Specifically designed forbioenergy harvesting,cleanings or pre-commercial thinning, neglected forests, roadsides and power line corridors.The trunks are individuallycut and collected into a bundle in standing position.The bundle of trees is then stacked at a suitable place.Depending on tree species and dimension up to eight trees at the time can beaccumulated. Movement of the crane isreduced to a minimum, boosting the productivity.ABAB Energy Harvester purpose designed cutting knife ensures a high degree of utilization.The knife’s durability isconsiderable higher than of saw chains and brush cutters in similar conditions.ABAB Energy Harvester is engineered and built to last gives you the superior strength to continuecutting, cutting, cutting,cutting...We reserve the right to alter specifications or designs without prior notice.FELLING HEAD 251Technical DataWidth with open grapple 890 mmWidth with closed grapple 700 mmTotal height 1100 mmWeight with boom end 490 kgMax cutting diameter (pine) * 250 mmMax opening of grapple 590 mmRecommended pump capacity 120 l/minWorking pressure 21 MPa Max slew angle of rotator +/- 320°Tilt angle of the head 110°Voltage 24 VHydraulic knifeFELLING HEAD 350Technical DataWidth with open grapple 1150 mmWidth with closed grapple 980 mmTotal height 1293 mmWeight with boom end 980 kgMax cutting diameter (pine) * 350 mmMax opening of grapple 800 mmRecommended pump capacity 150 l/minWorking pressure 23 MPa Max slew angle of rotator +/- 320°Tilt angle of the head 110°Voltage 24 VHydraulic knife*) cutting diameter may vary depending on temperature and tree species.
