Telescopic dump trailer lift issue second test

[@bertkymalainen9425]

How did you adjust the pressure relief? I have 2 TP dumps in family and both do the same thing. I assumed that they just couldn't lift more as I know I was carrying a max rated load, evenly distributed.

[@ChrisTijerina]

I contacted the pump manufacturer and they shipped me a pressure relief valve with a higher rating for free

[@finders-keepers1518]

So in the end you still think the T lift is the way to go? I'm looking into the Diamond c trailers.

[@ChrisTijerina]

Yes, I think it’s the strongest and lifts the most weight

[@jossr71]

What Brand is this trailer??
i'm looking to buy a deck over dump with the telescopic setup.

[@ChrisTijerina]

It's a Texas Pride trailer texaspridetrailers.com/

[@jossr71]

@@ChrisTijerina thanks

[@sethclark3773]

Sounds like when it gets to the third stage it's low on fluid. While you take some off the back. In that amount of time fluid will drain back into the tank and then allow it to go on up. Just a thought.

[@ChrisTijerina]

That’s what I thought at first too, so I filled the tank completely full, and it did not solve the problem. The only thing that solved the problem was changing the pressure relief valve to a higher pressure.

[@danielschuld3398]

Pretty sure that cylinder requires 3.5 gallon reservoir and it looks like yours is 2.5

[@ChrisTijerina]

@@danielschuld3398 I've never had an issue with the cylinder having not enough available fluid. Only issue I had was the pressure relief valve was preventing the pump from lifting up the 3rd stage of the cylinder with a heavy load.

[@jamesrussell6870]

Each stage becomes progressively less, final stage being weakest. Stubborn load not dumping pushed final stage past max capacity? What brand trailer is this?

[@ChrisTijerina]

Texas Pride. I changed the pressure relief valve and it went up fine after that.

[@luisrojas495]

Hello Cris , i have a problem getting my dump trailer down empty. On the last stage got stuck, what do you think is the solution? Thanks

[@ChrisTijerina]

Is it a telescopic hydrualic just like mine with the cylinder at the front of the trailer or do you have a different type of lift like a scissor lift or dual ram set up?

[@luisrojas495]

Is the same just a gooseneck

[@ChrisTijerina]

@@luisrojas495 I've never had that issue but it sounds like the valve isn't opening fully to let the fluid back in or maybe the cylinder is tweaked or bent. I'm just guessing.

[@luisrojas495]

Isn't bent it , and if someone hung on the trailer, it will come down

[@masterzaga44]

So would you recommend this telescope trailer over scissor lift trailer?

[@ChrisTijerina]

Yes, absolutely

[@Rick75105]

Scissors is better for heavy loads ,no leaks like this telescope jacks.

[@ChrisTijerina]

@@Rick75105 Telescopic Dump Cylinders provide greater lifting power and can handle unevenly distributed loads significantly better than traditional scissor lift hoists, and I've never had any issues with leaking.

[@lyleschlabach6602]

how much weight was in the trailer?

[@ChrisTijerina]

Not sure, I didn't weigh it, but the hydraulics should be able to lift it regardless.

[@hooker4749]

have you checked fluid?...otherwise ask the dealer /professional

[@ChrisTijerina]

Yes of course, the fluid was the first thing that I checked and it was completely full. And then I checked with a dealer/professional and they did not have the correct solution, they replaced the telescopic hydraulic cylinder which did not fix the problem.

[@chrisao1987]

That’s an heavy load

[@ChrisTijerina]

Yeah and once I changed out the pressure relief valve with a higher one, it was able to lift and dump it no problem

[@truckstotractorsrepair]

Well maybe don’t overload it/put it all in the front lol

[@ChrisTijerina]

Texas pride's video here on TH-cam shows that this trailer with this hydraulic setup can dump a completely full load, it turned out to be the pressure relief valve on the pump that was causing the problem. This trailer needs to be able to dump a full load regardless of whether it's in the front back or middle

[@truckstotractorsrepair]

@@ChrisTijerina makes sense

[@IMAGOtrailers]

@@ChrisTijerina Go to a scale and get a weight certificate for the manufacturer and gauge the pump to see what your PSI peaking at. . The pressure relief valve should be at about 3,200 psi. (my guess). Dump trailers are rated at "water weight", which means even loaded front to back, top to bottom as if it was water.

[@IMAGOtrailers]

@@ChrisTijerina Don't just let them crank up the PSI, you'll have problems with the cylinder or belly of the trailer.

[@eliezeranguiano2622]

I have a TP 16k and it dumps fine. However, when I’m lowering the bed it can be anywhere from 10-15 min for the bed to come back down. Any ideas what it can be? Same setup.

[@ChrisTijerina]

I'm not a hydraulic expert but it sounds like the valve to let the fluid back into the tank is not opening fully

[@constructiontoolvideos2045]

Did you find out what it was? I’m going thru the same thing.

[@constructiontoolvideos2045]

Did you figure out the issue? Having the same issue!

[@ChrisTijerina]

​@@constructiontoolvideos2045 You're issue is with the cylinder going up or coming back down?

[@ChrisTijerina]

@@constructiontoolvideos2045 ​ You're issue is with the cylinder going up or coming back down?

[@austingriffith1118]

That's a massive amount of weight. Well over GVWR

[@ChrisTijerina]

What do you think the GVWR is on this trailer?

[@austingriffith1118]

@@ChrisTijerina it looks like a 7 x 14 trailer, so I would assume 14 K. However, even at 18 K it looks overloaded.

[@ChrisTijerina]

@@austingriffith1118 The GVWR on this trailer is 18K and it might have been overloaded but the telescopic lift was able to lift it once I changed the pressure the relief valve.

[@SvoBrianRobles]

Are these and U.S. built trailers the same ?

[@ChrisTijerina]

This is a U.S. built trailer, it's made in Texas.

[@SvoBrianRobles]

@@ChrisTijerina I meant Texas pride?

[@ChrisTijerina]

@@SvoBrianRobles yes, this is a Texas Pride trailer

[@yuriypono3666]

I see no issues other then you over loaded it to the front

[@ChrisTijerina]

No, the issue turned out to be that the pump had the wrong pressure relief valve installed. Once I changed to a higher pressure relief valve, it went up fine.

[@ChrisTijerina]

And if you put too much weight in the back of the trailer, it will cause it to fishtail when you're towing it.

[@Dirtpoorhomesteader]

Pono. You have no idea what you are talking about. The most difficult part of the lift was already done by the time the third stage of the cylinder wouldn’t engage. The first couple feet are the most difficult for any dump trailer and that lift was well past the midpoint.

[@yuriypono3666]

@@Dirtpoorhomesteader yeah what can someone who owns 3 trailers know? 🤣🤦‍♂️

[@Dirtpoorhomesteader]

@@yuriypono3666 I couldn’t care less if you had 100 trailers. Here is the definition of taking a argument from authority “An argument from authority is when someone uses an authority's words,( kind of like you owning 5 million dump trailers) not their reasoning, to justify an argument. The argument from authority is a logical fallacy because, at the end of the day, an authority's opinion is just an opinion. Evidence needs to be paired with opinion.” (Otherwise it’s just another armpit)

[@cd1168]

how long is the stroke on this cylinder? i have 1 from a pup trailer and wat to build

[@ChrisTijerina]

I'll have to measure it when I have a chance

[@highvalleycowboy1]

Its so slow it hurts my head

[@ChrisTijerina]

It may be slower than a scissor lift but it's a lot more powerful

[@redsite001]

Faster than shoveling it out.

[@ronwilliamson7697]

Battery

[@ChrisTijerina]

No the battery was fully charged, the problem ended up being the pressure relief valve on the pump. I replaced it with a valve that had a higher pressure relief setting and then it went all the way up with no problem

[@antoniocrisafulli4177]

Loaded too far forward

[@ChrisTijerina]

No that was not the issue, if you load a trailer too heavy in the rear, it will fishtail and be extremely dangerous to tow on the road. The issue was that the hydraulic pump had the wrong pressure relief valve installed in it. Once I installed the correct pressure relief valve, the trailer was able to fully lift all the way up even with the heavy load at the front of the trailer.
