Hiab vehicle

[Davedb]

I’ve brought a hiab of a grab wagon big brute bit bigger than I was wanting really but price was right

I was thinking I’d mount it on tractor 3 point linkage but that will be too cruel the size it is so has anyone mounted a hiab on either a little trailer chassis or something else that would be handy around the yard

No good on a trailer chassis unless you stick a load of weight on the chassis low down as ballast

I’ve put a big one on the back of a tractor linkage (how heavy do you think a plough is) but if it’s off a grab lorry does it fold up properly

It’s the reach to the side that will be hard on a tractor I’d say? It doesn’t fold up completely but tucks In okay
Any pictures of the one you put on a tractor?

That’s only a wee thing you’d be fine with that on the back of a tractor it’s the legs that support it out to the side and the tractors weight holds it down

but what you need to do is make the linkage like a hedge cutter so it holds it tight and the weight will be pulled from the top link on the tractor to the lift arm ends on the crane

sorry no pictures, before mobiles had cameras

Did you get a grab with it

Problem with most tractor linkages is they are only held up. Most tractor linkages have very little if anything forcing them down and are therefore not designed to apply downward force. So when you start using a large hedge cutter or crane it becomes a bit unstable. Worst case is you put to much twist in the bar in the top of the gearbox that controls the link arms and snap it. Or the latch in the top of the linkage hooks give out and the crane detaches itself. This has happened repeatedly with big hedgecutters. So now they offer clips that bolt onto the axle so you lift the hedgecutter with the linkage and it locks into these clips. Transferring the force to the axle rather than the linkage. If you could source a set of these clips or indeed fabricate them it would be the best bet. The tractor will easily deal with the crane but the linkages arnt designed for the forces in the directions that a crane can give.

stick it on a dumper chassis .... or even the arse end of a dumper ... boom can sit in the skip then when travelling about and can fill the skip for ballast

I was originally thinking same as @Mogman says tie the linkage together or even a arm that presses under the link arm to stop it twisting the cross shaft, @Mogman you got any big lumps of plate to make mountains out of?

daft question to ask Moggy .... he's an entire scrapyard to pillage

Hedge cutters don’t have legs that transfer the weight to the ground and if you join the tractor top link to the lift arm ends it can’t go up or down

 

[Davedb]

Of course I have

Top man I was thinking make a saddle and use the bolts to fasten it to the crane?

Your better with thick wall rectangle section to bolt the crane to in my opinion

 

[Quattromike]

I'm sure I've seen some mounted above the cap of tractors when the were used extensively in forestry work. Would be a bit top heavy but handy

Local firm have this

 

[V8Druid]

I should've bought this (for not a lot, several years ago) ... be worth a hell of a lot more now .... friend sold up and went to Spain to live

You still get a twist with a crane that size though. And still pulling up on the lift arm hooks. You really need something extending under the axles that you can pull up and tension into the axle. Then do away with top link and make a frame that goes straight into the holes on the tractor that the top link usually goes in. Then no force through the delicate parts
