FIELD: construction engineering. SUBSTANCE: device can be used for erection of vertical cylindrical large-capacity hot water collecting tanks. Side walls of reservoirs are made up of unified metal prefabricated components without turning them into rolls and without using additional scaffolding. Device incorporates central post located in center of reservoir. Mounted on post are swinging crane boom and erection platform which are turnable around central post. Additionally used are transition platform for double-side welding and inspection, unit for vertical movement and fixing of erection platform, unit for horizontal movement of erection platform around central post, pulling mechanism, unit for fixing of prefabricated components. EFFECT: high efficiency. |
