The SAT640 fixed felling head is a large capacity fixed felling head with 2 sets of jaws that can be independently operated or at the same time as each other. The wrist that the SAT640 is mounted off has 360 degree continuous rotation. This wrist can be connected directly to any Excavator bucket C linkage.

The SAT640 saw unit is supported by a large 30 cm (12”) diameter slew bearing making it a very robust unit especially when felling. The saw utilizes a heavy duty SATCO® auto chain tensioning system with a 50” bar and 3/4” chain.
SATCO® also use a unique locking system for the saw sprocket to prevent broken drive shaft keys and damaged saw motor shafts. The saw bar has a unique 270 degree rotation making a front cut easy to perform without having to reposition the base machine from felling position.

The wrist is mounted to a large diameter slew ring specially designed for this application. There is a purpose built rotate motor used to drive the slew with an override holding relief built into to motor. There isalso a float option which can be easily engaged when shoveling or loading.

Weighing in at 3700 KG (8175 LBS) and requiring 200 LPM (52.8 gpm) (US) at 280 Bar (4000 psi) this felling head does not require much from the matched 29-45 tonne base machine it is connected to.

The SAT640 advantage over a dangle type felling head is where there is an application for controlled felling. The SAT640 can also be used to shovel, load a truck and has an advantage on steep slope to assist in support of base machine. The SAT640 is also useful for sweeping the skid site of forming a track on a steep hill-side.

The SAT640 is constructed using high grade materials and manufactured using the best robotic welding wire for a far superior weld.
