Does anyone know anything about the sankey trailers that were driven from a pto on the land rover vehicle pulling them? Looking for info on them if anyone has any.....can't seem to find anything on google but maybe I'm asking the wrong questions. :o
There were driven gun trailers. They worked with 101s.

The idea of a driven trailer to assist travelling overland didn't work out as well as expected. I read somewhere during a military trials show, the driven trailer pushed over the towing LR when the LR turned too sharp. Not the thing to see when you are trying to sell the product. :o
John has found the write up and it explains the situation.
was there anything for the smaller narrow wheel based sankeys?
Getting pushed over would not be pleasant would it!??!?
For a long time I've thought that a electric assist on the trailer might be handy. Some thing that only provides power when you tell it to for those odd times when the trailer is acting like an anchor.
that's an interesting idea......what would it take Emad?
Put a rover rear axle under the trailer with a electric motor hooked up to the diff some how perhaps?
I Googled PTO driven Land Rover trailer and it came up with lots of information. Pictures of hitch used and how it is connected to trailer and among other things, a post on AULRO, (Australian LR Owners) about the trailer and one fellows idea of having hydraulic driven trailer. A pto or fan belt driven hydraulic pump to power a rover axle under the trailer. Joy stick control in the counsel and with camera coverage, you could drive the trailer like a video game. ;D
For you Series guys I have a PTO unit. ;)

How about a link to that thread Bruce...... ;)
Here's how the army solves such problems.

My suggested low budget approach....
Install a used, suitable rear axle from donor Land Rover. Get a used DC motor and speed control electrics from a forklift or gold cart. Mount motor to diff pinion. Mount lead acid batteries to trailer. Rig up speed control to vary with vehicle throttle and a switch to turn on for the short periods needed. Could add a disconnect switch on the surge brake to turn the power off if the trailer starts to push on the truck. AFAIK, the DC motor can just freewheel the rest of the time without adding much drag. You could probably add a manual disconnect on the motor or freewheeling hubs for when towing on the road.

ROFL
Maybe when I get that acreage and a nice shop. :'(
I've got some junk to help decorate the acreage when you get it.
Not so budget option.
I actually saw the 101 powered trailer and 101 prototype in the flesh during a visit to the Heritage Motor Museum in Gaydon, UK. It actually looked a fairly simple affair with a pass through hitch/driveshaft system sometimes used on older Heavy off road/Ag equipment. Good low speed but it obviously had issues with Squaddies and higher speeds.
I didn't spend too long looking at it however as I was much more interested in one of the original Darien Gap Range Rovers was parked next to it.
Fantastic place. If you ever get the chance I highly recommend a visit.
Is that the place that's open one weekend every second year???? That's on my list for next year I think ;-)

A link?? Just Google " PTO driven Land Rover trailer" It's only 5 words Bill, then you can look at all that is on the page, (or the 10 following pages), to your hearts content. I could possibly put up a link to AULRO post but you would probable have to sign in to see it.

Nope. That was the Dunsfold collection open weekend and it was last held in 2015.
This is the British National Motor Museum in Gaydon. It's open most days and has very early motor carriages to land speed record cars. I've been lucky enough to go twice and I've still not seen everything.

I'll just have to add it to my list then won't I ;D
Another option and probably less complicated than electric or hydraulic motors.
Here in Maine we call such trailers, Power Trailers.
We used to use them a lot here for getting pulpwood out of the woods. This was when papermills used to take pulp four feet long. We would cut the wood to that length in the woods, throw the wood on a trailer and then take the wood to a road where a truck would take it to the mill. It was a very efficient way to move wood because with all the wood on wheels, a small farm tractor could pull 1/2 to 3/4 of a cord of wood (full cord of 4x4x8). With a power trailer even more wood could be hauled; full cords or more!
That was because a power trailer was a home made trailer that had a trucks rear end welded to a frame. Then a transmission was placed at the tongue of the trailer. The tractors PTO would then hook up to the transmission and driveline. As you encountered mud, you would engage the PTO on the tractor. Power would then go through the transmission and turn the trailers wheels at the same speed as the tractor by finding the right gear to put the transmission in.
In a way the power trailer is superior to four wheel drive because with a power trailer, all the weight of the load is placed on the axle which is being driven, unlike a 4x4 tractor that is just having its front axle turned, but no weight applied. With a load on, some of the trailers weight would actually lift the front end of the tractor reducing 4x4 effectiveness. The downside is though, there is only one speed where the power trailer's transmission matches up with the tractors speed. In other words, the power trailer provides superior traction...at one speed only.
I have seen some power dump trailers as well as power woods trailers and I know they would be handy to have, but I do not know of any manufacturer that makes power trailers. Everyone I have seen was home-made. And while not a difficult task to do, with the popularity of 4x4 tractors these days, and papermills that no longer take four foot pulp wood, I have seen less and less power trailers around. Once and awhile you can see them advertised for sale for very reasonable costs. I would recommend anyone without a 4x4 tractor to get one though. They work extremely well in mud and snow.
A bit more information.

Here is some information about a 101 and powered trailer from AULRO.
Enjoy!

And here we go someone has made an electrical trailer drive set up.

Let me know how it works on a Sankey. ;D ;D
A quicky calc looks like a regular old 10 hp golf cart motor would work well and be a simple build. You can probably just use the whole combination axle/gearbox/motor. Maybe widen , if needed, or better hybrid it with Rover hubs. Be simple to get good adjustable control with the controller from the donor cart.
