Hydraulic power pack

Just purchased power pack to power homemade splitter rather than use tractor. I have to say one of the best purchases i've made. Two stage pump 18 hp engine, had it running most of the day on £7 of petrol, tractor free to do tractor jobs :) Long hydraulic pipes to reduce fumes, and now looking at hydraulic chainsaw to run of it. Much more compact and more space in the shed.

A bit of a co-incidence.... this afternoons job is to make a list of hydraulic fittings needed for converting a large electric driven hyd power pack recovered from a massive paper guillotine. A few fittings and we will hopefully have a silent running fume free splitter. :001_smile:

Be carefully, some power packs are 400bar or 750bar rather than ~200bar!

 

so if your splitter was on a tractor and as tractors have their own PRV which works independently of the PRV on the spool valve of the splitter, there is scope for the PRV on the spool valve of the splitter to have never been set properly but this hasn’t shown its self as the tractors own PRV has been kicking in stopping over-pressure.

 

remove the tractor from the system and mistakenly put a 400bar or 750bar hydraulic power pack to the splitter without checking the splitter PRV setting or adjusting the power packs PRV down, then in conjunction with the PRV on the spool valve of the splitter being incorrectly set you may get massive over-pressure. ;)
