GIGAsedo Operators: TÜV-Certified and Safe Without a Spring Fracture Safety Device
The GIGAsedo operators from SOMMER set new standards in door operator technology. Comprehensive tests by an independent testing institute have confirmed that our operators can be used without an external spring fracture safety device – fully compliant with the relevant standards EN 13241, EN 12604, and DIN/TS 18293:2024-11.
Normative Requirements for a Door
EN 13241 defines the general safety requirements for doors and barriers. One key requirement is preventing uncontrolled downward movement of the door. EN 12604 specifies that a sectional door must be designed to prevent unintended or uncontrolled movement of more than 300 mm. This is typically achieved with a spring fracture safety device—unless the operator itself provides a static holding torque that exceeds the door’s weight.
Our gearboxes have been tested according to DIN/TS 18293:2024-11 and fully meet these requirements.
GIGAsedo Operators: Powerful Performance and Certified Safety
The SOMMER GIGAsedo operators—available in both crank and emergency hand chain versions—easily meet these strict requirements. With a static holding torque of over 1000 Nm, they ensure maximum safety, even for very heavy doors.
Maximum Door Weight per Drum Size
Our tests show impressive results. Depending on the drum size, the following maximum door weights can be operated without an additional spring fracture safety device:
Drum diameter (Maximum door weight)
- 340 mm (650 kg)
- 219 mm (1000 kg)
- 159 mm (1390 kg)
- 133 mm (1660 kg)
- 123 mm (1840 kg)
- 115 mm (1920 kg)
- 84 mm (2600 kg)
With these outstanding holding torques, our customers not only save costs on a spring fracture safety device, but also gain efficiency and safety.
Only Exception: Unlocking from the Ground Level
One important exception remains: Operators that can be unlocked from the ground level must still be equipped with a spring fracture safety device.
Conclusion: Cost and Safety Benefits with GIGAsedo
Thanks to SOMMER's GIGAsedo operators, sectional doors can be operated without an additional spring fracture safety device in most cases – secure, compliant, and cost-effective. This gives our customers a significant price advantage without compromising on safety.
