Improving the efficiency of manipulator-type machines with an improved hydraulic drive

Abstract

The article considers the possibility of increasing the efficiency of manipulator-type machines when harvesting wood by increasing the productivity, energy efficiency and reliability of the hydraulic equipment used. A combined method of transporting timber from logging sites by road and water transport using equipment with an improved hydraulic drive of the manipulator is proposed. The issue has not been worked through before. Using the example of the Northwestern Federal District, the author considers the development of forest areas located in the upper reaches of small and medium rivers. For the first time, original hydromechanical dampers and energy-saving devices are used in hydraulic drives of manipulators of forest machines to reduce dynamic loads and energy consumption for loading and unloading timber. This increases the efficiency of the use of manipulator-type machines, creating mobility, reducing equipment costs, the time spent waiting for unloading on sites for further rafting or shipment. The development of forest areas in a combined way will reduce capital investments for the construction of transport routes at the border of waterways by at least 3 times. All this will reduce the cost of harvesting in general and eliminate the use of additional loaders.
