Elfer has invented the SASS system (a system improving the feeling of safety) with a double purpose: to reduce the feeling of a close space while standing into the non panoramic lift cars, and to define a new perimeter, even if only virtual, of the lift car.
The space is moulded in a different way, with the aim of making it more fluid even if constricted into a shaft that in any case couldn't be different in terms of shape and dimensions. For this reason Elfer operates from a “conceptual” point of view, while “opening” the lift car to the shaft so that it's possible to bring into the lift car all that has always been hidden and has been feared.
The shaft walls and the lift car become an unique single element and the perception of attractive images makes the time spent into the lift becoming a pleasant moment.

...this system underline an interest from the planning and graphical point of view of the shaft walls outside the lift. Numbers for identifying the different storeys, continual wall drawings form the first to the last storey, famous sentences that can be read at every storey, shapes that thanks to the speed can become animated and so much more things could permit an new experience while going up and down, more curious, more quiet, and...
