External installation with a case (Fig.1, Fig.2)
The external installation option is a good solution for objects where installation inside the premises is impossible (for example, in case of insufficient headroom or sideroom). The external installation is possible under the condition that the drive is protected with a case against adverse weather conditions.
The case covers the drive mechanism. This solution ensures safe installation of the door on the outside of the garage opening.
It consists of aluminium structure with steel side sheets fastened using steel brackets. The case is available in RAL 8019 or RAL 9010, and it can be coated in any RAL colour as an option.
The cover may also be used inside the room if the assembly conditions allow.
Important! In case of external installation the concave side of the profile forms the external side of the door and is visible from the outside. In addition, the power source, control panel and spiral cable (safety edge) are installed inside of the room.
The SI 17, SI 25, SI 40 drives feature emergency opening with a hand crank only. The SI 55, SI 75 drives feature emergency opening using a chain hoist or hand crank.
Internal shaft cover (Fig.3)
The partial shaft cover is recommended for the internal installation and serves as a drive shaft protection. It includes aluminium top and bottom cover in RAL 8019 or RAL 9010.
As an option, the cover can be coated in the door shutter colour. The covers are mounted on the galvanised steel brackets.
