18RH-II

With the new frame, delimbing knife, shaft and bearing solutions of the KESLA 18RH II, efforts have been made for even better durability and a lesser need for service even in the most demanding operating conditions. The new, more spacious system achieves higher feed force and speed with significantly reduced fuel consumption. The feed is now supplemented with a hydraulic traction control. Along with the changes made in the structures and hydraulics, the serviceability of the head has reached an entirely new level.

The KESLA 18RH II is also available with a single movable rear blade. The rear blade improves the delimbing of the trunk and keeps the big trees in the jaws better during the feed.

The new KESLA 18RH-II is suitable for installation on basic machines weighing 7 to 13 tons, and large agricultural tractors/excavators of 7-10 tons.

Equipo de excavación

Además de una amplia gama de modelos de cosechadoras, compatibles para el trabajo de casi todos los modelos de excavadoras, Kesla ofrece servicios integrales de instalación de equipamiento adicional. En función de la tecnología de su equipo, el cliente tiene la posibilidad de seleccionar, por ejemplo, el sistema hidráulico, el instrumento de medición, la unidad Xtender y el equipo completo de protección.

Diseño robusto, garantía de larga vida útil

El armazón de los cabezales cosechadores KESLA (16, 18, 20, 25RH) se compone de placas soldadas de acero, que forman un diseño integral y robusto. El armazón de los cabezales cosechadores no tiene articulaciones atornilladas. El diseño es ligero pero extraordinariamente robusto, gracias a la sencillez del modelo y al acero de alta calidad que se ha empleado en su fabricación. Las articulaciones soldadas se manipulan de forma mecánica, los ejes y bujes están perfectamente alineados y tienen las dimensiones adecuadas.

El equilibrio produce eficiencia

Un diseño perfectamente equilibrado y fiable que posee una óptima inclinación del cabezal con respecto al centro de gravedad, garantiza el equilibrio del brazo KESLA, tanto para la tala, como la poda de ramas. La alimentación y la tracción de la madera se realizan rápidamente. Gracias a un buen equilibrio de la posición de la madera, el brazo empuja los troncos con facilidad, garantizando una alimentación sencilla y un corte del ramaje que se distingue por su gran calidad.

Boquilla extendida de 2 rodillos

Los cabezales cosechadores KESLA tienen características únicas, gracias a su avanzada boquilla de 2 rodillos: diseño de brazo más robusto que el brazo con cilindros de 3 y 4 rodillos, que se considera la mejor opción en el mercado en términos de potencia y peso y de mayor comodidad de cara al mantenimiento. Por otro lado, es menos propenso a que sus componentes sufran algún daño. Contar con dos motores, en lugar de cuatro supone que la lubricación del sistema se produce de forma independiente del usuario, lo que implica una gran ventaja desde el punto de vista del ahorro de la potencia y el combustible. Gracias a su perfecta geometría en el giro de los cilindros y a un sistema de tracción hidráulico, basado en la asistencia de dos cilindros alimentadores, se alcanza la máxima eficiencia y fuerza motriz.

Productfamily FAQ

What is the difference with stroke and roller harvester?

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.

Why should I choose JPS R5500-saw?

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.
