Hydraulics
Metric | |||
Min. pump capacity: | 250 l/min | ||
Rec. working pressure: | 26-30 MPa |
Feeding
Proportional clamping pressure of the feed rollers in relation to trunk diameter, individual settings for different species for optimum performance. | |||
Roller motors: | 780, 934, 1043, 1248 cc | ||
Max. opening: | 700 mm | ||
Feed speed: | 3.9 – 6.3 m/s * | ||
Feeding force: | 46 kN | ||
Proportional pressure: | Yes |
* Depending on feed motor choice.
Cutting
The SuperCut 100 is a very powerful saw unit with integrated chain lubrication and hydraulic tensioning of the chain. Together with SP’s QuickCut, this optimises cutting time and minimises the risk of cutting cracks. | |||
Cutting diameter: | 750 mm | ||
Chain speed: | 40 m/s | ||
Saw motor: | 32 cc | ||
Saw unit: | SuperCut 100 | ||
QuickCut: | Yes |
Tow sawing (option)
Cutting diameter: | 380 mm | ||
Chain speed: | 40 m/s | ||
Saw motor: | 20 cc | ||
Saw unit: | JPS |
Delimbing
Proportional delimbing knife pressure in relation to trunk diameter for minimum friction and maximum production. Individual setting of upper/lower knives and for different tree species for optimum performance. | |||
Movable knives: | 3 | ||
Fixed knives: | 2 | ||
Delimbing diameter tip to tip: | 510 mm | ||
Delimbing diameter incl. lower knife: | 550 mm | ||
Min. delimbing diameter: | 40 mm | ||
Proportional pressure: | Yes | ||
LogHold: | Yes |
Weight and dimensions
Despite its enormous capacity, the SP 761 LF is suitable for more than just large-diameter felling thanks to its compact design. | |||
Width closed: | 1400 mm | ||
Width open: | 1920 mm | ||
Height: | 1850 mm | ||
Weight: | 1750 kg | ||
Height with top saw (option): | 2030 mm | ||
Weight with top saw (option): | 1880 kg |
Recommendations
Carriers | |
The SP 761 LF can be fitted to both conventional forest machines and excavators. In order to ensure good function, please consult your nearest SP dealer or SP staff. | |
Felling | |
Proportional clamping pressure of the feed rollers in relation to trunk diameter, individual settings for different species for optimum performance. | |
Optimum tree size (DBH) for highest productivity*: | 20 – 56 cm |
* Diameter at breast height, measured 1.3 m up the trunk. |
