6.4.1 Switching via clutch lever
The GKK gearbox is suitable for moving into and out of the material in drag conveyors or
similar systems of the materials handling technology. During the positioning process, the
clutch is switched via clutch lever. Switching is permissible at low speed difference (up to
10 m/min).
Note!
To achieve the highest possible service life of the components involved in the
switching process, a speed synchronisation is desirable.
With an integrated frequency inverter in the controller, it is also possible to match the
