Dropping a Loaded Tanker

We do it quite often. Dump the trailer suspension and tractor suspension before unhooking. That's about all you can do

 

Drop it lightly on level ground! making sure the legs are as far down as they will go to not seem as if it is being dropped on them. The dropping all that weight is what is bad on them, they are built to handle the weight just not being dropped on it. Enjoy the Forum, There is plenty of knowledge to be had here!. If you have any questions, feel free to ask, I don't know much but what I know is what I know!

 

My company will not drop a loaded tanker without a wrecker supporting it… So needless to say, we only drop a loaded trailer if a truck breaks, and can have another tractor back under...

 

Being a gas hauler I have a different question. Is it just cement or mixed concrete? If it's concrete, what do you do with the concrete? Is the trailer only there for a little while? Coming out of the Navy Seabees I was involved in a lot of pours and I would question the integrity of the mud. If it's just cement and you're waiting to blow it off why would it be different than any other load? We've dropped loaded gasoline trailers before and there's no concern at all.

 

Drop it on dirt. Landing gear will hold it. Drop it on concrete is best. Don't forget those little hoses.

 

O , For those that should not be pulling a tanker anyway. Let the load stop moving before you pull out from it. 10:00 is Best. 5 minutes is good.

 

Don't think a loaded cement tanker is going to have much surge to it

 

I'm not the OP but can assure you it's not concrete mix or any grout slurry.
Once the cement powder in concrete or grout hyrates (mixes with water), the clock is ticking, and it typically is unusable once it is 2 to 3 hrs old, max.
Certain admixtures can extend this time, but not by a great deal. If you try to use it beyond it's "freshness", it will only result in microcracking, poor bond, and many other severe negatives, even at early stages of "staleness".

 

That's what I though. Just like asphalt you've got so much time and rpm's on the mix. We would allow a 6" slump if we were training with new guys and it was only a sidewalk but when we had very strict pours sometimes with a 7500 psi strength we watched it very closely. Like a runway, but then we were using our slip form paver and if it got put down wrong it came back up. It was all for training in case of war.
