Pump upgrade for dump trailer

[nisaacs]

I posted this on another forum so I though I would share it here. As all you owner operators of dump trailers are aware, the lift is super slow. For me, it is aggravatingly slow. For a home owner with once in awhile use, it is fine, in a commercial setting, not.

Calling all dump trailer owners/operators. Or just anyone with hydraulic experience.

If you have a dump trailer you know how slow they cycle. The bigger the trailer/hoist the slower they go. I think jhenderson put me on to a double pump system that is offered. I am really thinking about it or just adding a second pump. The double pump is expensive or about $800 more than a second pump. Since two pumps will have two tanks, my concern is, will the oil level stay equal or will one or the other overflow. I think I can adapt a fitting to the tanks and run a hose between them. There is an unused plug on the tanks that I think is 1" straight thread. Is there a 1" o-ring boss fitting? I think they are straight thread. What do you guys think?

Almost done with the conversion, still lack one o-ring boss #6 straight and both tee's. Sunday is not a good day to find parts, I did get all 4 hoses made, that was good.

I moved one battery out of the large section of the tool box and turned the existing one, for clearance to add the second pump. I wired one battery per pump and jumped the batteries together. I am going to run both controllers for independent use of each pump or both.

I will be all in for about $600 v/s $1200 for the double pump, plus what they don't furnish for the install.

Finished the two pump install. I like it! With two pumps in operation, it goes about twice as fast, as expected.

Why’d you go that option vs a gas motor?

That's with the double? That is still slower than my Big Tex 10LX albeit that's a higher rated trailer I'm sure. I bet it was agonizing if it was slower before.

Gas motor is still 2 GPM flow, $2200, manual control valve and you need room to mount it. My complaint is cycle time and needed/wanted more flow.

Here is a good side by side comparison of one pump v/s the double.

Let us know how big the difference is, at load capacity, when you get a chance. This is uncharted territory, from what I’ve seen.

Didn't seem like that big a difference going up, until the double started back down, still both are so slow!

I like the speed of my smaller capacity Big Tex 10LX (9999 GVWR), it is much faster and all I need.

That’s an eye opener. I can’t believe how long one has to wait for a single electric dump trailer pump. It almost makes the extra expense of owning a dump truck worth it, but not quite. Large CDL sized dump trailers at 20 grand+ are approaching the cost of a solid used dump truck, but the maintenance and fees of owning a dump truck are astronomical compared to a dump trailer.
I like the twin pumps. Definitely something I’d consider if buying a new one.
