Lifting devices for residential, public and industrial buildings and structures, and more specifically, lifting and carrying systems for maintaining building facades, having rail or mast-type guides, which are arranged on the external wall of the building and equipped with teeth, and a lifting device with a drive including a motor with a gearbox, and a toothed wheel mounted on the drive shaft of the gearbox to engage with the teeth of the guides so that, when the toothed wheel rotates, the lifting device moves along the guides. The shapes of the guides duplicate that of the building, and they are attached to the building by brackets passing through the building facade and secured to load-bearing structures of the building. The lifting device has a platform, each edge of which is hinged to a frame connecting two carriages each having a system of guiding thrust rollers supported on the guides.
