Firstly, the assembly must be completed. Once assembled, heavy objects should be placed on it to test the lifting capability and stability of its various components. Strictly prohibit placing heavy objects exceeding its load capacity, as any accidents caused by this could be extremely serious.

When operating the gantry crane, ensure it rises and descends steadily without twisting. It is essential to have a professional person on the ground providing unified and orderly instructions. Operators follow the commands to execute the operational steps, thereby ensuring a smooth lifting process.

No person is allowed to stand or walk beneath the heavy object before or during the lifting process to prevent any safety accidents. Operators should ensure there are no people below before proceeding with the lifting operation.
