1. The whole unit structure is on the basic of petroleum drilling rig, and then the parts adopt the mature structure of the drilling rig; the power system adopts hydraulic and mechanism drive type with a high efficiency; the chassis adopts the special II class chassis or self-propelled type to meet the needs of the users.
2. An impact structure, high unitized degree and strong capacity of the movement, which can be transported for one truck, are easy for the installation and disassembly.
3. The mast adopts front-open single section or double section vertical structure without the guy-line, hydraulic lifted and lowered.
4. The drilling rig is operated in the condition of -35°~+55° environment.
5. The design and manufacture conforms to API SpecQ1, 4F, 7K, 8C and16C, performing the standard of GB/T 30216-2013 and GB1589-2016. The design idea of people orientated is adopted, intensifying the methods of safety protection and inspection to meet the needs of HSE regulation.
