1.  Applications

    GSD-50 Drill (Large Diameter Engineering Drill Rig) is a kind of all-hydro-drill with swivel head. It is used in bridge, highway foundation, dam and industrial and civil construction engineering to make perfusion bore and other type holes. It also can drill hydrology holes.

2.  Peculiarity

  (1)Using all-hydraulic mode of power transmission, with high mechanization；

  (2)Using a double oil cylinder-chain multiplying machinery, high drilling efficiency and reduced labor intensity；

  (3)Adopt drilling of pump-absorbed reverse cycle, also can use drilling of normally direct-cycle；

  (4)Swivel head have four-shift rotate speed, that can meet different requests of various drilling technology；

  (5)With hydraulic replacement machine to walk, easily to replace；

  (6)Compacted and light structure, agile to move, and can work under high tension line or inside a workshop, or beneath subway.
