L’abatteuse à impulsion KESLA 25SH-II fournit son meilleur rendement lors du traitement des arbres noueux, exigeant une grande puissance de coupe lorsque la force des têtes à alimentation à rouleaux ne suffit pas. L’alimentation à impulsion n’endommage pas la surface de l’arbre et elle est adaptée au traitement du bois précieux. 25SH-II s’adapte aussi bien aux coupes d’arbres droits qu’au traitement des piles. Le diamètre optimal de l’arbre est de 40 cm.
La combinaison de mâchoires et de lames de coupe supplémentaires uniques fournit plus de force pour le traitement de grands arbres et améliore le rendement de coupe. Le système à impulsion partiale proStroke facilite le traitement des arbres noueux. KESLA 25SH-II s’adapte aux machines de base de 10 à 15 tonnes.
Special attention has been paid for ease and convenience of daily maintenance. Thanks to the spacious structure of the Kesla heads, for example lubrication and change of hoses are easy to do.
The Kesla heads are always equipped according to the needs of customer. With the wide range of optional equipment and accessories there is always a Kesla head that perfectly fits to you.
Les mâchoires de moissonneuses KESLA sont compatibles avec la plupart des instruments de mesure disponibles sur le marché. Kesla propose des systèmes proLOG de différents niveaux et dont le rapport qualité-prix est excellent.
Kesla propose, en plus d’une vaste gamme de moissonneuses s’adaptant à presque tous les modèles d’excavatrice, un service d’installation complet et des packs d’équipements variés. Le client peut choisir pour son engin, par exemple, un pack hydraulique, un instrument de mesure, un bras Xtender et des équipements de sécurité complets.

Stroke harvester suits also onto smaller basemachines, like diggers, which hydraulic oil flow would not be high enough for roller heads. Even with relatively low oil flow, stroke feed creats feed efficient enough to cut and delimber relatively big tree trunks. The product itself is produced of the same high quality materials than the roller heads. The measuring device is a part of standard delivery and equivalent to that of roller heads. The SH-heads are very widely used throughout the world.
Depending on the harvester head model, the new saw unit utilises a 34cc or 40cc Sunfab motor and 22-tooth drive wheel that enable a sufficient chain speed to be reached at approximately 5,500 rpm. The low-rpm, high-capacity motor is much more durable in use than traditional solutions and operates at much better efficiency. In practice, this manifests itself as better sawing power and lower fuel consumption.
In addition to the fuel savings, the technical solutions of the R5500 saw unit result in lower operating and maintenance costs: The saw unit utilises wide Iggesund JW-series saw bars, whose life span is many times that of traditional bars. The robust and wide saw bar bends and vibrates less, which, together with an efficient tensioner, ensures that the chain stays on in all sawing situations. The new double-sided and balanced drive wheel is designed to last for the entire service life of the harvester head.
The JPS R5500 is a compact package that does not require external saw cylinders or position sensors. The saw bar motion is driven by a turning mechanism integrated into the unit, which also includes sensors that detect the position of the saw.
According to the studies, it also produces substantially less cutting-induced crack than its traditional counterparts.
