Street furniture often includes scrolling advertising billboards. While the total number of billboards allowed in cities and towns tends to be more and more limited, scrolling billboards offer the perfect trade off between economical constraints and environmental concerns, by offering in a single space multiple advertising panels.
The street furniture concept requires an attractive design, with an outer shell often customized for each city, to produce a greater impact when placed on strategic sites and blend harmoniously into the surrounding environment.
The scrolling of several posters in a single billboard, where thinness is a critical parameter, is made possible through the use of tubular motorisation systems (motorised rollers), with diameters ranging from 115mm for the largest billboards (12m²) down to 57 mm for the smaller (2m²).
Operating day and night all year round, under the harshest temperature and humidity conditions, these motorised rollers demand an extreme reliability to perform around 4 million start/stop cycles per year during several years.
The motorized rollers are often associated with customized electronic drives to achieve smooth and accurate rotational motion.
