Thanks to its unique design and construction, the length measuring unit on SP heads offers exceptionally high reliability and measurement precision. The hydraulics are designed to handle extremely rapid movements and direction changes, ensuring that the measuring wheel always remains in contact with the stem. In combination with the high-resolution sensor, this ensures that correct measurements are made and transmitted within the system. The robust and durable bearings, the unique internal cable routing, and the non-contact mechanical sensor ensure reliability and dependability, even in the toughest conditions. Regardless of tree species, the measuring process can be optimised using different profiles and widths of the measuring wheels, while the large diameter of the measuring wheel ensures optimal contact with the stem attachment. This guarantees maximum reliability during penetration through various bark structures and minimal deviations, regardless of extreme high or low temperatures. Throughout the process, the length measuring unit is pressed against the stem by a powerful hydraulic cylinder with quick response times, ensuring exceptional length measurements, even on crooked and irregular stems. When the measuring wheel finally needs to be replaced due to wear, the easy-to-maintain design allows for quick and simple replacement.
The length measuring unit is powered by an extremely well-protected hydraulic cylinder and encapsulated flexible hoses, allowing the measuring wheel to be retracted into a protected position when the head is open.
The measuring wheel is equipped with highly robust, self-lubricating bearings for optimal service life and minimal maintenance requirements. The sturdy bearings are also sufficiently large to withstand the extremely high lateral forces generated, for example, when handling multiple trees or collecting crooked hardwood trees.
The length measuring arm is fixed to the head frame with a robust and durable connection to minimise maintenance and maximise durability. This also ensures extremely solid movement of the measuring arm without play, for maximum measurement precision.
Our larger heads, the SP661LF and SP761LF, which are often mounted on powerful carriers for working in tough environments with large diameter trees, feature a unique and fully protected cable routing to the length measuring sensor. Since the entire length of the cable is routed inside the frame and the measuring arm, it is always fully protected from external forces. This guarantees maximum reliability, even in the most demanding conditions.
The length measuring sensor is completely non-contact with no mechanical connection to the measuring wheel. As the sensor has no moving parts or exposed electronics, it ensures maximum reliability and durability.
Knife Profile
The delimbing knives are forged from high-strength steel and equipped with long cutting edges. This means that the limbs are cut rather than broken. This minimises friction during delimbing and allows the trunk to pass through easily.
Proportional Pressure
Proportional pressure ensures that the harvester head automatically operates at the correct pressure in relation to the tree diameter. This means that the friction between the trunk and the harvester head is minimised, and the harvester head operates at maximum efficiency. Individual settings for tree species further maximise productivity.
Log Hold
LogHold is an evolution of proportional pressure, allowing the delimbing knife pressure against the trunk to be reduced without the risk of the trunk falling. If the trunk is about to fall, LogHold adjusts the knife pressure to ensure the trunk stays in the correct position. The amount by which the diameter can increase before LogHold activates is set in the control system. No additional sensors are required.
Proportional Angles
This smart solution means that when the harvester head is fully open, i.e., at the maximum tree size, the feed rollers are at their maximum angle and provide the highest load force against the trunk. As the feed rollers carry the trunk, the pressure on the delimbing knives can be reduced, which means less friction, and the harvester head can feed the trunk quickly and easily.
The SP 561 LF is a high-performance all-round processor head. It is designed according to the LF principle for maximum productivity. The SP 561 LF is specifically designed for various tasks and offers excellent features from initial thinning to medium final felling. The compact dimensions, combined with perfect delimbing up to 30 mm, ensure that the first thinning can be carried out quickly and efficiently with the highest quality. The SP 561 LF is undoubtedly compact, wide, and versatile.
