Safety is a big deal: GfA SI FI “Safedrive” offers the ultimate in vertical lift door protection.
When it comes to vertical lift industrial gates, fall protection is a top priority, and the GfA ELEKTROMATEN® SI FI series, also known as “Safedrive”, offers physical fail-safe protection by integrating a patented safety brake inside the gearbox. In this article, we look at how the SI FI series provides double protection for high-load, high-risk doors without sacrificing inverter performance.
For industrial doors that require fall protection, such as large vertical lifting doors, any failure of the control system can lead to serious safety accidents.GfA's “Safedrive” SI FI SeriesIt is a specialised drive unit designed for such high-security scenarios.
The biggest technical highlight of the SI FI series is the built-inPatented mechanical safety brakeThe brakes are integrated into the gearbox. Unlike conventional solutions that rely on external hoops or electric brakes, this brake is cleverly integrated inside the gearbox. In the event of an accident, such as a chain break or abnormal descent, this brake willPhysically, without delayAutomatically triggered to securely lock the door shaft and prevent the door from falling.
While guaranteeing absolute safety, the SI FI series does not forsake the pursuit of operational efficiency. Similarly to the high-end models of the FT series, the SI FI is also equipped with theBuilt-in frequency inverter (FI) It can be used in conjunction with door control systems such as the TS 970, TS 971 or TS 981 to realise theSoft start, soft stop and flexible adjustment of output speeds. Whether you need a large super-sized body for slow and smooth operation or a logistics corridor for fast response, you will find the right model.
The series offers a wide range of torque options based on a variety of gearboxes such as SG63, SG85, SG115, etc., with torque ranges covering from 100 Nm to an impressive500 NmOr even higher, enough to cope with the toughest industrial door conditions.
