Loading/Unloading arm

About loading arm

Loading arm is also known as liquid loading and unloading arm, It is composed of rotary joint, inner arm, outer arm, drop tube (mainly for land use), three-dimensional joint (mainly for marine use), balancer, control system and other components, mainly used for loading and unloading for automobile tankers, train tank cars.

Features

1. Compared with the old-fashioned hose connection, the loading arm adopts a hard connection method, coupled with safety devices such as emergency disengagement, which can effectively prevent the occurrence of pipe bursts, breakage, etc., and It has high safety;

2. The swivel joint adopts advanced double-roller technology, 360-degree steering is light, safe and leak-free, and easy to maintain;

3. Operation is flexible, and the spring cylinder balancer that is balanced at any time makes the loading and unloading arm easy to operate and labor-saving. A single person can complete the connection between the pipeline and the tanker, and easily control the loading and unloading process;

4. Customize the size according to the customer's loading and unloading range requirements, and follow the tank truck within the normal moving range of the tank truck during the loading and unloading process;

5. The pipeline is made of carbon steel, stainless steel, aluminum alloy and other materials according to different liquid media, and has a long service life;

6. Pipelines can be lined with PTFE and equipped with heat tracing devices, which can transport a variety of special liquid media, such as hydrochloric acid, asphalt, crude oil, etc.; 

7.  Adopt sealed loading and unloading operation, it can reduce the volatization of the medium and reduce the pollution to the environment.

Loading arm type:

1. According to the usage application, it is divided into: land liquid loading and unloading arm, marine liquid loading and unloading arm,  Tank truck loading arm, train crane tube, etc.

2. According to structure, it is divided into: top loading and unloading arms, bottom loading and unloading arms, open loading and unloading arms, closed loading and unloading arms, etc.

3. According to the medium, it is divided into: gasoline and diesel arms, methanol arms, ethanol arms, liquid chlorine arms, liquid ammonia arms, crude oil arms, etc.
