1. Substructure adopts the modular mode, and blocks connect with each other by pins, which can realize to move quickly.
2. Mast is front open-face, “K” type mast. The five sections of mast is tower-type integral structure, can install with the crown block to transport together. The supporting leg is located at base of substructure. stability is good, It is raised and laid down by Drawworks power as a whole. 3. Transfer power though the bevel angle gearbox and the cardan shaft, and the rotary table power is from the cathead winchs chain box and cardan shaft, the structure is simple and easy to install. Drawworks is divided, the main of which is placed under drill floor, it adopts sealing structure, chain is force-feed lubrication, pneumatic tyre gear change and drum grooving.
