Description
Грузова тележка 12 перемещаетс по стреле 7 с помощью тележечной лебедки 13, расположенной на поворотной платформе 2. Т говый капат 14 (фиг. 4) сходит с барабана лебедки 13, огибает ролик 15, проходит через блок 16 монтажной каретки, блоки 1719 стрелы и закрепл етс на грузовой тележке 12. Т говый канат 20 огибает ролик 21, проходит через блоки 22 и 23 монтажной каретки , блоки 24. - 26 стрелы и закрепл етс на грузовой тележке 12. Отклон ющие ролики 15 и 21, установленные на поворотной платформе, предназначены дл компенсации изменени длины т говых канатов 14 и 20 при складывании крана . Складывание крана из рабочего в транспортное положение производитс следующим образом. Грузова тележка 12 перемещаетс к оголовку стрелы 7 и закрепл етс на нем любым известным способом. Бащн 4 опускаетс гидроцилиндрамв 5, при этом отт жка 10 ослабл етс , а т га 11 нат гиваетс . После опускани башни 4 в горизонтальное положение (фиг. 2) и расстыковки замка, соедин ющего стрелу 7 с монтажной кареткой 6, включением тележечной лебедки 13 производитс пере.мещение стрелы 7 в поThe truck 12 moves along the boom 7 using the trolley winch 13 located on the turntable 2. The tug drive 14 (FIG. 4) comes off the winch drum 13, bends around the roller 15, passes through the carriage assembly 16, the boom blocks 1719 and fastens on the load trolley 12. The round rope 20 bends around the roller 21, passes through blocks 22 and 23 of the mounting carriage, blocks 24. - 26 booms and is attached to the load trolley 12. Deflecting rollers 15 and 21, mounted on a turntable, are designed to compensate for the change in the length of the rope 14 and 20 when folding the crane. Folding the crane from the worker to the transport position is performed as follows. The trolley 12 is moved to the tip of the boom 7 and secured to it by any known method. Bach 4 lowers the hydraulic cylinders 5, while the delay 10 is weakened, and the pull 11 11 is tightened. After lowering the tower 4 to a horizontal position (Fig. 2) and unlocking the lock connecting the boom 7 to the mounting carriage 6, switching on the carriage winch 13, the boom 7 is moved
