Pon­sse Trac­tion As­sist Winch works in har­mony with other con­trol sys­tems

Fac­tory-fit­ted sys­tem gives peace of mind

Australian Forests and Timber - - Steep Slope -

FOR YEARS now, rub­ber tyre cut-tolength har­vesters and for­warders have proven to be very suit­able for steep ground log­ging in many coun­tries around the world. In these sit­u­a­tions, trac­tion as­sis­tance is be­com­ing more wide­spread as con­trac­tors and for­est own­ers search for lower costs and safer ways of log­ging steep slopes. Trac­tion as­sis­tance is the term used for us­ing a winch with a long ca­ble to as­sist trav­el­ling up and down the slopes while work­ing. A cor­rectly set trac­tion as­sis­tance winch cou­pled to the ma­chine’s trans­mis­sion con­trol sys­tem en­ables slipfree mov­ing of ma­chines pro­vid­ing re­duced ground dis­tur­bance, less stress to the drive trans­mis­sion and parts, lower fuel con­sump­tion and of course a safer and more com­fort­able work­ing plat­form for the op­er­a­tor.

The Pon­sse Trac­tion As­sis­tance Winch is in­stalled on har­vesters and for­warders as new equip­ment from the fac­tory. This pro­vides peace of mind know­ing the winch is fac­tory ap­proved and de­signed to work in har­mony with other con­trol sys­tems in the ma­chine and is cov­ered by the same war­ranty as the rest of the ma­chine. It can be in­stalled on the largest ma­chines that Pon­sse man­u­fac­ture, the 20t Ele­phant King For­warder and the Bear Har­vester as well as on smaller ma­chines.

Winch speed is syn­chro­nized to the ma­chine drive trans­mis­sion so that it au­to­mat­i­cally spools the ca­ble in or out ac­cord­ing to driv­ing con­trols. The op­er­a­tor teth­ers the ma­chine to an an­chor­ing point whether that be a stump, tree or heavy equip­ment by us­ing the hand­held re­mote con­trol to op­er­ate the winch unit. Af­ter pre­ten­sion­ing the ca­ble, he sets the de­sired ten­sion val­ues or pulling power for up­hill and down­hill and switches the winch to au­to­matic mode. While driv­ing, the ca­ble ten­sion is main­tained au­to­mat­i­cally. To make op­er­at­ing on steep slopes ef­fec­tive and safe, the winch is not the only op­tion re­quired. Ma­chines fit­ted with a winch also re­quire tracks, a tilt crane pedestal, a lev­el­ling seat with four­point seat belt, cam­era sys­tems and in­cli­nome­ter. All of these op­tions used to­gether will im­prove the ma­chine per­for­mance in steep ter­rain and add to the op­er­a­tor’s com­fort and safety.

Even a small vari­a­tion in op­er­a­tional slope and in ter­rain lay­out can be an ob­sta­cle for an or­di­nary ma­chine. Equip­ping ma­chines with the Pon­sse Trac­tion As­sist Winch avoids the ne­ces­sity and added costs of em­ploy­ing other steep slope log­ging meth­ods, such as sky­line yard­ing, hand fall­ing and ca­ble skid­ding along with their in­her­ent safety risks. A trac­tion as­sis­tance winch helps to mit­i­gate pro­duc­tiv­ity losses in for­ward­ing, too. No more lim­ited load sizes, long de­tours back to the hill­top or for­ward­ing only down­hill. Ad­di­tion­ally, for­ward­ing ca­pa­bil­ity does not have to dic­tate log stack lo­ca­tion and for­ward­ing di­rec­tion is free, up­hill or down­hill as re­quired.

The Pon­sse Trac­tion As­sis­tance Winch is be­ing used al­ready in nu­mer­ous coun­tries around the world, with the big­gest mar­kets be­ing Cen­tral Europe, Brazil and Western USA. It has proven to be a re­li­able way to harvest chal­leng­ing ter­rain ef­fec­tively, prof­itably and with min­i­mal ground dis­tur­bance.
