Mack Granite with Dump Trailer

[dabears]

OK more pics. Had a few people ask me about the suspension so here you go
PMD Trailer air ride drop arms
Russ's air ride for the arms and "airbag mount"
A lot of adjustments shimming etc. to get the right hight. Rear two axles have springs in them for support. the lift will have empty bags and prob a servo to lift.
Put the rear panel on and you can see it has mud flaps across the entire back and the rear door is slightly polished. Hand polish only on it unlike the sides that were buffed out.








Heres the lines JD just waiting for the new tanks to run them to the truck,


Thanks for looking I need to find a **SMALL** 7.2v lipo battery at least 5k mah.. anyone got a good place to get them from??

Boy oh boy it looks like the elf in Santas work shop has been busy LOL!

Looks great Mario. Thanks for the extra photos.

How small is small, for the battery pack? SMALL usually means you are stuck with a 1,600 mili-amp pack or somewhere near that. Can't really get the capacity as high as 5,000 mili-amps with something tiny. In my experience, most 5,000 mili-amp packs are going to be about the size of a 7.2 Sub-C sized 6 cell NiMh pack. Maybe a touch smaller.

Well it depends.... If I end up making front door windows on the mack and blacking them out ill have to put the battery there.... But where I was going to put the battery the pump now has to go.. Still trying to make it all fit somehow.

Aaron, I've seen guys stuff the UMS pumps in one fuel tank, and then use the other as the hydraulic oil tank. Might be something you could consider. Daycabs are always so short on space. I kind of wish there was a way to put a wet kit on my KW Needlenose, but I just don't think it's going to happen!

Very Nice...Always a fan of a good MACK build

I have to run duel fluid tanks due to the fluid volume needed to run the cylinder, original plans were to put the pump in a dummy tank..

Thanks guys!

Sweet combo!! You have been cranking out some really nice builds.Keep the pics coming and great job!!

[Espeefan]

Aaron, I've been looking around for small 5000 mili-amp packs, and I came across one in a different thread, here on the forum. Might be worth checking it out. Turnigy 4000 mili-amp, which is a little less then you might want, but it's one of the more compact battery packs I've seen. No idea of the quality though. I'm not really a LiPo guy.

Yes that would be perfect!!! Doesn't have to be LIPO but just figured they are smaller...


Ok so heres an update.. was Looking at the cylinder mount and didn't like that it was made out of the thinnest possible sheet metal possible (doghouse or whatever you call it) So I decided to venture into metal work Well I can say this I need better tools but for only using snips and a vise im pleased with it. so heres the thin POS that broke lifting 20lbs


So I took some thicker plate and made this





Then made a polished shiny cover




Didn't turn out too bad for a newbie in metal work lol




Ok so then there was the issue as to where the ----- to put the pump now... So since I was all into cutting metal with the snips today I cut some more, and some plastic and it resulted in this.





So hopefully tomorrow I can get everything soldered in and secured electrical wise. The Battery will just have to sit in the front seat for now until I figure a better idea for it. hmmmm Let me ask this.... If I Run a BEC off a 7.2 to run the pump and servos, can I run the esc for the drive off a separate battery thru the same receiver if I clip the red wire? I have a 11v battery I can run the drive off of but the pump is only 7.2 max.... suggestions?

missed this one oops thanks buddy!!

The new dog house looks pretty good for only using basic tools, Aaron. I didn't think the UMS pump was that small! Gee, maybe I could fit one in my truck someplace after all.

As for running two different battery packs - one for the pump, and one for the truck's drive motor, you should be able to do that without a problem, and use the same receiver for both. Assuming your ESC are identical, you don't have to worry about pulling the red wire of off one ESC, even though they will be running different battery packs and voltages. Their internal BEC output should be almost identical, regardless. If your ESCs are different, and have different internal BEC output ratings, then pick the ESC that has the more capable internal BEC, and pull the red wire off the ESC that you don't want to use. Or, buy an external BEC, and pull the terminal pin for the red wires off both ESCs. There are a couple different ways it can be done.

Yea I think I got the battery situation figured out.
Yes the pumps are small, quiet and strong!! I like them

LOL the house down the street is for sale... just sayin..


OK truck is fully functional minus the new tanks that are on their way. So heres all the wires done I still may add a second battery if I cant find a big enough MAH battery that fits. Heres some teaser pics no videos until the new tanks arrive....

Heres under the hood where the battery is mounted, the driveline ESC, receiver (which will be airtronics but I don't have the TX here....) steering servo and leads from pump esc


And here is underside esc for pump is in the dummy tank.


What ya think??

And the cab is free for a driver still didn't have to use it.



Thanks for looking

[Northern Farmer]

That's one beautiful dump trailer awesome job!

[jared31]

Wow just awesome.

I have that same rig in yellow, not a huge fan of all the plastic. But that trailer is sweet

[thebat]

here is an idea for ya for powering this whole unit off one battery solder a bec to your battery cable an use your 11.1 pack and set the bec to 7.2 volts and then solder that to your pumps power leads just an idea is all.
