to run them is an entirely different story...even when you know what your doing.

The Western machine has hydraulic endgates, that thing did not leave the factory like that...nice modification.

[milling_drum]

This is currently sitting in Northern Improvements yard in Bismarck, ND. They tell me they ran it a few weeks ago on a county rd job. They also tell me they run a bigger model Barber Greene RX75. I'm dying to get a look at that old thing too.

We should have started an "old Iron" thread here in the mills section.

[milling_drum]

Those aren't teeth marks on that manhole lid and ring? *gasp*

[Buster F]

At least the manhole is still in the ground and not in the back of the truck(or on the hood of the truck). Nice way to save the trimmer guy some work :-)

[milling_drum]

I agree with Buster for the most part but...cutting straight over a manhole is a never a good thing....unless your groundman is good enough to handle it.

In those pictures above there was two groundmen (dolts) and they NEVER saw it. Earlier that day we hit/ran over three waterboxes /valves. (all 3 before 10 am too)

[Toegrinder]

I've hit a buried cattle guard no one knew was there on a recycling job with a pr-1000 down in AZ. needless to say we were done for the rest of the day. Had another job down in Rocky Ford, CO, we had two pr-800's doing the main hwy through town at 4". I hit 17 manholes in two weeks that had been paved over long ago and nobody decided to keep track of. what a nightmare.

[milling_drum]

Ouch....there should be clauses in resurfacing contracts which give the mill sub some leverage if that turns out to be the case. But oh well...

[milling_drum]

In Aberdeen, SD. an obvious once great milling/profiling/cold in place/reclaimation set of equipment sits rotting away.

[milling_drum]

I'll bet these things were vicious when they ran good.

[milling_drum]

Heavy artillary...is an understatement:)

[milling_drum]

Imagine having to run this stuff? Better have some gloves and plenty of patience:notworthy

[milling_drum]

.........................

[Toegrinder]

I hopped on the 1200 in the first picture on post number 48 back in 2001, my first year milling. It was definitely a beast. You can see part of the companies logo I worked for that it used to belong to, Arizona Pavement Profiling out of Phoenix. I worked with them from 01-07. It did nothing but sit in their yard for years because it was too big for most of the jobs they claimed. I always wondered where that machine went...now I know haha.

[milling_drum]

Thats excellent to read!

Its ashame it was a Sunday and no one was around to talk too. The one with the square leg barrels...(they steer too?) and whats the PTO/gearbox with the handle on it? You engage the clutch by hand? The costs of mobilization of those big machines has ended their careers, two halflane mills can outproduce them easily these days and cost much less to run.

It looked like 2 of those PR1200 mills came from Arizona Pavement Profiling. One of the other ones had an L&L logo faded of it, they are a big outfit from Michigan.

Still, I'd love to see one of them in the ground at full rip....

[Toegrinder]

yes they steer too. If we are talking about the same thing it's a pony motor you attach to the cutter drive pulley to turn the drum when you are changing teeth like on the PR1000's...makes it alot easier. It really wasn't bad pulling the drums out for transport, didn't take long at all, and we had our own transports. But the cost of permits and pilot cars didn't help much i'm sure. I never knew they had two 1200's, they must have got rid of the other one before I came.

[milling_drum]

Its nice to be in the south again in some ways...and not in others.

[milling_drum]

yup.

[milling_drum]

Shame to see them like this but its good to see the old RX40 on the trailer ready to work....

[milling_drum]

That was a PR750B? anybody know?

[milling_drum]

more..

[oakland]

I would not mind re-storing and/or loading a few of those oldies up on a low boy (especially that CAT) I would find some work for them. I have to admit that milling here has been very slow lately and i have only seen this one around.

[Toegrinder]

That was a PR750B? anybody know?

definitely a 750...never seen a 750B though...what's the diff?

[Toegrinder]

That was a PR750B? anybody know?

or it could be that I never even paid enough attention to notice if there was a B on the two 750's I ran for years haha. I'll have to look back through my pics.

[milling_drum]

Up load your pics when you get a minute.

Brutal looking things the old rear loaders are...

[Toegrinder]

I will but I need to have them scanned first, back before my dig cam days haha. They were definitely beasts, felt on top of the world

[milling_drum]

Unfortunatly...I couldn't stand much of this.

[kokosing]

Hey milling drum, in the couple of pics of the Donegal CMI and the Wirtgen, where did you get the pics from? Not too far from my house is why I ask, was/is a large rehab project along our waterfront

[milling_drum]

Ya man, those are from the Route 5 job Union Concrete is doing.

Donegal seemed to be helping them out since they couldn't have two machines running in different locations on that job.

Also, in the pictures to share thread 1, you will see a busted manhole from Orchard Park Rd, the pictured Wirtgen did that one:)

RS600 and a meter bittelli mill

[milling_drum]

Excellent Pictures Bean, Thanks.

That Old Roadtec thing belonged to a company called MSO?

Over at Facebook some of the dudes from the French version of Miller have a pretty good group going on, I may have posted some of their pictures in the older thread, they run a PR1050 as a mill for the Midland Mixer they use.

[bean]

MSO used to own them but split up and Seeley Arnill took the recycling years ago MSO took the chip seal and micro surfacing. MSO USA (owned by seeley) used them in michigan and a few other states but not for a couple of years now. MSO in canada is now owned by miller.

The RX120 the bigger of the has been parked for the last year.
The RX110 is still running and is getting major work done to it this winter.

I noticed on the french miller train they have no crusher or screendeck but they have a drum that must produce some fine material. I'm pretty sure the specs in quebec allow them to get away with that.

[milling_drum]

Or something like that.

The operator tells it that they won't allow him to run any faster than 20 ft per min...ouch.

They posted a pic of the drum, its the Wirtgen one that has tight spacing, not the fine lace spacing like a concrete drum but looks like one.

Seems like Miller has a stranglehold on an awful lot up there now, when I was up there working for them in Ontario they had just started taking over companies....EC King/Smith Construction and so on....back then they only had a PR450/Ingersoll 2200/Wirtgen DC2100 was new that year and they had two PR1000s with cold paving trains.

Now the amount of milling equipment they own is literally staggering. (between all the divisions)

[bean]

another train

[Toegrinder]

Guess it's time to dig into my pics finally

Pic 1- Waiting for traffic control and the contracor on I-70 in Glenwood canyon outside Glenwood Springs, CO

Pic 2- W1200 on wheels...9.5 tons per wheel...whoever designed that machine needs to be shot

Pic 3- Pr-800-7 with an 8.5 foot cutter just outside Phoenix with Arizona Pavement Profiling

Pic 4- Same 800

Pic 5- Running an RS650 on the same job outside of Phoenix

[Toegrinder]

Lost the gears in the pump splitter gearbox on the highway at 3 am in Durango, Co, thus lost all hydraulics except travel. Used a 980 loader to pick up the ass end out of the cut and got it off the highway. The transport company we use also has a crane division and brought out their 120 ton crane to set it on the transport, made that 2000 look like a little die cast model...unreal.

[Toegrinder]

Pic 1- Same job in Durango before the breakdown

Pic 2- Telluride, Co

Pic 3- One of our transports

[Toegrinder]

I have plenty more pics, including some that might not be allowed to be posted since they are too graphic...basically that aftermath of what the cutter can do to your foot:eek: :Banghead: :oops: :cussing:

[RonG]

Can you tell us more about the pic that you are using under your name there?Where was the camera and how did it get up there?Thanks for sharing.Ron G

[milling_drum]

Excellent Pics.....at least it wasn't leaking oil while it was up on the air:)

[bean]

Pic 2- W1200 on wheels...9.5 tons per wheel...whoever designed that machine needs to be shot
I agree they suck big time.

The canyon wall runs right along the interstate and I was feeling a little frisky so I climbed up about 100 ft and took the pic. We were sitting on the westboud side. That canyon was actually the first milling job I was ever on. We did full width both directions four inches deep, 13 miles both directions. We had two PR800's, a PR750, and a PR1000 for a couple weeks. Took us four months to do, 16 hours a day, it was an awesome job to be on. The colorado river runs right along the eastbound section and there are a few rafting companies that run river rafting tours all day everyday...good scenery if you know what I mean :D

[milling_drum]

At Miller in Atlanta we took the outer wheel off the W600 we had on shouldering applications and replaced it with an entire leg barrel that had a track (custom made) worked great. We DID have to put that wheel set up back on for rumble stripping.

I've run a few 1200F, none with the wheels, always tracks. I have run a few of the smaller Wirtgen mills with rubber wheels like that and they REALLY sucked to get on a tralier in less than ideal conditions, IE weather or worn out rubber on wheel affected steering, that kinda thing.

I was taught with those machines that have a leg that swings in so the cutter can stay close to a curb....soon as you come off the curb or out of the cut...swing it back out...do NOT travel Long distances and do NOT try to traverse the cut with the leg swung in or you may flip it if your going to fast....Wirtgens do not elevate very fast....at least the ones I've run don't.

That outift I was just at in NC, they had a W1200F which they were having all kinds of problems with. The few times I saw it in the yard on the trailer the leg was always swung in, I asked the owner why they would put it on the trailer without swinging the leg back out.....hes a good guy and had NO idea of what I just mentioned about swinging leg out....they never bothered with such things atall...hence the problems with travel and worn track pads. (oh, they blew a lowerdrive up on it once too, go figure)

Last I saw that machine on the trailer in the yard, it was in sorry shape, lower belt full of material, main cutter bearing no grease and of course...the swing leg was swung in...bet it sucks to operate after being run by people that lack a little bit of common sense.

I think the W1200F is a good machine in the track config, I couldn't even begin to imagine trying to run one with wheels....ick.

[Blue Collar]

i run a w1000f and hardly ever have the leg out unless i am cutting along a shoulder with a deep drop off, or doing road widening because the machine is narrow anyways just to keep a good cut while one side is tracking in the ditch. It doesnt really matter whether the leg is in or out, really just whatever the operator prefers

[Blue Collar]

hey toegrinder, one our w2000's had the same thing happen to it this summer up by chicago, and had to have the O'Hare wrecking company come and pick it up and put it on the lowboy. We didnt get on tv though haha

in the track configuration i am sure it is a handy machine, but not wheels that's just retarded. it's pretty reliable too, only had two significant problems with it in 3 years.

In regard to cutting along curb, I prefer to have the leg out, as it makes it easier to see the curb on the inside of the sensor/endslide. Also because when you turn away from or towards the curb the drum doesn't move as much as if the leg were to be swung in. Everyone's preference/style is different though:beatsme

[Toegrinder]

hey toegrinder, one our w2000's had the same thing happen to it this summer up by chicago, and had to have the O'Hare wrecking company come and pick it up and put it on the lowboy. We didnt get on tv though haha

That was actually the third time we lost the gearbox. The first time it was the bearing on the output shaft, tore it apart and replaced the bearing. Second time we lost three of the six gears. I tried to get the owner to let me replace all six seein as how I had the other three magnaflux and they had microscopic cracks. But since they had a pricetag of $1,600 to $3,000 each, he opted to do just the three. Ok fine:Banghead. Well the rest of the gears lasted about two weeks, destroyed all the new ones plus an old one. He wanted to replace ONLY the busted ones again, but I was finally able to talk some sense into him. Ended up paying $14,000 for a new complete gearbox. All in all though he spent $20,000 in parts, plus the time to replace it all, and the crane cost...ouch. The first time I tore the gearbox out it took me 16 hours to get it out, I can now have the gearbox out, gears replaced, and gearbox back in and running in 8 hours(with one hand tied behind my back, blindfolded, and one earplug in haha.)

[milling_drum]

Alot of the curbs out here have NO gutter pan atall so running the leg in is a certainty in alot of areas out here in the east. The one machine I mentioned earlier had all kinds of problems from travel control all the way to track pad wearing uneven. I've also seen a problem with the track motor hyd lines getting in the way during a leg swing and either being torn off or crimping the ends up badly which in turn causes the hose to split...but...

That W2000 your mentioning, those mass of problems are unusual too Wirtgen from what I've encountered, never seen bad drives or gearbox problems. I have seen plenty of leaking lowerdrives from the afforementioned issues. Gearboxes are never an easy fit.....I can only hope you had a covered area and some decent weather to do that in...

[bean]

wtf is this i think its CMI from what i can see in the photo and kinda looks like a trimmer but i'm not sure

wk construction owns it i'm pretty sure

from what ive read its an independant part of their cold in place process that picks up already sized material from a train and paves it all on its own

[Blue Collar]

Just curious if any of you guys in the north were still millin, or if the season is over and how everybody did this year compared to normal. Our season in Indiana was alright but still down from previous years. Illinois kept us paid, that state was redoing every road they got it seemed like.

[milling_drum]

Goood question.

Most of the northern mills are parked by now, asphalt plants generally shut down the second week of Oct. However down in Jersey and NYC they keep running right into the second week of Dec and DOT in NYC does not shut down at all from what I'm told.

Out where I was in the Midwest this season was good, plenty busy except towards the end there was a shortage of liquid asphalt....so they cut short a few large square yardage jobs. The southern folks are running as usual, lots of competition amongst the contractors.

Next season is supposed to be really busy, that lecture from the president reinforced that stimulus money was held back in order to keep it from being abused/wasted/stolen. Which means in short they are releasing funds in equal amounts over longer periods of time.

[Blue Collar]

hey milling drum, i know you get around to a lot different states was just wondering if ya ever worked for one of milling contractors in indiana

[Blue Collar]

i hate road widening, but i run the 3.5ft drum for our company and always get stuck milling the dirt and clay to widen the road and it pisses me off when my drum is always getting clogged up and wont kick the material onto the discharge belt. Does anyone have any tricks of the trade to share about how to keep the clay from sticking to the drum, like anything to spray on it or anything that can be done?

[bean]

no water is the only thing we found on out pulverizers/recyclers. Clay is a major pain in the ass

[Toegrinder]

That W2000 your mentioning, those mass of problems are unusual too Wirtgen from what I've encountered, never seen bad drives or gearbox problems. I have seen plenty of leaking lowerdrives from the afforementioned issues. Gearboxes are never an easy fit.....I can only hope you had a covered area and some decent weather to do that in...

Covered area..HAHA what is that?? I had a 10'X8' 1" steel plate to park it on...that's it. Wirtgens are definitely awesome machines...but only if they are properly maintained and people aren't constantly hammering anything and everything in the ground. This 2000 is an '01 with about 7,000 hours. the previous "operator" that had it since new for 6 years by no means took care of it. he even let the four main bolts that bolt the cutter housing in fall out and eventually the cutter fell out when he was milling. tweaked the whole frame of the machine. one of the ears where the gearbox bolts to the frame broke. I am constantly tightening the turbo mounting bolts..electrical problems at least three times a week. although this machine is a nightmare to keep running, I am kind of glad because I now know it completely inside and out, electrical and all.:bash

[Blue Collar]

Thanks bean, i know what you mean thats about all that can be done. Just wish i could pound that through some contractors heads when they complain about not getting enough distance or square yardage for the day. The worst time i had this summer was when it rained 1.5" on sunday and i was supposed to finish the job that monday and i told the company we needed to work the saturday before and finish, Long story short one more work day turned into two and half

[milling_drum]

I just effin wish I could get into Indiana, the pay rates are great. But the upper plains are aight for now:)

You could try to modify that drum a little for shouldering? Bean mentions water and thats about all I would be inclined to believe would help. However more water would make the material heavier and cause problems with the lower conveyor unless you control it carefully on starts and stops...extra paddles on the drum might help but slow you down milling....In effect they should always have a special drum for that type of shouldering if clay is going to be a problem...eventually it will cause you a break down...as it is its costing you time cleaning it off....widening does suck.

That Wirtgen W2000.....I've been of the impression that Wirtgen make a machine thats so easy to run that the people running them ignore...or never know certain/somethings because the machine does it all. For instance, you can take a person thats only run Wirtgen for 5 years and send them with a CMI/Roadtec in a three track config....they are completely lost to set it down, they have NO idea where or what zero is or how to walk the rear track over a manhole....this issue is endless...Good to see you got the know how with the Wirtgen electronics....that is by no means easy either.

[milling_drum]

While I was in Atlanta I dropped by The Miller Groups yard there. Spent a number of good years with them running most all of the machines pictured. The reason these machines are in the yard is because they mainly run Wirtgen now....CMI is pretty much a thing of the past.

Found these kicking around the net whilest lookin for work...

[milling_drum]

In post 100, behind the PR1050 on the ground, anybody know what that is?

[milling_drum]

off they're website.

[Turtle]

Burnt mill is 'was Fleets RX-700. We bought it for parts last year from Charlie at Mohawk

[milling_drum]

Mr Ando, I saw those mills while they were running, they weren't taken care of very well and that happening was just a matter of time.

One day over at there yard they had a 60B on the lowboy ready to take it to a job, I was giving it a look and noticed that the bearing on the drum was shot. I told them about it while I was in the office and they seemed to not care. It went to the Conduit expressway which isn't far from where I was staying in Queens NYC. Couple of days later I saw the milling pattern and a huge stain of oil on the road. Apparently it lasted about 15 minutes running and for some reason the protection shaft into the planetary held together long enough to do some damage on that side as well.

Like alot of the milling contractors that don't take care of their mills, they are gone.

[Turtle]

Here's a few pictures form our archives at Turtle Southeast.
1) 1974 Galion RP-30, 30" head no conveyor, no grade controls. Ground man directed operator up or down for depth of cut.
2)1976 CMI PR-575, 9'-3" wide cutter, rear load, extra engine mounted in front of machine to give extra boost to cutter drum hydraulic motors
3) 1979 Roconeco Sidewinder 6.5, first direct drum drive, front load mill, invented by Herb jacobs in his barn in Taylor, SC, His company was bought out by Ingersoll Rand and machines we called MT or MW 6520's. Same basic design is used on all half lane mills today.

[milling_drum]

Just to have someone around thats been milling that long is incredible. Thank you for the pictures and PLEASE post all you are comfortable with sharing.
