Since 1977 Wittur has been providing the lift industry with versatile and high-quality doors. More than 30 years later Wittur is the leading company in the lift doors segment, with state-of-the-art technical solutions and unparalleled product range. Regardless of whatever your lift requires - a round door with panoramic panels rather than a straight or a folding one - Wittur can supply the best solution for your needs.
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.
Research for innovative solutions and rigid product quality control are key features of Wittur Safeties.
According to EN81-1/2 A3 and EN81-21 A1 (new lifts in existing buildings), new lifts installed after January 1st 2012 must be equipped with a system to prevent a car moving away from the floor with the landing door not in the locked position and the car door not in the closed position.

Medium speed and rise governor
OL35 / E / M
The OL35 detects overspeed by its flyweight mechanism and engages the safety gear on the entire circumference of brake mechanism.
This brake mechanism is pre-adjusted and limits the brake-force to protect the synchronization of the safety gear from excessive stress to the linkage.
