The 700-bar steel double-acting 300-ton hydraulic hollow jack can be equipped with a two-way manual oil pump or a two-way electric oil pump. Because of the through hole in the middle, the hollow jack not only has the lifting capacity of a general hydraulic jack but also has the stretching and tensioning functions that the ordinary jack does not have. The through hole allows cables, steel ropes, and other shafts to pass through. The hollow roof has double functions and hydraulic retraction.
