CMU testing: types and subtle differences

CMU testing: types and subtle differences

Static testing refers to determining the strength characteristics of a structure under constant load over a period of time. For operating cranes, there are their own rules for conducting such tests. Firstly, the load of this CMU test exceeds 25% of its installed capacity. Secondly, cranes with multiple load characteristics are tested at the maximum load capacity or load torque position. If the robotic arm does not have a flight control mechanism, it will be tested during the flight set for it. In addition, in the KMU static test, the suspension rod is installed relative to the chassis at a position corresponding to the minimum stability designed for the crane, and the load is raised by 10-20 cm. In this case, if the robotic arm can withstand the load and the load does not decrease after 10 minutes, it passes the test. In addition, there are no cracks, residual deformation, or other damages on the equipment. In addition to maintaining the CMU of the applied load, check the force of the robotic arm to secure it to the chassis. The strength of the fasteners should ensure the safe operation of the entire machine to avoid tearing the CMU from the chassis during loading.
