Modeling the swing of mobile loader cranes with anchor outriggers when operating on weak soils

The paper presents a dynamic model illustrating the swing of mobile machine on wheeled chassis equipped with loader crane and anchor outriggers during loading unloading operations. regards interaction effect outrigger anchoring device weak soil within system “load – devices soil”. Possible variants single multiple step compaction changes in its deformation characteristics area implementation are considered. impact gaps formed parameters boom is demonstrated as applied to full-scale crane-manipulator. rate tilt angle period increase operation an ground. initial stage gradually for soils characterized by until these reach some steady-state values determined stiffness. Awareness value amplitude achieved at end process enables reasonably assess risk overturning.
