The powerful garage door operator for maximum convenience
The marathon SL is a real workhorse: Our premium model can move doors up to 8 m wide.
Customised combination of products
The strengths of the operator and length of the track can be combined flexibly to customer requirements.
The carriage can be easily removed with the new track unit. The track is galvanised and powder-coated and therefore very long-lasting.
Accident prevention through electronically controlled force measurement
The operator learns on its own and runs in the currently most economical way thanks to the DPS (Dynamic Power System). It adapts to the environment and always moves at the same speed. For the operator, obstacles mean that it suddenly needs more force. In this case, it stops or reverses. This prevents injury and damage to property.
Alternatives to the ITA
Since you can also operate industrial gates with the operator, it is also very well-suited for commercial use. It is high-performance and is an economical alternative to the ITA.
Quick and easy installation
No annoying above-head work. Thanks to the conversion set (separate head), installation in underground garages is better and easier.
Optimal application of force through soft running
Efficient application of force guarantees controlled soft running in ramp form which prevents unnecessary power loss.
Connections for photo eye and TorMinal
Since all connections for safety-relevant accessories are already present, no additional control units are necessary.
Environmental and cost efficiency
Consumption of electricity and environmental impact are low thanks to the efficient ring core transformer.
