The drawworks is double- drum type, with which the hydraulic disc brake is equipped as the main brake and air water-cooling disc brake (Model EATON WCB324) is equipped as the auxiliary brake.
The derrick which is a frontopen type and has a two-section structure with an inclination angle or erective sections can be lifted up or fallen down and telescoped.
The substructure has a parallelogram integral structure for easy transportation and installation, which can be risen by 6 setbacks spirally.
This kind of drilling rigs with desert adaptability design also have good anti-dust and high/low- temperature-proof performances.
Safety and inspection measures are strengthened under the guidance of the design concept of “Humanism Above All” to meet the requirements of HSE.
