Log Unloading at Logging Enterprise Berths

In the development of market economy in Russia, main trend log processing industry is implementation cutting edge technology and effective innovation order to boost labor productivity reduce production cost on basis environmentally friendly rational use timber resources. Taking into account important role water transport used for rafting, problem efficiency loading unloading flat rafts at berths quite urgent. The current research considers ways increasing multi-row logging enterprise berths. aim this present results experiments berth. these experiments, a load lifting crane equipped with special grippers was During duration sequence from berth defined applied calculated by Northern (Arctic) Federal University named after M.V. Lomonosov Volga State Technology based laboratory statistical obtained data. We also carried out strength test gripper transposition lengthy onshore yards force fluctuation amplitude oscillation period during process raft load-gripper ground higher 11–33% than water, facilitated damping capacity. Based research, durability grippers, patented Russian Federation under No. 2476366 2526767, experimentally tested. hypothesis theoretical calculations equitability gross distribution applicable general purpose apparatus four choker grapples confirmed. certainty assumption amounted 97.6%.
