2020 Kesla Roller Feed Harvester Heads 25RH-II
The KESLA 25RH-II models are truly versatile harvester heads for thinning and final felling where the trees’ average diameters are less than 40 cm. The head’s maximum opening is 58 cm. The excellent balance, combined with the geometry of the rollers and knives, facilitates and speeds up the picking of trees either standing or laying on the ground, either vertically or from bundles lying on the ground. The head is also well suited to the processing on landing.
Features may include:
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.
- Frames of all KESLA heads 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.
- 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.
- Kesla is the only producer that offers JPS 5500 saw factory installed. The JPS 5500 saw offers several benefits for the user: durable motor, better efficienfy, less fuel savings, lower operating and maintenance costs and substantially less cutting-induced crack than its traditional counterparts.
- 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!
- 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.
- 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.
- The Kesla heads are always equipped according to the needs of customer.
