Pon­sse IT ap­pli­ca­tions in wood har­vest­ing

Australian Forests and Timber - - Control Systems -

To­day, har­vesters must be ef­fec­tive, re­li­able, and ca­pa­ble of mea­sur­ing wood ac­cu­rately, and they must also be easy to use and en­vi­ron­men­tally friendly. The ful­fil­ment of these re­quire­ments can be greatly en­hanced with the help of in­for­ma­tion technology.

For example, each Pon­sse for­est ma­chine has the Op­tiCon­trol in­for­ma­tion sys­tem with a pow­er­ful main com­puter, plus sep­a­rate in­te­grated com­put­ers for the con­trol of all of the cen­tral func­tions, such as the drive trans­mis­sion, the crane, har­vester head, levers, the diesel engine, and the lev­el­ling of the cabin. All these mod­ule com­put­ers are in­te­grated in a com­mon net­work, which can be called an “in­tel­li­gent over­all sys­tem.” Com­put­eraided op­er­a­tion makes the move­ments of the ma­chine quick, ac­cu­rate, and easy to con­trol. Fur­ther­more, nu­mer­ous other au­to­mated func­tions, such as au­to­matic buck­ing, greatly in­crease the ef­fi­ciency and ease of use of the ma­chine.

Pon­sse har­vesters are equipped with an au­to­matic buck­ing sys­tem that makes it easy to ob­tain the best pos­si­ble cut­ting com­bi­na­tion from the trunks, which en­sures that sawmills are de­liv­ered the right spec­i­fi­ca­tion of tim­ber to fill out­stand­ing or­ders. This in­creases the added value of the wood for the plant of sawmill. This method ben­e­fits the land owner, the pro­duc­tion plant, and the ma­chine owner. A wire­less data trans­fer sys­tem en­ables the ma­chine to send pro­duc­tion in­for­ma­tion to the owner of the ma­chine and the for­est com­pany and re­ceive new log­ging and cut­ting in­struc­tions for fu­ture log­ging sites.

Right place, right time

In ad­di­tion to con­trol­ling for­est ma­chin­ery, in­for­ma­tion technology also has a cen­tral role in the man­age­ment and lo­gis­tics of wood pro­cure­ment. The lo­gis­tics of wood pro­cure­ment in­volve the con­trol of round­wood from the for­est to the pro­duc­tion plant. The round­wood must be de­liv­ered to the right place at the right time with min­i­mum costs. When tim­ber pro­cure­ment lo­gis­tics is ef­fi­cient, raw ma­te­rial is care­fully used, the stor­age pe­riod is short, empty run­ning of tim­ber trucks is min­imised, har­vest­ing is cost-ef­fec­tive, for­est dam­age is min­i­mal, and co­op­er­a­tion be­tween var­i­ous seam­less.

For each stand, a rep­re­sen­ta­tive of a for­est com­pany pro­duces in Pon­sse Op­tiEdi­tor a so­called buck­ing file or APT file, which in­cludes the tree species, as­sort­ments, and the length and di­am­e­ter tar­get dis­tri­bu­tions within each as­sort­ment to be logged from the stand. Prior to log­ging, this buck­ing file can be sim­u­lated in Pon­sse Op­tiSimu with a dig­i­tal group of trunks that rep­re­sents the stand to be logged. This en­sures that pos­si­bil­i­ties of­fered by the stand, and the de­sired log­ging re­sults are in balance. op­er­a­tors is

Ac­cu­racy is key

The mea­sur­ing de­vice Op­ti4G in Pon­sse har­vesters mea­sures the di­am­e­ter of the trunk within an ac­cu­racy of one mil­lime­tre and the length of the trunk within an ac­cu­racy of one cen­time­tre; it also makes an es­ti­mate of the stem curve for the cur­rent stem based on the stem bank col­lected dur­ing pre­vi­ous op­er­a­tions. The di­am­e­ter and length dis­tri­bu­tions in each as­sort­ment as re­quired by pro­duc­tion plants are set in a price ma­trix used by the mea­sure­ment de­vice in de­ter­min­ing the op­ti­mal cut­ting points for the cur­rent stem. The first es­ti­mate is run at the butt, and the cut­ting sug­ges­tion
