4.卡特彼勒(Caterpillar)柴油机与艾里逊(Allison)液力传动箱匹配合理，传动效率及可靠性高。绞车和转盘可选用电驱动方式。
      5.主刹车可采用带刹或盘刹。辅助刹车可采用气动水冷盘刹、水刹车或电磁涡流型式。
      6.转盘传动箱可实现正倒档，适应各种钻杆扣旋转作业，反扭矩释放装置保证钻杆变形能安全释放。
     7.井架为前开口、双节套装前倾式桅形井架，或直立双节套装井架，液压起放及伸缩。
      8.钻台为两体伸缩式或平行四边形结构，便于运输吊装，台面尺寸和高度可按用户要求设计。
      9.完善的固控、井控、高压管汇系统及发电机房、机泵房、值班房配套设施，可满足用户不同要求。
      10.采用“以人为本”设计理念，强化安全保护和检测措施，HSE规范要求。

 

* This kind of 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.
    * The whole rig has a compact structure, which requires a small installation space due to kits high integration.
    * The heavy-duty and self-propelled chassis: 8×6、10×8、12×8,14×8、14×12、16×12 and hydraulic steering system are utilized respectively, which ensures the drilling rig a good passage and cross-country capability.
    * The reasonable assembly of CATERPILLAR engine and ALLISON transmission box can ensure high driving efficiency and working reliability.
    * The main brake adopts hydraulic disc brake or band brake and Air brake or hydromatic brake or FDWS brake can be applied as auxiliary brake.
    * The rotary table transmission box can realize forward-reverse shift, which can be suitable for all kinds of DP rotary operations, and the anti-torque releasing device can be used to make the DP deformation force released safely.
    * The mast, which is front –open and double-section type with an inclination angle or erective double-section type, can be erected or lowered and telescoped hydraulically.
    * The drill floor is twin-body telescopic type or with parallelogram structure, which is convenient for easy hoist and transportation. The height of the drill floor can be designed accrording to the client’s requirements.
    * The perfect configurations of solid control system, well control system, high-pressure manifold system, generator house, engine & mud pump house, doghouse and other auxiliary facilities can meet user’s different requirements.
    * Safety and inspection measures are strengthened under the guidance of the design concept of “Humanism Above All” to meet the requirements of HSE.
