so what happens in high rpm low boost situations?

boost comp trims fuel in low boost rather than low rpm.

 

Boost comps trim fuel at the top end as well and you trim fuel and top end with the ROM settings on E pumps

 

Boost comps increase fuel slowly as boost and rpm rises

only on overboost and depending on pin. put a decent ramp pin in and they often don't have the ramp for overboost.

 

Most start to trim before over boost and the governor sorts the rest, E.G no fuel no boost no smoke. pin has nothing to do with it.

@Charles the last pic does not look like NZ, but I like it.

Can you fold the stands?

No, those are all from the UK, worked for a beekeeper for 5 years running about about 1600 hives. They are all ling (heather) sites. Yes the stands fold up, you can see them on top of the trailer in the first photo.

0.05 shows your trailer has very very stiff suspension. those wheels are virtually parallel to the trailer. is it binding somewhere ?

No that's how it is.

The suspension needs to be rock solid to support the crane loads without outriggers.

you WILL end up smashing the tow vehicle and trailer coupling.

the springs will handle the crane but you need to have equalizer action in the suspension. even more critical on a 3 axle due to the bigger distance between front and rear axles.

If it brakes Ill just fix it.

The springs do have rockers and the entire running gear set up is on a separate boggy that is u bolted to the trailer (no welds)

The thing is bullet proof as is the truck.

Ill do expect to continue wearing out tow balls and couplings though.

Now I grease them and use a swivel coupling

its not much much fun when it breaks out in the field at the worse possible time and the repair may be a major.

 

i don't get this kiwi attitude of using badly designed trailers. its so easy to make something fit for the purpose.

Kiwis tend to do things,

Many others just talk.

No offence of course Tristan but at times you can be like a dog with a bone.

You just wont let it go

 

I can be the same though, thats why I dont mean any offence

trailers are a bit of a sore point.

we get loads of them broken down on the highway, often missing wheels. (you know its summer when you see broken down trailers on the side of the road)

poorly spec'd, abused, uncared for and over engineered to try and make up for it.

does AA do call outs when its covered in bees?

AA never used to insure you if you went off the tarseal !

 

just remember that it may not be the trailer that fails. seen vehicles where trailer issues have caused tow vehicle chassis failure.

 

the annoying thing is the trailer industry. they don't use good gear cause no ones asks for it. customers want big heavy stuff that doesn't break when they put double the load on, not gear that actually works correctly.

frustrating when your trying to build something that will handle the rough stuff and all they got is old rejected designs other countries won't use.
