Characteristics and classification of loading arm

Crane tubes, also known as liquid loading and unloading arms, are composed of rotating joints, inner arms, outer arms, vertical pipes (mainly used on land), three-dimensional joints (mainly used on ships), balancers, control systems, and other components. They are mainly used as loading and unloading equipment for liquid media in car tank cars, train tank cars, or tank ships.
Crane tube characteristics:
Compared to the old-fashioned hose connection, the crane tube adopts a hard connection method, coupled with safety devices such as emergency release, which can have a certain effect in preventing the occurrence of tube explosions, fractures, and other situations, and has high safety;
The rotary joint adopts advanced German double roller track technology, with a 360 degree steering that is lightweight, safe and leak free, and easy to maintain;
The flexible operation and balanced spring cylinder balancer make the loading and unloading arm easy to operate and labor-saving. A single person can complete the connection between the pipeline and the tank car, making it easy to control the loading and unloading process;
Customize the dimensions according to the customer's loading and unloading range requirements, and during the loading and unloading process, follow the tanker within its normal movement range;
The pipeline adopts materials such as carbon steel, stainless steel, and aluminum alloy according to different liquid media, with a long service life;
The pipeline can be lined with tetrafluoroethylene and equipped with heat tracing devices, which can transport various special liquid media, such as hydrochloric acid, asphalt, crude oil, etc;
Adopting a closed loading and unloading operation can reduce the volatilization of the medium and reduce environmental pollution;
Crane tube classification:
1. According to usage scenarios, it can be divided into: land liquid loading and unloading arms, ship liquid loading and unloading arms, car crane pipes, train crane pipes, etc
2. According to the loading and unloading form, it can be divided into: top loading and unloading crane tube, bottom loading and unloading crane tube, open loading and unloading crane tube, closed loading and unloading crane tube, etc
3. According to the conveying medium, it is divided into: gasoline and diesel crane pipes, methanol crane pipes, ethanol crane pipes, liquid chlorine crane pipes, liquid ammonia crane pipes, crude oil crane pipes, etc
