No tree shears were harmed during the video shooting.
This is the demolition of an old barn in Finland, with the Mastergrapple 1700 (tree shear Biojack MG320 without knife). The grapple structure made of Hardox is meant for forest harvesting, but we test it in other demanding applications to show its extreme durability. Its wide grapple opening of 170 cm makes a huge difference for handling any material. 💪🌲🇫🇮

Biojack MG320, tree shear with a large grapple.
The Mastergrapple 320 is a fixed knife tree shear, with a large grapple opening of 170 cm.
The knife is bolted and can be removed in 1 minute.
The grapple is fully made of high quality steel Hardox 500 and can be used for forestry work, or other tasks like demolition. Its structure is really tough and has been tested for root digging and pulling, as well as 3 t rocks uplifting.
In this video, the MG320 runs with 290 bar and has a quick movement valve to increase its speed.
