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 move together. The supporting leg is located at base of substructure. stability is good, It is raised and laid down by Drawworks as a whole.
3. The rig is equipped with frequency conversion（ VFD） and MCC system. Frequency conversion （VFD） is used to control AC frequency conversion motor and the automatic bit feeding motors of rotary table; MCC is used to control other devices.
