It looks to be but I'll ask anyway. Are the screw drives less fuss and muss than the hydros? It seems as it would also be more cost effective. would the motors power decide how much the dump could lift? Sorry for all the ?'s but Ive been looking at the Carson setup and the one sold at GT and they aint cheap. Thanks!

[Izzy]

the power of the dump is tied to the power of the motor - including the gear drive - but more importantly the angle of the push rod. Think of it as a triangle - the base frame - the push rod - the bed fo the dump. The more open the triangle the easier it is to drive - more flat or closed the triangle the worse it gets

Just as Izzy said the motor, Gear reduction unit, angle of the push rod, and pitch of the thread all make a difference in how well it works. There is a member on here named mustang that used one of the carson scissor lifts and he likes it but you have to notch out the frame to get it to fit. As for hyd cylinders I have one hyd lift dump truck and the way I built the thing hyd's were the best choise but I WILL NEVER DO IT AGAIN!!!

Thanks for the input Izzy these tips are what helped me get my dump trailer working.

Ive got a dump project goin but its kinda silly to have a dump that dosent dump. Thanks for the answers guys. I know I'll have more questions as your build progresses.

Great build thread, Travis!

Gotta ask - what are you using for driveshafts, and where do you buy them?

Can't find anything like those around here at local hobby shops...

Go to your local hobby shop and go to the Traxxas section they are the long slide shafts for the Stampead and rustler you can buy them in packages of 6. Here is a link.

And the yokes in this link go real well with them they are able to transfer more power to the axle than the axle can handle without breaking.

The truck looks great! You have my vote for build of the month! I was wondering what Rpm the dump motor is?

[fhhhstix]

Thanks the motor in the truck dump mechanism is a 300rpm motor but I have know idea what is in the pup I used a cordless screwdriver from Wall Mart.

Once again thank you for your help! I got everything together for my dump project (thanks to you). I found a good web site with gear box motors. http://www.robotmarketplace.com/prod...rs_geared.html

[fhhhstix]

I sold the pup dump trailer so I needed a new trailer for the truck to pull. I decided I would try to build a bumper pull equipment trailer and this is what I came up with. I still need to build the ramps and the mechanism to raise and lower them.









Thanks for looking.

Thanks John I have been wanting to build it for a while and just decided today would be a good day to start on it.

Yep these are more of my home made swing axles.

"START" on it... it looks like it needs some d-rings, mudflaps, and DOT tape..and down the road it goes..

[Snochaser]

Great job fiddlesticks! Your fit and finish just keeps getting better! Great idea, that's a heavy haul tag-a-long. I wish I could crack em out like you do.

Thanks snowball! I have a lot of ideas running through my head but not enough time or money for all of them. This was a kind of a simple one for something different.
