SEE-NHK
Roller shutter drive with crank-operated emergency operation
Product information
The SEE-NHK drive for roller shutters combines the simplest end position setting with maximum operational safety in an emergency. In addition to the well-thought-out features of the SEE drive (maximum curtain protection and firm closure of the shutter), it can be operated manually with an emergency hand crank – for example, in the event of a power failure. After being manually cranked upwards, the SEE-NHK drive automatically re-learns the end positions.
SEE-NHK drives must be installed with rigid shaft connectors or anti-lift devices and require a fixed upper stop.
Parallel operation of multiple SEE-NHK drives is possible.
Available in BR 2 (from SW 50). Adapters must be ordered separately. Articulated bearing mount: 7 mm hexagon or 6 mm square.
