- The robot will use a 20kW laser for coating stripping of commercial and military aircraft of any size
DEKRA, a well-known third-party inspection and testing organization in Arnhem, the Netherlands, will test the world's largest innovative laser-coated stripping (LCR) robot for LR Systems BV testing.
The robot developed by LR Systems will use a 20 kW laser to remove coatings from commercial and military aircraft of any size with maximum precision. In addition, the robot removal process is faster and cleaner than the methods used today, and can significantly reduce aircraft sluggish time on the ground.
Mr. Paul van IJsselstein, CEO of LR Systems BV, said: “I am very pleased that DEKRA will support our global LCR team and I believe that the development and launch of our first system will benefit from the unique DEKRA Dekai Group. Expertise in technical knowledge and experience. DEKRA's professional support can further add to our global robotics solutions in the maintenance industry."
DEKRA will participate in the entire testing and certification process, from safety performance assessment, component testing, and factory acceptance testing to the installation of the first LCR robot. Mr. Bert Zoetbrood, President of DEKRA's Global Business Unit for Product Testing and Certification, said: "Our commitment to safety means we further strengthen our services in innovation and high technology, such as EMC (Electromagnetic Compatibility), network security, functionality. Sexual safety testing, electrical safety, and international market access. Our support for LR Systems in the development and deployment phases of LCR robots is fully aligned with our vision. We provide globalization for every step of the development process for innovative products. Comprehensive service until new products successfully enter the market."
