I asume you mean that right rear outrigger that is way to short out!! Wow what a crazy basterd!! I admit that I do shortrigg some times but this is just plain gambling. And if you stop it at axactly 2.37.... Do you see any dunnage under that outrigger? The pressure on that one must be quite big when its shortrigged like this..

Maybe its difficult to see on the video.. Maybe he has the boom more over the front than we can see. To me it looks like he is quite much over the side in between the front and the rear rigger so that means the rear holds a lot of the weight..

And it is a lazy bastard because there is enough space to extend it full.

nope carn't see any thing wrong... everyone's wearing all the correct ppe ,all the leg's are all the way out, there's a double ended rubber..nope every thing's just fine...........that is if you want accident...what a knob  over the leg or not the working side should be all the way out...o and is that peter andre on the mixer???

WOW that is exactly how accidents happen, I wonder who Trained that operator.

Beside the short riging on the working side , why the f**k is he trying to blow up the machine when opening hes boom ?? I know some machines you have to rev a bit but fuk me that machine was on 30000 rpm opening up , maybe im stupid but I dont think you need to rev that hard while opening up! maybe im soft?

Drew AUS you are correct, It has been my experience that most units now do not need to operate at Max RPM as long as you are not expecting MAX output. Either pumping or operating the boom.

When training customers in the field and the school we discuss the relation ship of Pressure and flow.

Must of you will find it will cost you a minimum of TIME in running the boom at lower RPM but you will still have the same Power. "Unless you have an old worn out Hydraulic Pump" I am talking about healthy systems.

In the old days with Black and white controls I would drop the RPM to help smooth or slow things down.

With today’s cost on Fuel is can help to lower the RPM and still get the job done efficiently and not damage the machine.

A lot of OLD School Misconceptions are out there about what can be done with these machines.

From the Pic in the beginning of this the operator wasn’t taught how to correctly set up the unit, how can we expect him to know the rest of the details.

As to RPM ask the MFG of your pump they are the best to tell you the working ranges that will provide you the best out of your pump.

I feel a Putzmeister RPM learning Post coming in the near future. Thanks for the Idea.

Another Idea, If anyone of you Know this guy, please take time OFF LINE to ask him about this. Ignorance can be fixed, teach him in a non confronting manner what he is doing wrong, it might save a life He truly might not know the difference or the reasons for what is correct or not. I have seen the gratitude in so many faces young and old, Green and Experienced, so a little time and honest concern will go a long way to help make our industry a lot safer.

If that dosnt work I will Quote a Prominent Comedian,  “You cant fix stupid”

This is a funny subject about the RPM. I like to runn as little as possible RPM myself. Thats why I irritate myself quite much when I have to work with the putzmeisters with the system (just cant remember the name right now) that arranges the revs. The epic amount of revs it needs only to control the outriggers is just a joke. I never need almost any revs with my much cheaper spanish pumps. And specialy with the outriggers you are working so close to the machine.. Combine that to a noisy mercedes engine and you need earprotection to setup your machine. Also when unfolding the boom it revs it quite much. So that means putz (who put this system on the machine theirselfs and adjusts it) means we should give it quite some revs also while unfolding.

I am quite familiar with that system, Yes the programming operates the RPM to full under load, this system is programmed to give you max performance, so it will go to the RPM that is programmed to give you the max. It can be overridden or turned of like cruse control in your car, It is a tool. Let me give you an example. The boom speeds and outrigger times in your manual are set at Max RPM, let’s say for example 45 seconds to extend a front telescopic outrigger. If you run at a lower RPM you could expect the time to be slightly higher 55 to 60 seconds. These are Example times yours will vary. So for the cost of a few seconds you can save a little fuel. You don’t need to run full RPM to get the job done. The EOC “Ergonic Output Control” program is set for advertised speeds found in the manual. When I am training operators I will often turn EOC off for outrigger set up then back on for pumping. Unless you are late for the pour then you want it all.

Putzmeister has adjust Mine EOC , they turned down the rpm 200 , so when pumping about 1150 rpm with the volymcontrol up to 7-8. Then 1350 rpm at 8-10 on the volymcontrol , if the pump dont get enough power at 1350 I must go manualy. But that is very rarely that I need more rpm.

great advise Traveltech, I feel smarter after reading your post .

Well short rig yes , maybe I'm old and missed it but was he not inside the two front riggers pumping or just inside the front. Anyways it worked. Not good but we do short the rears allot, not that we pump over a short rig but have to raise boom strait up then turn inside work zone. I may have missed that seeing it outside the safe area. But even Concords seem 60-70% front rigger dependent. But all the rest of the video has so much wrong haha, our mixer driver would be fired on the spot for one, the operator would probably get a week off if not re trained, but different strokes for different folks wow. Something I would not post on the web. But maybe it's the customer.

Travelteck-- I know you can swich it of while driving the boom. Just ment that Putz kinda shows its ok to runn at high RPM.. If this guy was using the EOC than that explains the high RPM....

But can I also swich it of when driving the outriggers? I had the feeling that that wasn't possible but never realy tried hard enough maybe??. Ill look at it next time. That would be very nice..

You can switch it of an run manualy all the time . But if the oil is cold the EOC dont give so much rpm that it adjusted till , before the oil has working temp .

this is all I need to know about  short rigging http://www.youtube.com/watch?v=ySJrDrT8Yp8&feature=related

Dipstick, It is ok to run at full RPM as set by the factory If the oil is warm not thick as molasses, that could cause cavitation. I am writing a Post that goes into the topic, should be on soon.

Yes the EOC can be turned off at any time. The unit in the Video is a Cifa, I dont know if they have this system on the units.

alfred!!! whats up buddy?

If you want to poor real slow whit a putz you have to put of EOC other wise the rev give you the volume. and for extreemly slow there is another trick whit the rpm.

You can go in and change the setting for m/3(y/3) in the cabinet so I think the slowest My pump can pump is about 15m/3 , the fine with this is that the volymcontroll is more sensitive . If I want to change 100 liter/minut it will do that , and You can lower the max pressuer if You use 1.5" hose with 40 bar .
