The land loading and unloading arm is a piece of equipment used for the loading and unloading operations of media such as liquids and gases on land. The following is an introduction to this product:
Typical Models of Land Loading Arms:
Model | Loading Position | Application | Single/Double Pipes | Liquid Flange Direction | No. of Swivel Joints | Connection Type |
AL1401 | Top | Loading | Single | Upwards | 4 | Open |
AL1402 | Top | Loading | Single | Downwards | 4 | Open |
AL1412 | Top | Loading | Double | Downwards | 4/5/8 | Open |
AL1512 | Top | Loading | Double | Downwards | 10 | Closed |
AL1513 | Top | Loading | Single | Upwards | 4 | Open |
AL2503 | Bottom | Loading/Unloading | Single | / | 5 | Closed |
AL2543 | Bottom | Loading/Unloading | Double | / | 10 | Closed |
AL2404 | Bottom | Loading/Unloading | Single | Downwards | 4 | Closed |

- The pipeline is equipped with a swivel joint to achieve three-dimensional movement of the arm;
- The spring cylinder balance system balances the bending moment generated by the outer arm and front-end components;
- The vehicle connection port of the outrigger can be connected with a quick coupling or a loose flange as selected by the user;
- The main sealing ring of the swivel joint is of the structure of reinforced PTFE + stainless steel spring steel clamp, which has good self-lubrication and wear resistance and can achieve self-compensation during wear.
- A spring balance mechanism is adopted to balance the gravitational moment of the outer arm, and the unbalanced moment is less than 5Kg.M, making the operation light and labor-saving.
- An anti-static device is equipped, which can effectively eliminate the stray charges generated by the liquid flow during the loading and unloading operations.
- An inner arm locking mechanism is equipped to effectively reset the arm when it is not in use.
- It is simple to install and maintain, and convenient for repair.
