We have a 45 meter schwing that will stop pumping,it will go into reverse but not forward if you unplug the vibrator it will go right back to pumping.It dont always do it it done it to me bout 2 years ago but hasnt done it again til yesterday.It has the vector system.has anyone else had this problem.I called schwing and they dont know why it does it.thanks

  when this happened did you get a chance to see what the vector said for input and output of the concrete pump?Does it just start working again or do you reboot the system.

it shows no output does not show any errors.you dont have to reboot you just unplug the vibrater and it goes to pumpin.

Elecrtical problems are so difficult. Sometimes you never really find out what was wrong. Thats why I think its so stupid to use so much computers on a concretepump. They just don't belong there! With all the water and concrete and other sh't. On the 52 schwing I drove the stupid thing started blowing his horn at least 2 or 3 times a day while there was nothing wrong. And if there really was something it was dead silent.. Really nice idea when you sit behind a desk but in the real world not so nice... The latest putz I saw has a display on the remote and you have to look at it and select your options... That is insane. How long before the display will be so scrached up you can't see anything anymore? And on my remote I never have to look down.. You just know where all the swiches are... I don't understand whats better with the new stuff... Only see disadvantages...

been seeing a couple bad wiring harness lately (bobcat loader and ford diesel truck) whats funny is the old one gets removed and not repaired, they just want to plug in the new expensive one.

toby, since you mentioned the vibrator, we had some goofy things happening to us (not your exact problem), just to find out there was a short in the cable or plug itself to the vibrator; check the box where it plugs into, is there any corrosion inside? is it blowing the fuse for the vibrator when it happens?

I would pull the vibrator, remove the plate covering where the electrical wires up to the vibrator. Odds are pretty good you have water in there shorting it out. reseal it with silicone when you put it back on.

I havent checked the box where it plugs in it could have corrosion or water in it .I will check it monday if I get time.It does not blow any fuses.I did look at the inside of the plug to see if it was corroded but it looked brand new.Thanks for all the help

Dipstick: The putz with display is very durable, been running one for 2-3 years and still as clear as the day it was new. Just keep it clean like you would do every day with the remote.
And you still got all the switches as before in the same places, the display is much nicer than have to walk back to the truck everytime you want to check temps., pressures, faults, battery, signal etc. or switch something off like the vibrator or make changes to you boom conf.
I mostly see advantages with electronics on equipment, so much easier to fault search.
But the electronics need maintenance like every other piece of equipment.

On my schwing it didn't work. That pump was brand new. I hated the computer. So many times it started blowing the horn for no reason. Verry irritating. For example: You stand on a 10th floor without elevator. You agree with the concretedriver that you will sound your horn a few times when you want him to stop filling up and close the lock on your hopper because you  have to move the pump to another location so you need to pump back to empty your boom. Than suddenly for no reason the computer starts blowing the horn.. Try to explain the concretedriver (shouting down from the 10th floor) that it wasn't you blowing the horn.

So many times I had to explain the hose man: no the truck isn't empty, the pump just thinks there is something wrong but there probbably isn't..

And than there was a serious problem once and the computer didn't say anything. It also didn't warn you for example when the hydro oil was to hot. Strange.  

And about the display... I believe it's nice to have all that info right there yes. But 2/3 years is nothing. What about after 10/15 years? But I understand there are people that love it. I just hope there will also be pumps in the future without all the fancy stuff. Remember the less stuff you put on a pump, The less can brake down.

Now i've been driving without the computer again for about 3 years and never have any problems. Had some elecr. problems but always find what it is in max 15 min. And thats a JMBH from spain! Not the most high quallity product.

It is fewer parts on a wheelbarrow that could break... Why should not concretepumps develops ? That little piece of glas You change on a break.... Go back to cable and "black&white" , no volymcontrole on the remote (but you have practice to shout to the mixers) Why have air-condition in the cab , you should stand outside and work. What car do you drive ? Not a modern one , one from late 60 to early 1970 , and I mean some euro-car now not a US-car from late 60 . Black & white TV , no DVD .... Because they could BREAK ! It is 2010 !

haha. Funny. Those things are good ofcourse. But Ive never had a customer said to me WOW this job went a lot better because you had a display on your remote that could tell you your oiltemp.  Only customers that were irritated because of all the interuptions caused by the computer.  A concretepump should first of all pump concrete.

If you had a display telling you the oiltemp. you might not have cooked the oil like you did. :D

When did I ever cook my oil? You know more than me! But I don't want to start a fight here about if its good or not to have so much sensitive equipment on a machine that is abused by nature every day. Just saying I was managing fine before. And notice I got more stress and irritation with the fancy stuff. Love the pump I drive now. Best one I've ever had.

I actually expected there would be more people that agreed with me but I guess I was wrong :-)

I personally think having a display on your remote that shows things such as pumping pressure is a HUGE safety feature, It can be difficult to hear if your machine has plugged when you are working around such things as externally mounted wall vibrators ect.... I wish I had one on my remote!!

Ok. I agree on the display. I heared my coleage say he had to go in to the menu and scroll to for exmpl switch on the vibrator or the wisp. But i guess i misunderstood.

Yes you have to scroll, but it's fast and easy and laid out with symbols like everything on a Putz.
See this link for more info

I guess i'd have to work with it to be able to give a good judgement. And I guess i'll be forced to do so in the future. Till then i am enjoing my JMBH a lot. (wich was a huge surprice for me!!!)
