The invention relates to installation work in construction, in particular to the installation of maintenance for high-rise structures.

The purpose of the invention is the expansion of technological capabilities and increased safety of work.

The drawing shows schematically a device for servicing high-rise structures, a general view.

The device for servicing high-rise structures includes a self-propelled crane 1 with a turret 2 and a boom 3, a self-lifting cradle 4 on which a friction-drum winch 5 and a centrifugal catcher b are installed, which interact with cargo and safety ropes 7 and 8 with loads 9 for tension these ropes. The upper ends of the cargo and safety ropes 7 and 8 are fixed directly on the axis 10 of the boom tip 3 of crane 1, and the lower ends of the cargo and safety ropes are passed through the tap-off units. One pair of 11 tap blocks is mounted on the cradle below the friction drum winch 5 and the centrifugal catcher 6. Another pair of 12 tap blocks is located under the tip of the boom of the crane. At the same time, the ends of the cargo and safety ropes are stored in blocks of the tackle, in which the fixed blocks 13 are attached to the axis of the tip of the lash 2 of the crane 1, and loads 15 are attached to the moving blocks of the 14 tackles to tension the load and safety ropes 7 and 8. Cargo and safety ropes 7 and 8 interact with the deflecting cable 16 by means of branch units 17 mounted on it.

The lower end of the deflection cable is attached to an additional winch 18 installed in the crane cabin 1.
