LPG loading arms

 features
FEATURES:
Loading arms are used in major storage terminals for the connection between tankers and storage. Gas and liquid LPG is tranferred from/to the terminal storage tanks through the arms.
When not in operation, the arm can be folded reducing the space utilization and at the same time the risk of being damage by a truck.
