At the drilling site, provide a place for the installation of a backup air defense console, in the driller's cabin, or in the immediate vicinity of it.Provide a block-box for watch rest (equipped with ventilation, heating, 220 V socket and lighting) with an entrance with a working platform.Place the rotor table in the same plane (at the same level) with the floor of the working platform. The covering of the rotor table and the drilling (working) platform in the service area of the setbacks must have anti-slip properties. The rotor drive is controlled on the basis of an asynchronous AC motor with frequency regulation.Shelter of the drilling site is made of metal with a vertical arrangement of panels (at least 6 m high from the floor of the drilling site) and a minimum number of assembly and transport units.
