Landing stage reducer principle is "prime mover - Links - Reducer - Links - machine" that is lifting power connection by means of transfer to the working machine. Reducer operation often appear the problem of poor bearing capacity, according to the analysis reducer principle, we can reducer bearing capacity factors summarized in the following three points.
Landing stage belonging to the prime mover and work machine reducer affect carrying capacity, due to external factors, load inhomogeneity, they will bring an external load reducer. Depending on the type of motivation, landing stage work machine characteristics can be divided into uniform and stable, the impact of mild, moderate impact, a serious impact on four. Steady load generator, light, light lift centrifugal pump are stable; heavy pump, piston pumps and other secondary effects; lifting devices, single-piston pump moderate impact; shovel, a serious impact rig. Landing stage and working machine prime mover has different characteristics of different types of load capacity factor is the impact reducer.
