Drawworks is the core part of drilling rig. It is mainly used for feeding drilling tools .lifting or laying down mast, triping in and out drilling pipe, running in casing operation and so on. Technical Features 1. Electric single shaft drawworks：It is composed of the AC or DC motors, gear reducers, hydraulic disc brake, the drawworks frame, the drum shaft assembly, automatic bit feed equipment and drawworks control system. Compare with the similar drawworks, the parts are few, the volume is small, the weight is light; The drum shaft is driven by a DC electric motor or a AC-VFD electric motor through the gear reducer (It is also possible that two motors drive gear reducer), which may realize the smooth velocity modulation in the 0~140HZ scope. Use the two-stage speed gear reducer transmission, the transmission efficiency is high, the vibration is small, the noise is low, the service life is long. Main brake is hydraulic disc brake, auxiliary brake is dynamic brake or EATON brake. The drum is equipped with Lebus rope groove, has the independent digital control AC-VFD and the computer automatic control system, which may realize automatic bit feed. Trip-in operating and drilling are monitored and analyzed on the real-time, which realizes the best drilling. 2. DC motor drive chain drawworks: It is driven by DC motor , has dividing type or integral-type structure; The drum high speed end, the drum low speed end are equipped with the ventilated pneumatic tube clutch. Main brake is hydraulic disc brake, auxiliary brake is electromagnetic eddy current brake. A
