Drilling equipment technology for special requirements (PDF, 4300 KB)
The accomplishment of tasks related to drilling technology becomes increasingly challenging. Solutions are required which are both economically and technically safe. Due to this, it is necessary that the drilling equipment technology can be specifically adapted to the single cases of application. In addition, the equipment technology has to be able to perform a possibly high number of possible tasks. In the following article, the new developments regarding universal drilling units will be described by means of practical examples.
