自1977年来，威特就开始为电梯行业提供多功能、高品质的轿厢门。设计灵活，加上通过了一系列认证，使威特层门能够适应各种应用。有多种表面装饰和规格，因此能适合各种环境：从住宅到高档写字楼、从外部设施到豪华的水上项目、从工业建筑到医院。
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.
创新的解决方案研究和严格的产品质量控制是威特安全部件的主要特色。产品系列包括不定向/双向同步和渐进式安全钳。也可提供上升轿厢超速保护装置。
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.
所有井道附件对于保证电梯的正常运行和使用寿命都是至关重要的。这正是威特提供以下各种附件的原因：

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.
