This is correct. Before we used the curved pipe on top of the tank, we had a different set-up that was subjected to freezing shut in the cold winter temperatures. Remember that I said I hauled spring water. If the temperature was below 30, they wanted us to open the dome, and bypass the vent pipe, and that's what we did. Turned the ears inward and set the lid on top of them. You just needed about an inch or so to allow air to enter the tank.

 

You will eventually learn what causes it to hit hard and avoid those actions or if you can't, figure out when to lean forward out of the seat so it doesn't smack you in the back.

Make sure the seat isolator is unlocked as that can help lessen the impact. I always had it locked when I pulled dryvans and didn't really see the point of it...until I pulled tankers.

It's just part of the job. I would rather deal with surge than tarps.

 

Cool, yeah, them winter tarps are no joke. Won't it push you forward to the steering wheel though if you leave it unlock?

 

We had a 1-1/2" blowdown hose from our trailer to release the air through an air actuated switch when done unloading as we normally off loaded the product between 25-30 psi from the compressor on the tractor. We did have one customer that pumped off our load using a positive displacement pump. I never trusted the blowdown for the vacuum relief when using their pump. I always opened the dome and then let it rest on top of two wingnuts. Better to be safe than sorry.

 

It doesn't move that much but the sliding does help dampen the impact.

 

Just had to cut the seal and vent the tank on my current load so figured a picture would be good.



As you can see, even with me tightening the dome as much as possible there can still be some seepage as the liquid sloshes around. Most of that leaked out after I opened the dome though.

 

Ok, cool, what were you hauling btw, looks like chocolate.

 

That's the one, never been here before. Glad I didn't try to deliver early. I would have run out of drive time with nowhere to park.
