Saw grapple 

⌀ 40 cm


The felling grapple Biojack 400S with a chainsaw is perfect in forest thinning and energy wood harvesting, as well as for wood loading and sorting. Its compact structure allows it to be used in urban felling, for cutting branches and cutting trees in complete safety. 

The cut is assured by the chainsaw. After the cut, the saw bar is into the grapple’s chassis, allowing the wood handling. 

The models including the SC100 saw unit also include the automatic chain saw tensioner. 

Three hydraulic lines are required (pressure, return, and free return straight to the oil tank). The chainsaw is activated with an electric command in cabin, which require an electric cable or wireless control for limitless rotation. 

The EG-kit is the Extra Grapple, the secondary upper grapple, which equips most of the models of these dimensions and offers even more grip power and safety for heavier woods. This option includes also the delimbing grabs for cutting the branches by sliding the grapple from the top to the bottom of the standing trunk, before cutting. This option is recommended for forest felling.
