Description

щими лапами 5 выше отрегулированного происходит проскальзывание зубчатого венца 11 относительно стуницы 10, а челюсти 4 продолжают движение до полного заглублени  под пень. С помощью домкратов 2 пень извлекают из земли.with the paws 5 above the adjusted one, the crown ring 11 slips relative to the stunit 10, and the jaws 4 continue to move until they are completely buried under the stump. With the help of jacks 2 stump removed from the ground.

При этом пень или расколотые челюст ми части его надежно удерживаютс  лапами 5 и челюст ми 4. Затем включают устройство дл  Естр хивани  (очистки) пн  от грунта. Очищенный neiHb перенос т стрелой 17 на волок или груз т в прицеп. Челюсти 4 раскрываютс  и привод т в движение подгребающие лапы 5. Ввиду предыдущего проскальзывани  в приводе лап 5 последние придут в исходное положение с некоторым опережением и упрутс  своими тыльными сторонами в силовую раму 1. Снова происходит проскальзываниеAt the same time, the stump or the broken jaws of its parts are securely held by the paws 5 and the jaws 4. Then they turn on the device for Esthivan (cleaning) of the soil. Purified neiHb is transported by boom 17 onto the fiber or loaded into a trailer. Jaws 4 are opened and the raking legs 5 are set in motion. In view of the previous slippage in the drive of the paws 5, the latter will come to their original position with some advance and put their backs on the load frame 1. The slippage occurs again.

привода лап до момента полного раскрыти  челюстей 4. Дальше цикл работы повтор етс .the paws are driven until the jaws are fully opened 4. Then the cycle of operation is repeated.
