Thinning with an 8t excavator and head

[renewablejohn]

Deffo speak to FMS and/or Richard Court; 8 tonner will just run a Keto 100 but if you're wanting that new head, the Nisula picks up where the Arbro/Dinoma never qualified. The weight and oil flow requirements of the Nisula should be spot on; runs really sweet on this 13t.

 

 

PS your oil flow specs will be at pump, not at the end of the stick; good idea to get em measured.

 

But can you not see the problem in that video. The stand has been thinned in the past and is now being clear felled with the 8 tonne. The problem would be the previous thinning to get to that stand an 8 tonne excavator would be just to big and clumsy.

We've got a keto head on our 7.5t digger. It works well on thinnings and hard wood but the pump isn't enough really for big timber so it doesn't send enough power to the coils so every now and again the knifes will dig in but the rollers will let go a bit.

*13 tonner, not 8

Meant to be running @ 209 litres per minute

 

at what pressure?

Thanks said it for me! I'm doing first thinnings with a 16 tonne purpose built so how on earth can you say an 8t excavator base would be too big?!

at what pressure?

 

Working pressure is 260 bar

Pressure and Flow appear excellent (for a 7-8t) so if correct you could definately enjoy productive processing even with the larger Nisula 500; I bang on about them becuase they are light and no more expensive than Keto.

Compact Excavators Zerotail > 6 t | 75Z3 | Wacker Neuson

 

The Neuson is a good machine, plenty power, and fast with that flow.

 

Thanks for all the info/guidance

Nisula 500C - Delimbers, Price: £26,339, Year of manufacture: 2014 - Mascus UK

 

That is so reasonable; new H754 here costs £60k <100k for a 270 et al.

I looked at that head but was surprised it could only delimb 35cm although could fell 50cm.

Hmm that's odd The delimbing diameter is always less than the cut; mine is 620 cut and 560 delimb but it also says 400 tip to tip for the DK's so guess that's where the numbers come from. Thinning heads I find have short DK's and struggle to hold a large heavy stem when trying to put the first log through; end up running it along the stick on the ground.
