Felling Grapple Biojack 500S for Excavators

Saw grapple

2-in-1

Cut

Load

A sturdy and powerful grapple 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 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 is recommended for forest felling. 

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

The Biojack 500S 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. 

This grapple includes the saw unit SuperCut 100, with automatic saw chain tensioner and a dedicated chain oil tank.
