Speaking about this, it is worth mentioning the case of the successful application of such a mechanism for magnificent chandeliers of the Mariinsky Palace in Kiev. During the restoration, light lifts for all 14 chandeliers were installed. These are technical devices with which all chandeliers in the palace are mounted and connected. For each lamp weighing from 150 to 600 kg, a light lift was made and installed. At the right time, each chandelier can be lowered down, replace the light bulbs, clean from dust, check fit, and then raise up to the ceiling. You can learn more about this here. The company "PAITEKS", which has implemented this project, assists to anyone who needs to install and connect a heavy chandelier. We design and manufacture lifts for stable and uninterrupted work for many years. Contact!
