The actively switching SENTIR Bumper safety contact bumper ensures a damage-free approach from the GSE to the aircraft. Mounted in the front of the vehicle, it detects any impact while operating. If a collision cannot be avoided the padded bumpers absorb the momentum of the vehicle itself and offer a crumple zone, so that the risk of damage is low. ASO’s SENTIR bumper is resistant to many substances and customizable in shape, size and color.
