View Full Version : Drop deck trailer photos

So, as promised, here are photos of the JGL (old Triple-L - 2,070 lbs empty, holds 4,500lbs, check your GVWR!) trailer that can be rented from Sunbelt Tool Rental. I recently bought a Bridgeport mill and needed to move it. I have moved stuff before but I thought that I would photo document this move a bit more. In doing so, I have had a few members ask about the trailer. So, here are a mess of photos. I will also be saving individual photos in the same photobucket album if you would like to go there and see an individual larger photo.

First up, the move. Here is a shot of the Mill being backed into the shop. The trailer is wide and will use a bit of the lane when driving down the road. If you cant used your mirrors to look behind you when driving (to monitor where the trailer is in your lane) you may want to get someone different to drive.

The vehicle door here is 8 (edit) foot tall. As such, this mill and many other machines are bought up to the door and then the deck is lowered a bit so that it can be backed in. Once in, the deck is dropped to the floor and the trailer is allowed to become level. I'll make another post of the move and how I got this off the trailer and into position.

Ok enough of that. The rest are details of the trailer with a bit of narration.

Suspension, interesting design.

Hydraulics - I like the idea of tucking them into the front of the rig under a door. The other side is a storage area. Both can be locked up with a padlock. Note the square hole in the bed. There is a lock that will snap into this hole and prevent the deck from falling.

More of the hydraulics. Also, the surge trailer brakes.

Deck mechanism - Large cam follower type bearings are in the channel of the deck support.

Misc - Here are some shots of the deck in general. Binding rings in 3 places down each side of the deck. Gussets and weld points are also shown. And cool little cutouts in the middle of the ramp showing the marker lights. These look sweet at night.

Misc continued - Close up of the binding rings and the gussets under the ramp. If you think that you want to build one of these, put more gussets under the ramp. Dont ask how I know.

Here is a video of the lock that holds the deck up.

Thats it.

When I checked into this after seeing one a local landscaping company uses, all the components were widely available here with the exception of the wheel spindle carriers. None of the suspension shops here had a clue about the dual spring system. :(

Is it possible it is a proprietary design?

The link below leads to a manufacturer that seems to imply that they are the only game in town for these units. They come complete with the rest of the trailer..http://www.ecomallbiz.com/premco/customhtml/

Thats a nice trailer, thx for the effort to post........smile

RR are you sure thats a 10' door? Unless you or your buddy is 8' tall........LOL I brought my Excello with riser through my 10' on a carhauler that doesn't lower..........

Hum... My fingers must be running faster than my brain. It's 10' wide by 8' high. Nice catch. I'll go correct.


Camdigger, I wonder if you could call the manufacturer and ask for replacements? They might well be proprietary. I have seen only one other design similar using forged arms and airbags (and one with springs). I would bet that the Triple L spindles are cheaper as an assembly than the forged ones. That may be why we see more of these trailers than any others.

We use a camrol bearing at work that looks like it would fill the bill as far as the bearings go? They look almost identical to these:

Here's a better picture: http://img148.imageshack.us/img148/384/mgcrescamrol.jpg (http://img148.imageshack.us/my.php?image=mgcrescamrol.jpg)

You can see that they are held with a hex socket while the nut (1-7/8") is tightened. The shaft above the threads is where it slides through a bushing. The application we use has a hole in each end for a grease fitting. When I get back to work in a few days, I'll grab one and take a few pics of how they work if anybody's interested?

Those rollers are widely available. I've used them on special machines too.

The hard to find item is the dual leaf spring wheel spindle carrier. I suppose I could use the ones with the spindle monted to a plate, but the ones I've seen are low speed spindles (off an old Ford hay baler), not highway spindles.

A carrier base shouldn't bee too hard to weld up from plate and angle and the spring components are readily available from the local spring shop...

Ah, ok. I see. I guess I mis-read it? :o

Several years ago when I was moving my lathe and mill, Sunbelt had one of those but wouldn't rent it out. They said that it was part of another piece of equipment. I sure would have made my move easier. :(

Sorry to nitpick........blush

I would say my fingers would be running faster but really either possibilty is unlikely..........LOL

Ya know, that spindle plate doesn't look like it would be that difficult to fabricate. Plate, flat bar, a spindle.....

A guy could make it any size he wanted, to fit the springs and other stuff scrounged outta the junk yard.

Now most of this is just thinking out loud. Or typing out loud....

So, I'm flipping around through the Northern Tool Catalog and there are spindles for trailers in it. The heaviest spindle is rated at 1750 lbs. So that a pair is 3500 lbs total. The trailer I was pulling was 2070 lbs empty. That would leave 1430 lbs for the load at which point you would be maxed out. I'm sure that my mill was heavier than that.

I would think that a fellow would need a spindle that could hold 6000lbs similar to this Spindle link (http://www.championtrailers.com/spindles_n_parts.html) This seems as though it is more specialized. Probably so, we aint hauling the same stuff as the normal weekend warrior.

This does not take into account the plate design and leaf springs needed. Which as I think about the trailer, the leaf springs in this design control camber. If they are too long or too light, as the trailer is loaded the tires will move into positive camber. That might be a more specialized spring, dont know for sure.

The rest would be statics, materials, FEA, and I wonder if the DOT gets involved at some weight. Then I'm betting you'd need a PE stamp and insurance. My uncle builds his own trailers, weighs them at the grain mill, gets a stamped slip of paper that he takes to the license/title place and gets a tag. There has to be a weight limit, and I wonder if his insurance agent knows. Hummmmm.

Now I'm curious. I might need to give ol uncle a call.

Well, Champion Trailer is the first place I look when I need something for a trailer. :D

But you're not stuck with standard spindles if you don't want to be. Sure, it would be a PITA if you went off special but it's a possibility.

Camber would be set by the angle between the spindle and that fabricated plate thingie. The springs would just go up and down. And the top and bottom springs would be the same.

True, the springs (top and bottom) would be the same, my thought is that as the trailer is loaded, force is delivered to the spindle. The spindle and bracket is not long so the leverage is delivered to the springs as a side load (as well as the normal up and down). I have not seen leaf springs in a side load application similar to this before.

So I had wondered how they hold up. I did notice that the springs seemed a bit more stout and wondered if they were special.

Here is a link for JLG they sell trailers to haul around sizzor lifts. http://www.jlg.com/en-US/ProductLine.html?BaseProductLineNodeId=b42a2f8d-df93-4461-9cff-e7aa25242d55&ProductLineNodeId=09883463-2fbf-4d18-ae96-84a6fbb8fdb9&GroupProductLineNodeId=bc2fd324-a965-4f8c-8a30-630b47ee24a7&ProductRootMenuId=d39badf6-70c2-4fa3-a03c-268cb1f085d7

They are well buit and have many sizes if you needed parts I am sure they would sell them to you.

Hmmm, that an interesting thought about how the springs might not track vertically. I don't think the springs would twist if they were stiff enough (but how would you define that!) but that side loading isn't what normal spring hangers and shackles are designed for. Well, the springs do see some side load in the older cars without link arms or sway bars but I don't know how that side load would compare to the side load in the trailer.

Hmmmmm. Very interesting! Need to think about that stuff.

Yep... That's exactly what I used to haul my last two BP's around. And.. unloaded then with a pallete jack!
