Difference in Sand Box & Prop Box????

What's the difference????

I see the coveted "Sandbox" I read about, but now I've seen the set up with 2 boxes called "Prop Box."

Are these the same things???

One dude at a TS was talking like his Prop Boxes were the end all to be all, and Sandbox was doomed.

 

Prop x is the liberty version of sandbox. Have you seen the arrows up boxes? That’s the future no belts of bull crap and it’s almost dustless can be hauled on flatbeds. Btw this is coming from my experience as a lead service supervisor for a huge Frac company

 

and sandbox won’t ever be doomed because of how much Halliburton had to fork over to them all of big red is hugely invested in sandbox

 

I still don't even know what sandbox is. But I'm curious why the one has two boxes, and the other has one.

 

Frac sand was normally carried in dry bulk pneumatic trailers(like my avatar). When you delivered at the frac well you would blow the sand off into large boxes(they look like oversize box trailers). There would be lots of noise and dust. With the sand boxes you arrive at the well and a big forklift lifts the box off your frame or drop deck trailer. He gives you and empty box and you leave. Faster and dust free. A pneumatic trailer holds around #48,000, the sand boxes are a little less, maybe #38,000 to #42,000. You can't haul 2 loaded boxes(unless you have an overweight permit). But you can take 2 empties when you leave the site.

 

Sandbox is made as a system, special box and frame trailer. In the nose end of the trailer is a ladder which has L brackets that fit into loops on the trsiker to keep it in place.

When a driver arrives at the loading place, they stop and pull the ladder out and attach it to the side of the box, then climb up and open a hatch on top. After loading they climb up, close hatch, and stow ladder in the trailer nose.

That last step apparently gets forgotten so trailers sometimes have a hardware store ladder bungied onto the nose, because if it's left on the box and not noticed it gets taken along when the boxes are switched.

Halliburton likes them, especially when it's time to review their contract with Brady, who still do pneumatic.

But that costs them, at the site they need to have the special unloading system to get the sand out of the box.

So it's a specialsed proprietary system, can't use the trailer for anything else, need unloading setup, etc.

The kind of system that a company that purposely derates its trucks almost to the point of uselessness would get into, just to spite a long-time supplier.

 

Sand box? I thought Dave in AZ was talking about his cat box...

 

Perhaps the Prop boxes are smaller. The ones that are called Prop X always see two, they can't all be empty.

That's what I see them using alot in WHY-OH-MING too.

 

The prop x are about 15k each when loaded they have to make different variations because of patent reasons... look at the sandboxes you’ll see two very distinct patterns on the sides... that is because Halliburton made an identical “sandbox”. The original sandbox sued them and won so Halliburton had to pay sandbox to utilize Halliburton’s own system. They also had to put the sandbox name on the Halliburton boxes. It was and still is a huge deal cause Halliburton is the largest oilfield service co and at the time sandbox was so small

 

Sand Box, Arrows Up, PropX all carry the same matter that is in MOST, not all, of the heads of sand haulers in ND and MT.
