The analysis of the study of the dynamics of hydraulic drive of forest manipulators shows that work processes of column rotation mechanisms are accompanied by large dyna-mic loads that cause sudden changes of fluid pressure in the start-up and braking modes. The most effective are energy efficient hydro-pneumatic actuators of manipulator column that can recover energy during transient conditions and return some of the energy back into the system. A mathematical model of the operating modes was designed.
