Ciągłe poszukiwania rozwiązań i nowoczesne narzędzia - tak powstają najlepsze jakościowo urządzenia bezpieczeństwa Wittur. Ograniczniki prędkości Wittur to komponenty bezpieczeństwa przewidziane zarówno dla dźwigów prostej konstrukcji jak i skomplikowanych aplikacji i rozwiązań MRL. Ograniczniki prędkości Wittur mogą wyzwalać na całym obwodzie co podnosi poziom bezpieczeństwa i zwiększa żywotność komponentu 
Wittur offers a wide range of car and counterweight frames. Modularly conceived, these components are very flexible in terms of rated load, height and width. The wide range of accessories includes safety gears, suspension pulleys, compensation chain and travelling cable hangers, allowing configurations suitable for different shaft layouts, lift designs and rated speeds. Wittur can also supply special frames for tailored projects.
Ciągły rozwój i badania leża u podstawy nowoczesnych rozwiązań Wittur w dziedzinie bezpieczeństwa. Zakres produktów: chwytacze jedno i dwu kierunkowe, progresywne i natychmiastowe. Katalog uzupełniają urządzenia zapobiegające nadmiernej prędkości w kierunku góra.
Zgodnie z EN81-1/2 A3 i EN81-21 A1 (nowe dźwigi w istniejących budynkach), nowe dźwigi zainstalowane po 1 stycznia 2012, muszą być wyposażone w system zapobiegający przemieszczeniu się kabiny z przystanku z drzwiami przystankowymi w niezaryglowanej pozycji i drzwiami kabinowymi nie zamkniętymi w tej pozycji.

The first ever certified automatic door with optical coupling
These door systems, based on optical coupling, are the right solution for all those situations in which mechanical coupling is not possible.
Both the car and the landing door feature linear belt traction operators, each with its own engine. They couple through an optical device, integrated into the engine SWS controller, allowing a misalignment up to 50 mm between the centers of the emitter and the detector. Being prEN 81-22 certified, SWS is ideal for inclined lifts; inclinations between 15° and 75° are allowed and, for complex installations, it’s even possible to have different inclinations from floor to floor.
A fully covered operator guarantees high IP ratings and protection degrees even in extreme weather conditions. A wide range of finishes, fire certifications and special solutions are available.
