Any one have any good ideas on how to rig up a pressure washer on my 02 Schwing 32 M. It has a roller pump now. When you switch the on knob down the hydraulics load up like there might be an auxiliary circuit. The hose works fine but a built in pressure washer would sure be nice.

Much cheaper

I've got one of those. I was thinking of maybe mounting it on the side. or down by the frame.                                      It would be nice to have on the job. So i could clean on their time..

try it on air

The built in pressure washer gets his hydr. power at the same port as the water pump, but there is an extra valve in between which is regulated electricaly whether to wash or to pump. The auxilary thing you might be talking about is normaly the compressor port.

We fit hydraulic water blasters to 90% of Transcrete pumps. You need 2,500 psi and 20 cc hydraulic motor to develop 20 cc flow of water at 2,000 psi. A pressure loss can be found depending on the concrete pump circuit.

and the cost USD ?

Thats a nice little unit Digger. Casse i think your right about the compressor. I wonder what the compressor option would be for? and if i could tap into it for a feed. They sell water pressure pumps on Ebay most have 7/8" shaft drive. Just think how clean my pump would be. Not all Grey.

CaSsE I know of at least one unit in our fleet, that had a manual hydrolic switch between waterpump and pressure washer. in that case you just have to split the hydrolic line to the waterpump. it was a 04- 45meter unit. 

Well, the compressor option is, surprise, for a hydr. powered compressor :D so you dont have to use the trucks seperated air, which is only ~8bar and not for long time use. I dont know the exact differences between both hydr. ports, i ve just put them together ;-)

Doofer, still, both things are connected to the same hydr. Port. Just the switch is done different? Still something i ve never built that way, maybe after market attached?

Its pretty hard to discribe something technically in english for me, german would be way easier :Ddd

If you split routed the hydraulic line you could run a separate motor. They sell complete units for around $1700. You could buy the motor and pump separate for around $600. Or some how pulley or gear change off the roller pump motor? I may just weld up a shelf to hold my gas pressure washer. 

Brian, if you use the compressor port to run the pressure washer, make sure it is rated for the flow, otherwise you will be replacing the pressure washer fairly regularly;

Yeah if a guy were to put your own hydraulic motor and 3000 psi water pump together some how it would have to be calibrated to the proper speed, Hp, and flow. 

Doesn't Schwing come with a factory pressure washers on some models? I wonder what they do to accommodate both roller pump and pressure pump?

Schwing has optinal hp washers on 52M's and up, mounted on the inside of the o/r; these trucks have the Hawe-handvalve; I have not seen any pressure washer on a pump smaller than the 52M (and the Apitech handvavlve); Schwing used to offer a retrofit for a pressure washer, check with them,it may not be  anymore

Many, had the best and most simplistic idea here for you B-alto. There inexpensive and easy to mount to your pump, I dont quite understand why you would even want the expense of a hyd. water pressure pump retro fitted to your machine ? It honestly wont bring you any more cash when and if you sell the boom. Just go to Northern hydraulics and purchase a new power washer, remove the wheels and stand and mount it on the pump in a nice location. take a couple of hours labor and your off and running and making money and your truck with sparkle like new after the wash is done. All for less than a grand and a couple beers.

Yep probably right. I just thought i'd explore the market and see if anyone was running a built in pressure cleaning system.

Am I runnig the only 39x (1999)to come from the factory with a power washer and no HYPO ROLLER ? I think are 39 is the second one going buy the serial number. Anyway no hypo just has a comet pump with a parker hyd motor. Took awhile to to get use to but I love the set up. I have to use a pressure hose with it and turn regulator down to keep from blowing up the standard hose nozzle . Works like a charm with no issues and going strong since new. When things get tuff on a wash out I just turn up the pressure pop the wand on and call it a day.

Thats interesting. It would be great to have both, maybe even a soap injection. I could just remove my roller pump and install a pressure but i need the volume. thanks for sharing that info. I've seen them before but didn't pay attention at the time.

Brian, a separate gas powered pressure washer would be an asset.  You could rig up a blow-out cap to clear system and avoid a boom party in case of engine or hydraulic failure.  Putz also advertizes that their pressure washers can be used to power the hydraulic system to fold the boom and retract the outriggers in case of failure too.  OPf course, the plumbing has to be proper and the water flushed from the p-washer so that you have cleran oil.  It may be slow, but it works in a pinch.

Make it quickly and easily removable from a convenient spot on the pump.  Gas needs to be refilled and oil changed.  The pull-cord needs to be located so that it is not a huge pain in the ass to start.  Must use good filtration on the pump intake to keep nasties out of the delicate parts of the high-pressure pump.  Some p-washer pumps don't do well without a little bit of pressure on the water feed, whether by having some gravity head or a 12 volt pony pump to boost it some.

Thanks Speedy, or Doug, boy I miss having  Good mechanical pumpers around to talk crazy ideas with. NO offense you guys, just don't be afraid to speak up.

Likewise, Brian....

Running a hydraulic system in an emergency case with a pressure washer pumping oil, would be incredible. 

Don't over engineer simple "kiss"

We mounted 2 or 3 on pumps (older 32m's) from the powers to be.It was clearly a joke as the washers were way smarter than the operators.After a few months they were back being taken off.Use the basic tricks one learned when taught,plastic,oil cans and elbow grease,hand wash.I will say it's tough in the winter with so many using magcloride on the roads.

Yeah Many, Maybe i should change this topic to "How to Clean Your Pump". Ha. 

Simple, not quite. 7 years in and I'm still learning.
