FIELD: transport.
SUBSTANCE: invention relates to logging machines, namely to logging machine manipulators. Proposed device comprises rotary roller bearing with its bottom stationary part rigidly fixed on self-propelled chassis and its top rotary part accommodating rotary platform that supports manipulator and platform horizontal turn mechanism to turn said platform with manipulator in horizontal plane about vertical axis. Platform horizontal turn mechanism represents blade hydraulic motor with its housing rigidly coupled with aforesaid roller support top part and furnished with a sector rigidly coupled with inner surface of the body. Said body has holes precisely mating the work fluid feed/discharge channels arranged in said sector. Inner part with blade is rigidly fixed with bottom stationary part of aforesaid rotary roller bearing. Central part of hydraulic motor inner part represents hollow tube.
EFFECT: simplified design and higher wear resistance.
