Description

Изменение положени крана 1 но высоте производитс механизмом 2 подъема крана после освобождени последнего от креплени боковыми раст жками 7 (см. фиг. 3).The change in the position of the crane 1 to the height is made by the crane lifting mechanism 2 after the latter is released from the attachment by lateral stretches 7 (see Fig. 3).

Дл горизонтального перемещени крана 1 без предварительного спуска его на отметку земли против предполагаемой оси подвеса крана 1 дополнительно устанавливаетс и крепитс второй комплект корного приспособлени 5, к которому присоедин етс грузовой канат механизма 3 подъема груза. После этого кран 1 освобождают от кренлени боковыми раст жками 7 и, измен с помощью механизмов 2 и 3 свободные длины гибкой подвески 6 и грузового каната, кран 1 устанавливают в положение, отличное от первоначального как по фронту, так и по высоте здани .For horizontal movement of the crane 1 without first descending it to the ground level against the intended axis of suspension of the crane 1, the second set of the crusting device 5 is additionally installed and fastened to which the cargo cable of the load lifting mechanism 3 is attached. After that, the crane 1 is free from inclined lateral stretching 7 and, having changed the free lengths of the flexible suspension 6 and the load rope by means of mechanisms 2 and 3, the crane 1 is set to a position different from the initial one both along the front and in the height of the building.

После этого гибка подвеска 6 отсоедин етс от креплени на корном приспособлении 5 и закрепл етс на втором комплекте корного приспособлени , а грузовой канат механизма 3 подъема груза освобождаетс от креплени на корном приспособлении.Thereafter, the flexible suspension 6 is detached from the attachment on the root fixture 5 and secured on the second set of the core attachment, and the load rope of the load lifting mechanism 3 is released from the attachment on the root attachment.

Кран 1 после закреплени боковыми раст жками 7 вновь готов к работе.After fixing the side strands 7, the crane 1 is again ready for operation.
