Big­ger machines de­but at Elmia Wood 2017

New Zealand Logger - - Forest Talk -

IT ONLY COMES AROUND ONCE EV­ERY FOUR YEARS and of­ten show­cases up­com­ing trends, so an­tic­i­pa­tion for the Elmia Wood forestry show in Swe­den is al­ways high, and the 2017 edi­tion held last month didn’t dis­ap­point.

At­tract­ing more than 50,000 vis­i­tors who come to see the lat­est in­ter­na­tional in­no­va­tions dis­played by 550 ex­hibitors from some 30 coun­tries, Elmia Wood is Europe’s premier forestry event, with this year’s promis­ing to be big­ger and brighter than ever.

New Zealand con­trac­tors have tended to think of Euro­pean forestry equip­ment as be­ing mostly too small and too light for our re­quire­ments, and there is a fair amount of truth in that be­lief, but there has been a trend to­wards big­ger machines in re­cent years.

Amongst the usual lightweight equip­ment on dis­play last month, some gen­uinely in­ter­est­ing machines from a New Zealand per­spec­tive were on show in the forestry site south of Jönköping, in cen­tral Swe­den.

Among them were a Ger­man-made log skid­der, which put paid to the no­tion that Euro­peans are only in­ter­ested in car­ry­ing cut-to-length wood. A com­pany called HSM builds a range of for­warders that can also con­vert into very use­ful clam-bunk skid­ders, which sell well in Ger­many. On show at Elmia Wood was the lat­est 8-wheeler HSM 208F model, which is rated at around 19 tonnes and of­fers a 184kW (250hp) 6-cylin­der Iveco diesel en­gine. Sim­i­lar in con­cept to the Tim­ber Pro 840

for­warder/clam­bunk, it can be used for drag­ging tree­length stems or to for­ward cut logs. In­ter­est­ingly, it can be equipped with a front-mounted winch to pro­vide ex­tra trac­tion on steep slopes.

As if to em­pha­sise the big­ger-is-bet­ter mes­sage, Tiger­cat also de­buted it new top-of-the-range wheeled har­vester that has been de­signed for heavy-duty op­er­a­tions in “ex­treme ter­rain”.

The Tiger­cat 8-wheel drive 1185 har­vester is a ro­bust 34-tonne ma­chine de­signed for high pro­duc­tion clear fell ap­pli­ca­tions on steep slopes.

Pow­ered by a Tiger­cat FPT en­gine, rated at 230 KW (308hp) it fea­tures a cabin that ro­tates with the boom and has ded­i­cated pumps to power the drive, har­vest­ing head, boom, fan and cool­ing cir­cuit func­tions. There are two stick boom op­tions — fixed or tele­scopic.

Some­times, size doesn’t cut it in the for­est and you just need to keep the wood mov­ing, so maybe the Swiss Tracked For­warder, mak­ing its in­ter­na­tional de­but at Elmia Wood, might work. Sure, it’s on the small side, but its tracked de­sign is made to haul wood over any sur­face, as our photo shows.

For wood yards, the Lieb­herr L580 LogHan­dler XPOWER is a highly mo­bile ma­chine that can stack logs higher than a tra­di­tional wheel loader. This 36-ton­ner has a newly de­vel­oped driv­e­line that com­bines hy­dro­static drive and con­ven­tional for­ward drive to re­duce fuel con­sump­tion by up to 30%. The special lift arm of­fers a max­i­mum reach of al­most four me­tres.

Lieberr also showed the smaller L518 equipped with front and rear steer­ing axles for tighter turn­ing cir­cles for the first time.

In other news from Elmia Wood, Husq­varna pre­miered its newly de­vel­oped X-CUT saw chain, which dif­fers from com­pa­ra­ble prod­ucts by cut­ting faster with lower vi­bra­tions. It stays sharp longer than com­pet­ing chains on the mar­ket and is supplied pre-stretched, so it can be used im­me­di­ately and does not need fil­ing so of­ten.

And Fin­nish ma­chin­ery man­u­fac­turer, Nisula, un­veiled an ex­ca­va­tor track frame that is move­able length­ways to pro­vide 4WD-like ar­tic­u­la­tion for im­proved travel over rough ter­rain. When the ma­chine is sta­tion­ary the track frames can be locked to pro­vide the re­quired sta­bil­ity for work­ing.

The 8-wheel-drive HSM 208F can be used as a clam-bunk log skid­der, as well as a for­warder.

Above clock­wise:

1. The all-new Tiger­cat 1185 wheel har­vester weighs in at 34 tonnes – it’s get­ting closer to a tracked har­vester in clear-felling. 2. If the go­ing re­ally gets tough, the Swiss have an an­swer – the Swiss Tracked For­warder.

3. Husq­varna de­buted its new X-CUT saw chain at Elmia Wood 2017.

4. The high-stack­ing Lieb­herr L580 has a hy­dro­static/con­ven­tional drive combo for much re­duced fuel con­sump­tion.
