7000m Drilling rigs

Description

The basic parameters, structure, design and manufacture are according with international general specifications, including API, IEC and HSE. Details of major equipment fully reflect the design concept of Health, Safety and Environmental Protection. Adopting module design, the drilling rig has a compact structure. With sound-proofing and noise-reduction design, the generator room can reduce the harm to environment and people as much as possible. The drilling rig is designed to work in ambient temperature of -20°C ~+55°C. All the systems and equipment adopt high-temperature resistant components and air-cooling method. The drill can adapt to the high temperature, desert, with more rain environments.
