Product Profile of Heavy Duty Rotary Drilling Rig
Heavy duty rotary drilling rig is specially designed and built for carrying out works requiring large bore diameters at great depths. The drilling rig can be equipped with different rotaries with different torque values depending on job requirements. Rotary drilling rig can exert a maximum nominal torque of 800 knm for insertion and extraction on the casing tubes. Heavy duty rotary drilling rig is also available with a crowd winch system [thd] which allows a longer stroke along the lenght of the mast, therefore longer casing sections may be used when drilling.
