Accumulating Energy Wood Head

Naarva E models have been equipped with accumulating grippers that significantly enhance the productivity of small wood harvesting. The accumulation of bunches in an upright position speeds up the work and reduces the number of crane movements required. Tree bunches that are placed by the harvesting track are easy to collect and load. The grapple is balanced and does not tilt forward even when the bunches being accumulated and handled are large. The modular structure of the E models allows flexible combination of the various frame, guillotine, and accumulating grapple options, to form a product that best suits each base machine and purpose.
