About us

Biojack - Finnish expertise in thinning

We design and manufacture multifunctional tree shears and harvesting heads, mostly for energy wood, first thinning and tree care, for all kind of machines, from ATV to heavy diggers. 

We simply asked foresters

The original idea of Biojack dates from back in 2006. The owner of Nummek had a solid background in forest equipment and wanted to develop the company’s activities. We simply asked foresters what they need to harvest energy wood. Two main properties came up always: cutting and loading capabilities. So we designed a first tree shear with mobile blade and tilt, the Biojack 150, and launched it in 2008 with the motto CUT & LOAD. This very first Biojack 150 prototype is still in use to this day!

Striving to make work easier

We perfected our grapples, added different options like the delimbers, the stem collectors, the wireless control, developed the range, according to what our customers wanted. In 2010, we launched the Biojack series for excavators.

Our product range is extensive, since we wish to serve our customers in the widest possible way – from professional contracting to performing minor jobs. The purpose of the energy grapples we produce is to make users’ work easier. We wish to ensure that our grapples are always multifunctional, easy to use and reliable. We cooperate with Biojack users on an ongoing basis to make our products even better. Only the best is good enough for us.

We have gone international!

We expanded in Scandinavia, Europe and overseas. We ship tree shears and saw grapples to 30 different countries for a global amount of nearly 2000 felling grapples to this day. We offer our dealers training and support for selling and marketing our products.

Add efficiency to your future

Nowadays efficiency is becoming ever more important, and challenges faced by any business are growing. While having to be more efficient, the end result of the work must also be better. One can respond to such growing expectations in ways other than by making working days longer or by working harder. Biojack’s multifunctional grapples make work easier and swifter, while improving safety and quality of work, which means that grapple users can reach their goals faster and better. Biojack will help you to achieve better results.

We are a small, spirited, and fair-minded family owned company from Southwest Finland

Our grapples are manufactured by Nummek Oy operating in the same premises. Biojack Oy and Nummek Oy cooperate closely in developing and production of grapples. Our cooperation has been yielding user-friendly and reliable products for harvesting energy wood since 2008, when our first device – Biojack 150 – was launched. We continue developing our products constantly.
