FIELD: mining.
SUBSTANCE: invention relates to drilling bases with platforms, which are intended for installation of a mobile drilling unit in the area of drilling base during drilling and maintenance of oil and gas wells. Drilling base with lifting platform for mobile drilling rig is installed on drilling site. On one side the lifting platform is connected to the drilling base by means of hinges installed at the required height from the level of the drilling site. On the other side, the lifting platform is connected to the lifting and lowering hydraulic cylinders, which are located on the support plate rigidly fixed on the drilling site. A wedge-shaped ladder is installed on the drilling site so that its end face adjoins the end face of the downward side of the lifting platform.
EFFECT: simplified design of the lifting platform.
