Carson Goldhofer Trailer
So I was looking for a trailer to put behind my Grand Hauler. I had a unpainted Carson Goldhofer collecting rust here at work. I said its low and painted flat black it could go well.
So I figured it would be a good start, it will not have motorized legs but for now it will be a good match. The one thing I did not care for was the rear ramps being manual, I have seen some motorized with homemade gear but no real detail on how it was done besides a very few images. So I figured I will give it a shot. I will be using one of our Tamiya planetary gearboxes and some creativity. I hope you enjoy and it helps others |
Re: Carson Goldhofer Trailer
So you can see I have the planetary gearbox built

Re: Carson Goldhofer Trailer
Mocking up placement, you can also see that there are a few wafers removed. You can adjust the gear ratio but removing or adding wafers.

Re: Carson Goldhofer Trailer
Created a mounting plate for the gearbox.

Re: Carson Goldhofer Trailer
more info needed about the 7.2 to 12 volt step up
i got the carson dropdeck from tam usa love it.. |
Re: Carson Goldhofer Trailer
Well I picked it up from amazon, I imagine there are more than just this one. But Amazon gives me free 2day shipping and great returns with prime.
http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1 Its more than just 7.2 to 12v, it is fully adjustable with the small blue onboard pot. The readout shows your voltage both input and output by pressing the micro onboard micro button. |
Re: Carson Goldhofer Trailer
Be warned I have gone through two of those step-ups so far. There are reviews on amazon that they can burn up easily. I am looking into other options as well. Luckily with prime membership I just returned them for refunds.

Re: Carson Goldhofer Trailer
I saw Goldhofer and I was expecting to see a modular trailer,, Anyone ever built one?

Re: Carson Goldhofer Trailer
Great work. I share your annoyance about manual ramps and was wondering how to get over it.
Now I know . . . . . I would say about your step up module that all electronics are twitchy about over-voltages and equally under-voltages although the former is most likely to fry your unit when you first fire it up. Maybe as it's only for the ramps without any real load consider a continuous servo with micro limit switches rather than your excellent gearbox idea. Might be cheaper too as it's all stock parts for just a few bucks Just a thought and trying to help . . . . . BTW how do I get a job like yours ? ? ? ? ? ? :D :D :D |

The stock ones got worn out so I had to hunt down some new lines that did not stretch. Once I did that I was working out the lengths and adjustments to get the ramp-ends to fold again. I was making some good progress. As far as the gearbox and electronics, everything was working well for me. I will update this thread when I resume the project. As far as getting a job like mine, 1st you would need to be in the USA. :D |

Re: Carson Goldhofer Trailer
Ok, found some time and needed to get away in the man cave. Here are some updates.
Replaced the voltage step-up unit and this one is working nicely. https://c1.staticflickr.com/9/8803/1...f91f4f20_c.jpg Added a clear coat to wood and a rotating beacon light to ramp bottom. https://c4.staticflickr.com/8/7755/1...109dbeb0_c.jpg |

Re: Carson Goldhofer Trailer
Your trailer is looking really good so far. I've been following this thread with a lot of interest as I just picked up a used Goldhofer and am starting to rebuild it. Mine was in pretty good shape except for the ramps. One of the plastic pieces that bolt to the end of the ramp was broken and all the cylinders were removed. I machined new hinges from aluminum but am struggling with the cylinders. The manual I found lists one as A the other as B. How do you know the difference? I don't want to hijack your thread but any help would really be appreciated as I'm having a heck of a time getting the ramp ends working.

It's all based on the spring location inside shock unit. A= is the collapsed unit that you have to pull against spring B= is a sprung unit that you have to push against spring to shorten. Hope that helps. |
Re: Carson Goldhofer Trailer
Some updated photos. Working on some smaller details at the moment.
