Thanks all.!
Sooo many questions..?? makes me ..
well.. I will try to explain some of them..
Started this project in november 2008, but have been thinking about it for
three years before starting to build. In that time I was able to collect some
important hydralic parts that has the right price on it.
The total price for the project so far including the conveyor witch will be
included in test 3 is 750$. Sofar I'm on the + side..
Pumpstation Parts:
2 p hydralic piston pumps from Sunfab(1017SR) 275bar (27,5mpa)
when connected the produce 160l/min and max pressure 275bar.
2 p 3/4" hoses on the pressure side and t 2 p 3/4" on the Tank side
that feeds the processor.
1 p 200l oil tank
The pumpstation is mounted (3 part) on one of mine tractors MF 178 (80 hp), when
pressing the system to what it can give the tractor dies..witch is only
producing 160l/min and 230bar! so more power needed!!
Firewwod processor parts:
1 p piston Rexroth 350bar, piston diameter is 12cm. and it can give with
maximum pressure 40tons. Today with the tractor I'm using 20tons. (Witch is enough!) ;-)
(The knife with 8 wings is blown away when I using hardox 600.
)
1 p two side valve 200l/min 350bar
1 p Parker hydralic sawengine F11-19c (19cc) 350l/min / 400bar (10.000rpm) on saft.
Double-power compares to Binderberger SP 450 and Porsch.
only using the Supercut 1000 from hultdins Parker F11-10 (10cc).
The complete sawunit was taken from an Harvester unit Hultdins K55E, witch had some broken parts on it.
bought it for 400$. With that unit comes automatic chainsaw oil feed and feedout bar speed and pressure.
All this is done automatic.. more oil and pressure .. more speeeeeeeeeeed..
Today the unit give 45Hp and 30 meter / secound on the chain speed.
The return movement of the sawbar and timber arm is made by airpressure tank on 10bar.
1 p orbirtrol motor for the feed conveyor. (And yes i slippering when the wood is weath or has snow on it, the
plan is to run this on good days = nice weather..)
It produces 8-9 cm3 (don't know the messaurement for us.?) wood per hour, so I'm using 35-40 cm3 wood per year.
so I will have all done in a day.. this includes putting up the machine with timber feeder and demount it..
I think a got it all..
the sawunit will get a protective huve over it.. planned for test 4.
