К днищу сооружаемого резервуара 15 крепится центральная стойка 1 (при наличии в конструкции резервуара центральной стойки используется последняя) с закрепленным на ней опорным кольцом 2, на которое одним концом опирают в тре— 20 буемом положении опорный кронштейн 3, содержащий падающую защелку 5. Другой конец кронштейна опирается колесом 4 на днище резервуара. Тяговый трос одним концом присоединяется к приводу, зала- 2$ совывается на ролики 7 и крепится к рулону. Натяжением тягового троса 8 начинается разворачивание рулона, кронштейн при этом стопорится от вращения в сторону рулона падающей защелкой 5. Когда зо рулон приблизится к кронштейну 3, еще •не касаясь его, тяговый трос ослабляется и конец его крепится к щеке 6. Натяжением тягового троса кронштейн пере, водится в новое положение. Конец троса ₃$ отсоединяется от щеки 6 и крепйтся к рулону. Разворачивание рулона продолжается до тех пор, пока рулон не займет крайнее положение (фиг. 2). Тяговый трос отсоединяется от рулона~ и с его ₄₀помощью вытаскиваются через проем иа резервуара само устройство и катушки рулона. Затем трос опять присоединяется к рулону и производится окончательное разворачивание рулона.A central rack 1 is attached to the bottom of the tank under construction 15 (if the central rack is used in the tank structure), the support ring 2 is mounted on it, onto which the support bracket 3 containing the falling latch 5 is supported at one end in the required 20 position. The other end the bracket is supported by a wheel 4 on the bottom of the tank. A traction cable is attached to the drive at one end, a $ 2 jack is pushed onto the rollers 7 and attached to the roll. By pulling the pull cable 8, the roll unfolds, while the bracket stops rotating from falling towards the roll with the falling latch 5.
