Felling Grapple Biojack 650S for Excavators

Saw grapple




The biggest saw grapple from Biojack, for forest harvesting, urban felling and wood handling.

In municipal applications the grapple can be used, for instance, for removing trees around power lines and buildings. The trunk is cut with a chainsaw. During the loading cycle the saw remains in the frame and is activated by pressing a power button; this means that the grapple can be used flexibly for cutting and loading.

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, the upper secondary grapple, is an option for forest felling, granting a decisive supplementary strength for holding, moving trees vertically and felling heavy loads. 

The hydraulic components are well protected into the rear casing, while being easily reachable. 

The Biojack 650S can be mounted on a telehandler or on an excavator, with different coupling solutions. The TD rotator is available with its swivel joint for limitless rotation.
