IMPROVED GRASPING AND LESS DEBRIS
The angled knives help the timber roll into the grapple. With straight knives, there is a substantial risk of a log or branch landing perpendicular and interfering with the closing of the grapple. The A-grapple’s angled knives, on the other hand, feed everything that the arms grab into the grapple while forcing everything else out. This means that nothing ever gets stuck between the knives and the grapple easily dips into the log pile. Minimal surface contact with the ground also means that the A-grapple scoops up less soil and moss compared to a conventional grapple. The large spaces formed between the tips of the knives when closing also help keep the grapple free from debris.
UNBEATABLE IN STEEP TERRAIN
With an A-grapple, you can also pick up a log that is lying or standing on a steep slope. Simply rotate the arm tips inwards, lower the grapple so that the tips pass the midpoint of the stem, and close the grapple. The log will then simply roll into the grapple.
HIGHER PRODUCTIVITY WITH BOTH ROUNDWOOD AND BRUSHWOOD
In a study from Skogforsk, the Forestry Research Institute of Sweden, an A-grapple enabled roundwood to be loaded 4% faster and unloaded 7% faster than a conventional grapple. In addition to an A-grapple considerably increasing roundwood productivity, it makes for an excellent brushwood grapple. Unlike the airy bird’s nest-like bundles a regular brushwood grapple makes, the A-grapple’s angled arms compress the brushwood into tight bundles. This contributes to both heavier loads on the forwarder/timber truck and tidier brushwood piles.
