FIELD: oil producing industry. SUBSTANCE: proposed pumping unit frame, mechanism for converting rotary motion into reciprocating motion, posts with fitted-on pulleys for displacement of hangers for sucker rods of two pumping units. Walking beam is arranged at opposite sides from frame. Walking beam is made with radial head provided with radial grooves for fastening the hangers, and is installed by means of hinge joints on one of posts for rocking relative to vertical plane and engaging with sucker rod hangers. EFFECT: increased capacity, reduced consumption of electric energy. 1 dwg
