FIELD: mining.
SUBSTANCE: draw work comprises a facility for winding of a rope, which is placed in the centre of a shaft, one or several supports, many motors and the main frame. The shaft has one first end and one second end and rotates in one first direction and in one second direction, opposite to the first direction. The facility of rope winding has at least partially mainly the cylindrical shape. Supports serve to support the main shaft in process of rotation. Multiple engines provide for rotation of the shaft and the facility for winding of the rope in the first direction and in the second direction. Supports and engines are fixed to the main frame. Engines are installed at both sides of the facility for winding of the rope and are connected to them without elements of speed rotation, with direct transfer of torque rotation to the shaft.
EFFECT: increased efficiency and reliability of operation of drilling rigs.
