Techinc Trailers and trucks

[5150 Lego]

So i tried this once before, but couldn't post pics up at the time. I manged to made a folder on brickshelf for one trailer, but the other two were left out. So here we are. I'll start with the one i previously posted, my two axal goose neck trailer.

This is a tipical trailer used to haul medium to heavy equipment Its made to tow behind fullsize pickup trucks, and meduim duty "mini semi" trucks. It hitches up to the truck by way of a ball mounted in the truck bed over the rear axle. This givesthe truck much better stability to haul larger loads. The landing gear is hand cranked so the truck can hitch/unhitch on uneven ground. Another pic with a tipical back hoe that you would see on trailers like this.

The next trailer is a boat trailer i use to haul 7244 speed boat. Though this is not a techinc boat, there was obviouosy nothing in the city line big enough to tow such a large behemoth! Needed a way to get it from the garage to the ocean and or lake, this was it!

The trailer has a winch system to pull the boat onto the trailer when its being picked at the boat launch as well as locking it donw to the trailer during transport between races. Its a 3 axle unit, with full suspention and hitches ot the truck via a standard bumper hitch. Shot with it hooked up to the truck,ready to go racie'in!

Here we have the cream of the crop! This is my heavy duty low bed semi trailer. This is whati use when i need to get the real heavy equipment to the job site. its over 2 feet long, and can haul 2 peices of equipment. It also has a rear hitch whitch allows a second trialer to be hitched up if needed. It has a fold down rampin the back, and storage up front for chains and warning cones and such. The landing gear is the same as the goose neck trailer. It hitchs to the truck via standard king pin on the trialer, and 5th wheel on the truck. This type of hitch is needed to haul such heavy loads.

I buitl this trailer spesifically for my 3 axle 8436 truck. I built it with the crane arm because i knew that i was going to build a trailer like this beforei even bought it. I added the third axle casue not only does it look better, but it really needed to support all the weight from the trailer when it was fully loads with construction equipment and such.

A shot with truck and trailer hitched up ready to go.

Thanks for looking. You can see the rest of the pics at my Brickshelf gallery.

Great work *y*

That truck just calls out for a trailer to make it complete.

I started work on a car transporter for it but never completed it.

Really, really good stuff there 5150 *wub*!

Very nice! I like the colour scheme especially - it matches the vehicles its designed to carry, and works well on its own.

Also, it's obviously sturdier than anything TLC Is making these days.

YAY technic beams!

BOO liftarms.

[Siegfried]

They are really good. Do you still have all these together? The boat trailer was a good idea. The only time I even had a technic truck and trailor was when I made the alt-model for the new Tow-Truck. However I bought that set for parts so it didn't last long.

I've had a closer look now that your brickshelf folder was moderated.

Even better than I had appreciated.

-independent suspension on the boat trailer

-very realistic looking hookup from yellow van to boat trailer

-clever ramp setup on the tailer for the backhoe

Although is is the smallest, I think I like the boat trailer the most - it does the most, with the least parts. It's practically perfect.

Minor thoughts:

-the fences you use on the big trailer somehow just don't fit with a truck trailer. I'm not sure what would work better. You have some unused holes in the technic beams underneath each of those fences... maybe you can attach something from the side using those holes?

-a winch or gear mechanism to bring up or down the ramp from the big trailer would be coold if it did not occupy much space (can it be from below?). Or could a pneumatic be used gratuitously for this?? Probably not because it woudl take up too much space.

-rounding off some of the corners of the trailers might make them look less "boxy". But I'm not sure about this. It could also make them look wierd, though. I wouldn't know unless I tried. I looked at some pictures of real trailers on the web and they basicall are platforms on wheels, without rounded corners.

-? mudflaps behind the rear wheels for realism?

Amazing. Congratulations on the authenticity of the trailers. Keep up the good work!

Thanks! The suspetion on the boat trailer was the hardest thing about it. Attually all 3 trailers have supsetion. The goose neck and semi use a "swing arm" that conescts both axles and then conects to the frame at the center point.

I'm working on a simular suspention set up for them like the boat trailer, but what i have now seems to work the best with the weight that they carry.

I've thought about doing that too. Just can't figure out what to do yet.

-a winch or gear mechanism to bring up or down the ramp from the big trailer would be coold if it did not occupy much space (can it be from below?). Or could a pneumatic be used gratuitously for this?? Probably not because it woudl take up too much space.

tried that as well. I can get the main platform to raise and lower with pnuematics, but then the second folding ramp still needs a way to unfold. Iv'e tried gears, but its to much wieght.

...But now that you meantion it, as the firsr ramp lowers down, the second one starts to unfold on itsown due to the weight, and angle. Imight not need it other than the pnuematics. Thanks gylman. I'm going to look into that a bit.

Yup. The front of the trailer is acttualy tappered a bit. I did this when the trailer was built when the truck was still a 2 axle. This allowed the trailer to be farther forward to the truck, and still allow it to piviot 90 degrees without hitting the crane on the back of the truck. It also aloowed room for the storage basket on the front.

Mud flaps are a good idea. I'll try out a few designs to see what looks best!

Very inspiring and clever MOCs indeed, 5150 Lego! *y*

Especially your boat trailer is a piece of beauty! :'-)

[Grand Moff Viceroy]

Very nice, yes it is.

[Paul B Technic]

Very well done with this, I have that truck and backhoe which I have been thinking about making a trailer for, this has given me some good idea.

Very nice, this is exactly what I want to build - but I don't think I've got enough parts - or expertise :P

But thanks for the pictures :)
