PTO genny

[BrokenBiker]

want to know more about PTO gennies for use on vehicles.

how do they work i.e. are they run off a belt etc

what sort of power output can you expect form them, are they avr etc

still haven't bought a van yet after mine dying, mechanic came back and said its muller'd, no point trying to repair so im still deciding whether its going to be a new engine or a new van. cheaper to get an engine and as the front of the van is off anyway it will probably be easier too.

anyway, interested in PTO for it but need more info. ideally would want to run 6kva mig from it and possibly a small 24ltr compressor just to run a few small tools and a spray gun

pto comes from gearbox not belt drive and also would need governing

 

[BrokenBiker]

cheers. only thought of belt drive as I can remember one of my dads mates putting an enxtra alternator on his ldv and using that to run something, cant remember what though

Depends mine is Pto driven from the prop shaft then belt drive to the generator and compressor. It uses a modified cruse control system to maintain the voltage/ compressor output. I don't know how many kva they are as it depends on the spec the original customer wanted.

it will be a governor as it will have to maintain 3000 / 1500 rpm depending on alternator under a changing load in order to keep the frequency right

 

[Forestryengineeringservic]

No they are based on a cruise control unit to maintain the engine revs rather then a speed. Well this is true for a winton one anyhow

 

[rtbcomp]

The cruise control is acting as the governor.

 

[BrokenBiker]

regardless of how it is governed it still has to be governed. this can be done many ways, your way just uses a cruise control unit to maintain the revs

One thing to think about - running it on white diesel won't be cheap!
Is it worth having a dedicated generator bolted inside the van instead?

well i have a genny now but it wont run a welder, ive done a bit of research now and I don't think it will be economical to use PTO either to be honest

Well, you need a bigger genny - about 9 or 19 kva for your MIG ought to do the trick.
