При изменении выпета стрелы 5 дви- ратель 11 через редуктор 10 вращает установленную на валу 8 шестерню 7, котора взаимодействует с зубчатой рейкой 6. Рычаг 1 поворачиваетс и т га 4 измен ет выпет стрелы 5, Штанга 12 обеспечивает вертикальное поло- жение корпуса редуктора 10.When changing the boom 5, the engine 11 rotates the gear 7 mounted on the shaft 8 through the gearbox 10, which interacts with the gear rack 6. The lever 1 rotates and the pull 4 changes the boom 5, the rod 12 provides the vertical position of the gearbox 10 .
