How rain affects sensors
Infrared and laser sensors work on optical principles. In rain or humid weather, water stains, mud or dust on the sensor lens can affect detection range and sensitivity, making it harder for the system to detect people in the danger area reliably.
A few simple habits
Quick checks before driving
- Check that the sensor lenses are clean and wipe them with a soft dry cloth if needed
- Check that brackets and sensors are secure and have not been knocked out of position
- Test the tail lift once to confirm the system detects and stops correctly
During operation in the rain
- Do not scrape the lenses with your hands or hard objects – this can leave scratches
- If the system behaves abnormally, stop work immediately and arrange an inspection
- Keep the operating area well lit so operators can watch their surroundings
Regular maintenance
- Perform a visual check every month to confirm the sensors are clean, undamaged and the wiring is secure
- Have a professional technician carry out a full inspection and functional test every six months
Bottom line
Sensors need a clear view to be reliable. Simple cleaning and a quick pre-drive test greatly reduce the risk of system faults during the rainy season. If a fault does occur, contact a qualified technician – never continue operating a tail lift with a faulty safety device.
