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.

Features

Excellent serviceability

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.

Equipped to meet the customer's needs

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.

Wide range of control and measuring systems

The KESLA harvester heads are compatible with the common control- and measuring systems at the market. Kesla offers different versions of proLOG-system, which has superb price-quality-relation.

Harvester equipment for excavators

Besides its extensive harvester head range suiting almost all excavator models, Kesla also provides comprehensive installation services and extensive accessory packages. Options selected by customers may include, for example, an installation kit for hydraulics, measuring and control system, Xtender boom and a full range of safety equipment.

Sturdy construction – long lifetime

Frames of KESLA heads (16, 18, 20, 25RH) are welded of steel plates to form a rigid one-piece construction. No bolted joints are used in the frames. The construction is light but extremely durable, thanks to the simple design and use of high-strength steel. Pivots are finally machined after welding, axles and bushings are perfectly aligned and exactly in the correct dimensions.

Excellent balance

Thanks to the well balanced construction and strong tilt pivoted close to the center of gravity, the KESLA heads are known of excellent balance both tilted up and down. Grabbing a tree is easy, and correct balance in processing position results in good delimbing force and quality.

Advantageous two-roller feed

With a KESLA head you will get the market’s best two-roller drive with unbeatable features: With only two feeding motors the construction of the head is simple, which results in excellent power-to-weight ratio and serviceability. Two motors mean also minimized flow resistance in hydraulics, meaning higher feeding speed and force with less fuel. However, thanks to the ingenious roller links with variable roller angle (the rollers carry the weight of large-diameter trees to maximize grip while smaller trees are clamped between the rollers to minimize friction) and hydraulic anti-slip system, we don’t compromise in grip and traction force. Less is more!

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.
