HEY GUYS, HAVENT DONE THIS IN YEARS BUT--I HAVE 40 YARDS FOR A HOUSE AT 6 a.m. and then 200 at 7:30 about 20-25 minute drive away. Any-one see a problem driving that for without cleaning out?  Yes I'll suck back a ball.

  Ran a Thompson 875 20 years ago a did it all the time. you just droped the hose in the hopper, if thought you needed to just stoped and cycled her. 

 Dont expect a problem but.. should I  suck the  ball all the way back so gravel cant settle to bottom of pipes?       Input appreciated.   I dont usualy set myself this type of scedule.

I think it is against the manufactures recommendations. Voids warranty I think?

I know that the suspension was not designed to carry that much weight or so I have been told. It is good to have so much work but maybe a little more caution would allow you to make more profits in the long run. (do I sound Chinese?)

The truck is not designed to haul concrete, heavy fines in California make it illegal. like Todd said some pumps it voids the warranty.out here its against osha I believe. I never trust mud ....!  sure some plastesizer or sugar but can you get it up into those material cylinders.... thats a no no out west here. San Francisco has even added a new law if any concrete is spilled from a mixer or any sort of pump the fine 10k misdemeanor charge... do the right thing just wash her out. just my 2 cents worth

OE-3

I KNOW....I KNOW.... JUST FRUSTRATED RAIN WAS PREDICTED TODAY-- TOLD THE HOUSE JOB TO GO TODAY HE WAS AFRAID, DID IT RAIN??   NO...  THE OTHER (200) WAS FOR THURS, NOW THURS RAIN 40% SO THEY MOVED UP. THEY ALSO FAILED INSPECT ON ANOTHER JO SO SCHEDULE CHANGED..  ITS NEVER EASY FOR THE OWNER/OPERATOR.. FEAST OR FAMEN...    HEY TODD HOW ABOUT SPELL CHECKER PROGRAM FOR POSTS.

Ok i will look into spell checker.

I just wanted to say that you don’t often get in trouble for what is beyond your control, its the things you can control and you don’t that gets you in trouble. I find i get away with nothing in life.

Probably what you are asking about happens far more frequently than is admitted in this public forum.    

I have done it. 

I would blow all the mud possible out, then suck sponge back to hopper. I run a 32m and with the bit of mud in the hopper, the drive axles of truck still carrying less weight than average 38m or 42m.  Don't have a wreck or you will spill some concrete, and then have to answer some embarrasing questions.

Just suck it back and go! At the most a half yard (2000lbs) is hardly noticable. I do it on a daily basis. Just make sure you leave enough to recirculate when you get to your next job, but not so much that you would spill. Don't cross any scales on the way. That would not be good.

How could this void your warranty? If something should go wrong with the drive train are you going to tell the manufacturer that you haul concrete around all the time.

I am sorry but I do not see any up-side to doing this. Sure, years ago when we were running pumps with pony motors it [sort of] made sense. If the mud set-up in the pump it was not good, but it wasn't the disaster it is today. You could pop the doors off of the flapper box and chip out the 36" long cylinders. Picture that with an 's' tube and 83" stroke................. not fun at all. And if you splash a car [ you know it will be a Benz' with paper plates]. There is really no reason to do this. It is not at all in your best interest.

a. You get paid to wash out

b. You get paid to wash out

c. Did I mention that you get PAID to wash out?

Why take the chance? What is the up-side? If you must hurry from job to job; dump the hopper and don't wash out. Carrying that extra 2 or 3 thousand pounds probably won't hurt your truck but why even do it? I would guess that when you are running late for your second or third job of the day that the fault is not yours. Either the mud was slow or the inspector hadn't signed off on the pour or the finishers didn't show up on time.................... something out of your control, not your problem. Don't invite problems to follow you to the next job. Wash them out and leave them.
