The Forstreich SK50 spiral cone – handy, small & powerful
Thanks to the self-retracting spiral of the SK50 spiral cone with KWF-Profi certification, the saw cut does not need to be widened. This makes it ideal for safely felling weaker wood and small trunk diameters. Weighing just 1.7 kg and with a maximum stroke height of 55 mm, it exerts an impressive 5 tonnes of pressure on the tree.
Properties and application
Two hardened hexagonal sockets with wrench sizes 16 and 22 with holes are available for connection to the impact wrench. This allows the SK50 spiral cone to be conveniently combined with our other felling wedges and used, for example, for repositioning.
The symmetrical shape of the spiral reliably prevents the SK50 from working itself out of the wood. A large, lubricatable roller bearing ensures efficient power transmission and a long service life.
