Biojack is small, spirited, and fair-minded family-owned company from Southwest Finland. Their grapples are manufactured by Nummek Oy operating in the same premises. Biojack Oy and Nummek Oy cooperate closely in developing and production of grapples. The cooperation has been yielding user-friendly and reliable products for harvesting energy wood since 2008, when their first device – Biojack 150 – was launched.  We continue developing our products, and therefore the original Biojack 150 grapple has now been replaced by the new generation energy wood grapple – Biojack 160.
