I'm a 35+year operator.I've run putz mostly.I was running a swang a few years back and the remote had the concrete pressure you were pumping displayed. I really liked the idea.The best thing to come out in years for safety.I had to put 5 2/1/2 in hoses on the end of the boom and could not see the hoses at all.I had delays in the mud service.But i could watch the display and see if it was going to put to much pressure to get going again.So why not a pressure shut off you can set????

Its an idea. But why would you want lower max pressure? all the hoses and system should be able to handle the 80 bar..

surely this is what you have output/volume control for , since the pressure becomes less of a problem if you have no volume behind it??

You CAN set the pressure, both accumulated concrete pressure and hydraulic pressure.
On the old ones you had to do it on the truck, but on the new ones you can do it from the remote.
Another nice feature is you can set the max concrete flow/pump speed, very good safety device to have with lines, who hasn't accidently put volume on max when walking around, dragging hoses or just snagged it with your jacket?
I know I have...

I have it to , You can have it on modern Putzmeisters if You order it.... When You have learn to use it You dont want to operate one without . It's like an air-cuff , once You started You wont go back !

What i would like to see is one you can set.Like your first load pumped out of the boom our system.Say it's 100 bar, you set it to 125. If it goes over, it trips the safety.You have time to see if something is wrong.

Ergonic for truck mounted concrete pumps

Yeah it would be nice. I've often said small line pumping should be done with small trailer pumps. 275 bar max is too much. Bammm! Who wants to go see what happened at the other end.
