pto driven planer?

[cornish chough]

Has anyone tried driving a large planer from tractor p.t.o ?

Should not be a problem with the right gearbox.

H&S may have some thing to say about it if you get caught.

[se7enthdevil]

don't think they ever made any???

 

i would think that it would be fairly easy to rig up an old belt driven one though.

yes, its a h & s nightmare. you will need the correct pulleys to get good blade speed as most motors are 1450 rpm and tractors best is around 1035 rpm.

 

if you are doing it position the tractor well clear from the working area and bolt the planer down to stop vibrations, also takes up huge amount space in the workshop for a tractor or access to the pto point.

 

 

also why dose it need to be pto? is there no 3 phase or motor. its much easier to get a 3ph genset for the pto and use the machine as is

Back in the pre electric days, most planers and sawbenches weren't powered directly by flat belt/ lineshafting as the high speeds were tricky to obtain without tiny pulleys and tortured belts. They generally had an intermediate or countershaft to gear up the belt speed.

There's a possibility you could do the same with flat or V belts, but maybe best would be a 'speed up' PTO gearbox. PTO (Speed Up) Gearboxes for gear pumps - Speed up Gearbox 3:1 Ratio ML52B - Phoenix Hydraulics

 

Perhaps a PTO generator is the most practical way to go if you've no power on site. We've only got single phase but have a large rotary phase converter fitted which will happily run a massive extractor and several workshop machines at the same time. It's an excellent bit of kit, even if I don't fully understand the witchcraft that's happening within!

Dunno mate, but if you get this heath robinson like project going I would love to come and see it!!!

Thanks for the replies .yes a tricky project .no 3 phase on site so weighing up the cost of generator and fitting of 2 three phase motors against pto i do like the speed up gearbox idea though

-if you have single phase on site, consider using an inverter, google 'Drives Direct' - the cost of an inverter that will run off 240V 1∼ and output 415V 3∼ and run say a 10HP motor will probably be best value, + you have a load of additional functionality; like speed control, torque boost, soft start, also the running cost would probably be cheapest.

Funnily enough I have a 3-phase / single phase combi genny that gets used for welding about once every 3 years! Only 70 hours.

 

Genmac Combiplus 7900 RE - 8 kVA; probably not powerful enough?

hi John

no not powerful enough.

I have been thinking of generators though.

how's it going in deepest Devon?
