How can the rotary drilling rig not be pulled out of the ground?
It is better to use Jack jacking up method, that is, the jacking foundation of Jack shall be made next to the pile hole before using a jack so as to prevent the foundation from sinking. There is also a thorough method, that is, excavation method, because the pile hole is not very deep, but it entirely depends on the geology, if the formation is not good, it is limited.
Just to see today, our family is also the raise of drilling rig is the North 2030 also appeared now that you are out of it, I remember we immediately find is 50 ton crane and lifting the drill together if deep to please support faster time plus drowner,
What you describe is not very thin, but the long retaining cylinder, pumping, excavation, lifting (large crane or Jack) is a common method
I have also encountered the main winding wire rope broken, but not so deep as 8 meters. Try to connect the main winding wire rope, then put the power head in the lowest position, connect the power head and the drill pipe with wire rope, start the main hoist on the machine and start the power head at the same time. In this way, the power head, the pressure cylinder and the main hoist are combined to raise the drilling rod. Good luck
