Can anyone tell me why none of the "S" tube pump mfgs have created a

Valve housing + hopper set-up like Schwing? Why can't the ass-end of an 's' tube valve housing (not the valve - the 'hopper) be unbolted, alowing access to the valve?

Picture a Schwing hopper with an 's' tube valve. Zip - zip - zip and you have access to the valve.......... sweet ;~)

And while you are at it; why not split the hopper / top and bottom? Anyone that has ever had to hang like a bat to work on an 's' tube knows what I am talking about.

bob....my new 63 has half a plastic hopper so when you need to you can take it off to get to the valve...

Big step in the right direction

   yeah bob my putz 52-5 has a hard plastic top half to the hopper it takes ten minutes to take off leaving you plenty of room i even changed my spec plate and cutting ring on my own if that was the old stile hopper with a trunk you want at least two of you for the same job

Everyday i wish my pump was more like a Schwing.

That's why Schwing is the leader in concrete pumps,dependable,operator friendly,lowest maintenance costs,easier to work on,just by far the best concrete pump on the market that I've seen,and thats quite a few.

Stop holding back, tell me how you really feel.  ;~)
