Bought this used 32 meter schwing in march...on this pour, with this set up (pic was taken before outriggers were fully extened)

With the  boom fully  extended and concrete moving through the sytem, the right front outrigger kept lifting of the ground three to four inches.

On other jobs with similar setup, same problem... any suggestions would be appreciated. ..ty

That is not an X frame, so it will flex and twist a bit. I assume you are working over the drivers side and the front passengers side outriggger is coming off the ground.  You could get the frame of the pump checked out for peace of mind. Just put down the passenger side outrigger so the pump doesn't rock and keep on pumping.  Sorry on real help

Had that on that size pump often. I just unfold the boom and check the outriggers after first load. Just put down the one that hangs in the air or maybe the one on oposite side if that looks better. (right front/left rear)

start first lifting on level with both front outriggers and than put rear outriggers on grund ,leveled. maybe it works for you too

Thanks for replies...level ground has been hard to find lately...which brings up another question...what is the most "out of level" to call acceptable/safe..have been told 3% but that sometimes hard no matter how much donnage is used.

I used to run a putz 32 meter with the short back legs when i was working over the back the front outrigger would always come off the ground about 6-8" 32m is the top end of being on a 28 meter footprint it wont go anywhere but i would always watch it very closely when I would operate. Your not doing anything wrong its just how it is. Get as close to 3% as you can so long as the bubble breaks the 3% line you'll be good

I've ran pumps with those same out riggers for many years. Everything from a 28 up to a 41 meter. To be honest its the nature of the beast to have some out rigger bounce on the oppiste side your pumping on.

 

I actually thought Putz said it was normall to have up to a foot of out rigger bounce on the oppisite side. Maybe someone could correct me on that, but I thought I read that in a old 1988 putz operators manuel.

 

When I would be pumping flat out on one side of the pump. I used to place the out riggers down on the side I would NOT be pumping on first. Then set the out riggers for the side you ARE pumping on. So, you can raise that side of the pump up more. Not alot just a few inches. You will have to play around with it. Good luck

I always do what gaby says.. First level the front.. Wheels slightly touching the ground. Then the back.

I drove a 33m JMBH which is the same as a 33m Concord or Junjin I believe.. Mounted on a 3-axel MAN chassis. Now that was an insane pump! I realy though it was gona tip once. Had the boom flat out over the side and pumping hard. The opposite side front outrigger was 2 feet in the air! I turned down the volume and was stressing all the time. Later the regular operator said that was normal..  

I also drive a 33m SARAKA combi pump that has the same problem.

32m Schwing that I drove long time ago (my first pump) Same problem..

Maybe it would be better to build 32-33m range on the x frame instead of sliding rear outriggers.. I don't know but its realy that size pumps I always have these problems with..

Its not realy a problem though.. The never fall over and are even reasonable stable. If you just put down the leg that hangs in the air your OK Cool

I made it a habbit to stretch the boom all the way out the direction I am pouring and chack the out riggers.   But even at times they will still come up a hair.

most of the time if you preload the outriggers quite a bit, front tires off the ground, it will not sink down anymore. you have to just be observant of the ground conditions before setting the pump up. I always pre load all my outriggers.. push the outriggers down until the tires come off the ground and the pads don't sink any. if they sink, put more dunnage under them until they sink no more

Outriggers Float: It's the nature of the beast! You can't preload for ALL positions! There's too much engineered flex in the frames, like in the booms. Without it you have breakage. I set my fronts (38m) so most of the weights is off, and then lift the rears about the same; adjust when nessesary!  Bigger booms (52 ups) I set the rear level crossways and lift the front axle off the ground, depending on the stretch, I might lift the two fronts!
