Description

Чем упоры 8 и 9 повернуты к гидрбстойке. Дл  подготовки устройства к работе с помощью гидроцилиндра 5 придают гидростойке 4 вертикальное положение. Откидывают упоры 8 и 9, затем траверсу поворачивают с гидростойкой 4 на 90°. Выдвижением штока гидростойки 4 распирают траверсу в три верхн ка крепи. После этого захваты 13 с гибкими элементами 12 зацепл ют за стойки крепи и путем включени  гидроцилиндра 14 извлекают их сначала у крайней рамы, а затем средней. После извлечени  стоек с помощью гидростойки 4 траверсу с верхн ками опускают, извлеченные элементы крепи укладывают на платформу 2.Than stops 8 and 9 are turned to gidrbstoyka. To prepare the device for operation by means of the hydraulic cylinder 5, the hydraulic post 4 is given a vertical position. The stops 8 and 9 are folded back, then the yoke is rotated with a hydroresistant 4 through 90 °. By extending the rod of the hydraulic post 4, the traverse is pulled apart into three top supports. After that, the grippers 13 with flexible elements 12 are hooked onto the support posts and, by turning on the hydraulic cylinder 14, they are first removed from the extreme frame and then the middle one. After the posts are removed with the help of a hydraulic post 4, the traverse with the tops is lowered, the extracted support elements are placed on the platform 2.
