Ahh - all these questions........ Yes the crane is mounted on the tipper bed! The story goes like this - The Mog is basically a 1956 404, it had a weird one off body built we think for a madmax style film, it was horrible, and totally unusable!
So with the aid of a couple of 9" grinders, it was cut off behind the cab and plated off. Next came the hunt for a back, my bro just happened to have a nice alloy tipper off a Transit, fold down back and sides, with QD corner posts.
I was convinced I would need to cut a foot out of the width, but when I dropped it on with the Fergie..... it looked Ok! I made a subframe from 4" rsj pivots at the rear and a nice big 2 stage ram under (google - turnip7073 - how to move your garden) rear is 2m wide x 2.5m long.
The crane came later, I will check the make think it is Viking, it was electro hydraulic, I just hooked into my main system, Incidentally - all my stuff has to be made from recycled crap - isn't that right Tony? obviously to lift much with the crane it needs something to react against, so I bolted 2 x 1/2" thick 2ft square plates in the front corner and on the bottom one bolted a towball. hanging from the towball is a bit of 2" box with a ram inside - so you drop this leg down, extend the ram to steady the bed and lift away!
Also there is an air operated bolt which fires through the RHS chassis to stop that lifting up. I think it is rated 600Kg? but lifts way more! This way I can fell a tree, ring it up and use my timber grab to load the mog. I can do pics if you want? just say which bits!
If you do use a 404 pto, it is very slow and non livedrive, so drive your hydraulic pump from the engine direct or use a tractor 3:1 step up box (plenty around) which is what I need to do next! Phil.
