[0002] The testing machine is a precision testing instrument that measures the mechanical properties, process properties, internal defects and dynamic imbalance of rotating parts of metal materials, non-metallic materials, physical properties, mechanical parts, engineering structures, etc. under various conditions and environments. Before the test, the test piece needs to be assembled on the testing machine. This process usually involves manually lifting the test piece and moving it to the assembly position of the testing machine and installing it. The labor intensity of the tester is high. When testing large-mass test pieces, a crane is also required to transfer and install the test piece. However, the structural space size of the testing machine itself limits the use of the crane, making the installation of the test piece very difficult and the installation efficiency low. Especially for the static fatigue testing machine, it has no device to assist the installation of the test piece, and the installation efficiency is low, which prolongs the cycle of the static fatigue test and wastes manpower and financial resources.

Its installation is not limited by the structural space size of the test machine itself, which not only makes the support more stable and safe, but also can perform height adjustment according to the different heights of the installation surface of the test machine.
