Pile extractor with suspended vibrator frame - has spring loaded anvils in frame for varying extraction force

摘要

The machine is for excavating and extraction from the ground of support elements used to make pile reinforced foundations. It hasa portal frame for supporting a vertically moving frame and a vibrator. The vibrator is mounted on the frame with elastic supports and is connected to the components to be extracted. This machine can be used for extracting large piles from the ground. The vibrator frame (5) is connected by flexible springs (9) to the out- of-balance vibration exciter (10). The frame has a number of spring-loaded anvils (11) for transmitting vibrations to the frame. These anvils are arranged at different levels for varying the impact force transmitted to the frame through anvil springs.
