Springs or bogies?

[7610 super q]

Solid beam between the axles on a pivot.

Rocking beam, with no suspension ?

Yes, that's what I understand it means.

We have an old 8t Marshall on 6 stud axles with springs. It is not fun tipping muck out of it on a slightly unlevel site. Our 10t on bogeys is solid as a rock when tipping.

I would take bogeys unless going for commercial spec springs.

My QM11 silage trailer is very stable on springs... But this silage time we borrowed a neighbours 8t Marshall on springs and I’ve never seen a trailer lean like it! Looked like the dragchopper was gonna blow it over a few times

Our is an old Wheatley design. Been over a couple of times and now a bit twisted.

Depends on the bogie... see above

I know but I wouldn't expect any manufacturers to make an offset bogie that puts more weight on the front wheels than the back, unless maneuverability is the priority. I've heard people say that springs push the wheels into the ground but I can't see that they would.

We had one of those at a time, we made it a foot taller. It often looked like it was going to go over but it only landed on its side once, the 15/55-17 wheels we put on seemed to steady it. A lovely towing trailer, you never felt or heard it behind you. Was it that made me think about getting the new trailer on springs.

So for your benefit @7610 super q, the question is sprung axles or rocking beam axles?

Springs for me. My only experience of rocking beams is my old JF muckspreader converted into a trailer. An unfair comparison, but me no likey.

You put LESS weight on the front wheel, have a look at an old wootton trailer, the pivot is about 1" forward of middle, easy to not notice, when in soft ground the front wheel runs a little higher than the back counteracting the natural thing for it to dig in and run on the front wheel only. It reduces power requirement by about 25% on soft ground, but you will get faster wear on the rear set.

It was some other makers patent so not all had it, I had to request my last Wootton to have it.

Our maize contractor's Redrock was like that.

Maybe didn't explain it well. I know you'd need less weight on the front wheels for them to climb out. The previous comparison between springs and bogies on identical trailers with the same tyres suggests that springs are better in the wet, the opposite of what most people claim. Springs should put equal weight on each wheel, as should equal bogies so there shouldn't be any difference between them, but there was. Unequal bogies would have an advantage, except wouldn't the pivot be to the rear of the middle rather than forward of the middle?

Redrock have always promoted their off centre bogie axles. The amount of steel they use they need all the help they can get to stay afloat

Yes your right it is to the rear.

A spring would be better than an equal bogie as the front wheel is limited movement downwards whereas the bogie front wheel can fully dig in until the bogie beam hits the chassis at the rear,........ at which point you are probably stuck!

9 times out of 10, if a trailer is on it's side in a field it'll be on spring axles. Bogies can also take more punishment along old, rough roads.
As for the ' getting stuck ' debate, if it's that wet it doesn't matter if its sprung or bogie, you shouldn't be there in the first place.

 

[v8willy]

You need offset bogies so the front carry less weight and climb out of the soil, wootton used to do them all like that.

Kane also supposed to, but I never looked.

Stupid question but don’t most sprung twin axle trailers have a mini rocking beam between the front and rear springs? I know my marstons do but can’t picture other brands at the moment. The only rocking beam trailers I’ve used seem to suffer from wear badly and end up with splayedtyres.

Any sprung tandems I've used have a small rocker between the springs, I assume they all do.

OK, I give up, what's a bogey ? Not something you find in your nose , surely ?

Rocking beam

 

[Boohoo]

Well the answer for me this time was bogies or for the benefit of @7610 super q rocking beams.

Herron recommends them for this size of trailer, they're more stable, have better ground clearance and should be more manoeuvrable since the axles are closer. The bogies are an off centre design so should climb out of any soft spots .

What is that for? Never seen a trailer like that.Dropside, front rack and rear extension s?
