The editor of the quantitative loading and unloading manufacturer explains the features of the AM63 manual marine loading and unloading arm:

1. Only the pressure inside the conduit and the weight of the medium act upon the rotating union and the pipeline.

2. The supporting system features large-diameter rotating supports, effectively reducing friction resistance and ensuring easy operation.

3. The diameter of the pipeline in the rotary union box is standardized.

4. The pipeline floats on the support system, effectively eliminating additional stress caused by temperature changes.

5. The balancing system ensures that the loading and unloading arm remains in a balanced state at any position, achieving balance during the movement of the inner and outer arms through an adaptive counterweight mechanism.
