One of the most effective ways to enhance operator ergonomics is by removing visual obstructions, particularly overhead guards. Replacing overhead metal grids with polycarbonate significantly improves upward visibility, enabling safer and more precise handling.
While removing the grids may seem counterintuitive from a safety perspective, polycarbonate offers a key advantage over glass: it absorbs impact without shattering. Aikon® glazing has passed the key overhead-protection tests, including the ISO 6055 dynamic test (a 45 kg object), the ISO 6055 impact test (weights from 340 to 1,360 kg) and the ISO 16936 repeated ball drop test (a 4.11 kg object). It is also tested to FOPS Level 1 and 2 under ISO 3449, which includes a 227 kg falling-object test at Level 2.
This is clearly demonstrated in the impact resistance comparison below:
As shown, normal float glass has minimal impact resistance (rated at 1), whereas Aikon® PC Hard offers 200 times greater resistance, and the Aikon® PC Hard laminated variant doubles that, reaching an impressive rating of 400.
A clear and undistorted view is essential for precise load handling and operator awareness. The Aikon® High Optical Quality is tested to DIN 52305 standard to ensure consistently sharp visibility.
Its low distortion values outperform those of general-purpose polycarbonate, and in many applications, glass, especially in formed or curved components, where glass can create internal reflections or glare.
Impact resistance isn’t just about safety – it’s also about durability and maintenance. When a stone hits a standard glass window, it may not shatter immediately, but even a small crack means the pane has to be replaced. With Aikon® polycarbonate, that same impact won’t cause cracking – the window stays intact and in use. This means less downtime, fewer replacements, and significantly lower maintenance costs over time.
In addition to impact resistance, cabin windows are exposed to constant wear from debris, wiper blades, or frequent cleaning, all of which can reduce visibility over time. Aikon® glazing features a durable hard coating that resists surface abrasion, helping to maintain optical clarity and extending service life – even in demanding environments.
Discolouration is a common concern with polycarbonate materials, especially if they are exposed to sunlight. Hard-coated Aikon® polycarbonate includes advanced UV protection that prevents yellowing and maintains optical clarity. This is especially beneficial for machines operating in mixed indoor and outdoor settings.
Forklift cabins may come into contact with a variety of chemicals, such as hydraulic oils, lubricants, fuels, and alcohol-based cleaning agents. Aikon® glazing retains both its mechanical and optical properties under chemical exposure. This resistance ensures the material remains clear, stable, and easy to maintain over time, supporting both functional performance and user convenience.
