Model SP 561 LF - High Performance All Round Harvester Head

0

The SP 561 LF is a high-performance all-round harvester head. It is designed according to the LF principle for maximum productivity. The SP 561 LF is specifically designed for varied jobs and offers very good characteristics all the way from first thinning to medium final cut. The compact measurements in combination with a perfect delimbing down to 30mm make sure that the first thinning can be done fast and efficient with the highest quality. In final cutting, i.e. when handling large diameter trees, the smart SP patents LogHold and proportionally angled feed rollers turns the SP 561 LF into a harvester head with an impressive capacity/weight ratio and unrivalled productivity. The SP 561 LF is without a doubt both compact, broad and versatile. SP 561 LF reaches top performance in stands with a diameter of 15 to 35cm dbh but is thanks to the LF principle also capable of efficiently working with larger tree sizes.

The SP 561 LF has a very high level of standard equipment. However a number of different options are available for being able to optimize the harvester head for different needs, carriers and conditions. The below list contains the most common options. For more information please contact your nearest SP dealer.

Colour marking SUPERMARK

This equipment is used for making the forwarding easier when the qualities/lengths are very similar to each other and difficult to spot with pure eye sight. As the saw bar cuts through the stem SUPERMARK sprays a colour on the cutting area, marking it with a specific colour corresponding to the particular length/quality. By combining the two colours it is possible to mark up to 3 different qualities.

Multi tree equipment

The multi tree equipment makes it possible to fell and accumulate several trees before processing them. A very productive and time saving option for small size stems.

Hydraulic motors

In order to optimize the SP 561 LF for different carriers and conditions there are 3 different motor sizes to choose from. Do you need maximum speed, torque or a good mix? 514 - 560 - 625 cc

Feed rollers

Different feed rollers for different species and conditions.

Find end sensor

Makes operations in pre felled woods easier and more productive. With the find end sensor the harvester head reverses down to the root end of the stem, stops and sets the length to zero, all with the press of one button.

  1. SP´s patented proportional angulation of the feed rollers provides more carrying force the larger the trunk for lowest friction and maximum production.

  2. The floating top knife gives an excellent delimbing, lower friction as well as an easier processing of crocked stems. Casted in high strength steel for best durability.

  3. The three movable delimbing knives are casted in high strength steel for best durability. The upper and lower knives have a unique radius to each other providing an absolute perfect delimbing result all the way from 350 to 30mm.

  4. The frame consists of only the best possible materials. Parts of the frame that are in contact with the trunk is of a highly wear resistant material for longest possible life. The clean design of the frame without delicate components prevents wear and downtime.

  5. For optimum performance the SP 461 LF is standard equipped with separate knife control. This makes for example the processing of crocked trees as well as the reversing of large diameter trees an easy task.

  6. The length measuring unit is controlled by a strong and fast cylinder. In combination with the large movement of the measuring unit this ensures perfect measuring results also on bumpy and uneven stems.

  7. Delimbing knife number 5 is integrated in the saw box and helps with the delimbing of the lower part of the tree when positioning for the felling.

  8. The SP 461 LF is run by powerful piston motors, known for their high torque and quality. The motor arms are casted in high strength steel for best durability.

  9. The colour marking system SUPERMARK is one of many clever options. The colour tanks are strategically placed for best function and protection.

  10. The movable accumulating block for incoming hoses minimizes wear on both hoses as well as on the valve bank.

  11. All functions of the harvester heads are integrated in one compact valve bank for a minimum of hoses. The perfectly adjusted hydraulics works very efficient with a minimum of losses. In combination with the LF principle this makes the SP 461 LF a very fast and easy to work with harvester head with an unrivalled productivity.

  12. The main cover is hinged for fast and easy maintenance. The tight fit prevents dirt and snow packing.

  13. The diameter measuring is linked to both upper delimbing knives for best accuracy. The diameter encoders are well protected in sealed housings for minimum wear and longest life.

  14. The delimbing knives are equipped with long and perfectly designed cutting edges. This ensures that the limbs are smoothly cut of instead of broken off. This minimizes the friction during the feeding and gives a perfect delimbing result.

  15. The motor arms are equipped with robust protection plates for hydraulic fittings for less wear and down time.

  16. The robust and powerful saw unit SUPERCUT100 features integrated chain lubrication and an automatic hydraulic tensioning of the chain. The unique gear rack solution provides superior power through out the whole cutting cycle. Together with SP´s QuickCut this ensures an optimized cutting time and a minimized risk of cutting cracks.
