1.The drawwork is single-shaft with grooved drum structure, has less spare parts, small cubage, light weight compared with the products of the same kind.
2.The drum shaft is driven by the gear reducer which power originate from a DC or AC-VF motor,it can also be driven by compound operation of two motors. AC-VF motor make the drawworks has a wider timing scope, the speed can be regulate smoothly between 0-140Hz.
3.High transmission efficiency gear, small oscillation, low noise, long service life.
4.The main brake of the drawworks is hydraulic disc brake while the auxiliary brake is energy- consumption brake or EATON brake.
5.The drawworks is equipped with independent numerical-control AC-VF transmission device and automatic control system(ACS),it can feed bit automatically; Real-time monitoring and analysising of bit feeding and infixing, get the optimal drilling.
