This type of environment requires a certain level of flexibility as exhibition stands and display items are required to be frequently moved around to cater to the required aesthetics of different schemes and shows. The installation or maintenance of high level fixtures after these schemes have been finalised can often incur vast disruptions and costs.
Through the installation of raise and lower technology these sites can be maintained without any further costs or disruptions. For example a large back drop graphic can be installed or a blown bulb can be safely replaced at ground level without having to move any ground level fixtures or stands.
