The analysis of studies of the work processes of energy-saving hydraulic drives and devices was carried out in order to identify effective ways to reduce the dynamic loading and energy intensity of highly loaded technological machines and equipment. When studying the working processes of an energy-saving pneumohydraulic fifth wheel coupling of a timber tractor with a trailer, it was found that the recuperated power was 5.1-5.9 kW, and the average acceleration of the semi-trailer was 0.8 ... 0.81 m/s2. The energy-saving device of the Amkodor 208V front loader, which includes two torsion springs installed between the frame and the boom, reduces energy costs by 26%. The paper presents studies on energy saving during the operation of a hydraulic press with a pump-accumulator power supply. The results of studies of the energy-saving hydraulic drive of a forest manipulator and a chokerless skidding grip are presented. The energy-saving hydraulic drive of the manipulator column makes it possible to reduce the energy consumption of the column rotation by 25% and increase the productivity of the manipulator by 14%, and the chokerless grip hydraulic accumulator stores power in the range of 1.7 ... 2.1 kW. It is concluded that it is expedient to conduct further studies of the dynamics of energy-saving hydraulic drives of load-lifting mechanisms of manipulators of heavily loaded forestry vehicles.
