1) These drilling rigs are designed and manufactured in accordance with API Spec Q1, 4F, 7k, 8C and RP500, GB3826.1, GB3836.2, GB7258, SY6584 standards as well as "3C’’ compulsory standard.
2) These the drilling rigs consist of trailer-mounted main unit, drive system, drill floor, DP slide way, control system and auxiliary system, etc.
3) The drawworks and rotary table are driven by DC brushless – excitation motors, and the driving control is realized by digital AC-SCR-DC system.
4) The hydraulic disc brake is for main brake and FDWS is for auxiliary brake.
5) The derrick which is front- open type and two - section structure with an inclination angle or erective sections can be raised up or lain down and telescoped.
6) The substructure with the height of 5.5 m has a parallelogram integral structure with two sections supported by 6 setbacks, which can be raised spirally.
7) The structure is simple, but easy for installation, movement and the transmission is reliable.
8) Safety and inspection measures are strengthened under the guidance of the design concept of "Humanism Above All" to meet the requirements of HSE.
