QuickLock – an innovative technique for quick and easy chipper knife change

Metso's innovative knife fastening system QuickLock differs fundamentally from traditional systems. A totally new approach has resulted in an ingenious knife fastening system, which gives higher chip quality and easier operation as well as considerable time saving at knife change.

Quicker and easier knife change
In QuickLock knives are fastened using a revolutionary new technique, which makes knife change both simpler and quicker. This innovation eliminates the timeconsuming work of cleaning, loosening, fastening and checking the torque of many knife bolts. There are no slots on the disc face, providing an even surface against the logs, which results in a smaller amount of fines and pin chips.

Simplified knife change
To change the knife just loosen one bolt, which releases the entire knife clamp. After the knife is changed simply fasten the same bolt to close the knife clamp. The bolt can be loosened and fastened either manually with a wrench or automatically using an EasyTurn rotation device and a remote-controlled EasyTool, which is specially designed for the purpose.
