FIELD: process engineering.
SUBSTANCE: set of inventions relates to machine building, particularly, to benches for coupling and breakout of downhole hydraulic motors. For this, hydropneumatic accumulator and pilot-operated check valve with decompressor is arranged in every chuck. External leak line is connected to inlet of working fluid flow divider made up of several sections of reversible hydraulic machine. Every section is articulated with two adjacent sections and equipped with anti-cavitation and reducing valves.
EFFECT: accelerated leveling of hydraulic cylinders.
