MGJ-50 ANCHORING DRILLING RIG

MGJ-50 is top-drive head, mechanical transmission, hydraulic feeding and hoisting anchoring drilling machine.                                                    MGJ-50 ANCHORING DRILL                                           

                                              

MGJ-50 is mainly used for soil and rock anchoring and high pressure jet-grouting. It is suitable for consolidating and strengthening foundation of highway, dam and retaining wall, preventing soil and rock from collapsing, supporting in deep foundation pit and underground engineering construction projects.

        • Top head drive, mechanical transmission, hydraulic feeding and hoisting.

        • Drilling angle: any angle in one section(drill with motor power)

        • Top-drive head stroke: 2300mm with normal mast; 1500mm with shorter mast; 1200mm 

           with shortest mast.

        • Top-drive head has two speed series type: one is low speed series for down-hole hammer

           drilling; The other is high speed series for rotary drilling.

        • Top-drive head controls the mast up and down, simple structure, safe and reliable.

        • Skid frame or wheeled frame for choice.
