what size of hydraulic oil tank

[Graham w]

Have you considered something like the running gear out of a decent size swing shovel , see I'm fairly sure that they have cornered the market in the most compact build size virus's the hyd power and agilitty

 

thats a fair point, problem was sourcing the engine, hydraulics and spools that were all in serviceable condition and the oil tank thats not part of the chassis. some of the akerman/volvo diggers have high psi around 5000 or 350 bar, but i would hate dismantling one (i would give it a name and put it in the garden:thumbup1:)

 

eventually we found an air cooled deutz engine with oil coolers built into the rear of the block and sauer pumps with low low hours. unfortunately i missed the rest of the machine that had lots of goodies like matching oil tanks, air filters and diesel tanks

 

three times the flow or even twice is a lot of oil

remember to tun the tank pressurised to stop cavitation ,for excavators from memory for that amount of oil flow the minimum size of tank would be around 250 litres and that is with an efficient cooling package
