Home > PRODUCT > Loading Arm RC Hydraulic Marine Loading Arm is a typical rotary counterweight marine loading arm. All of the vertical load and overturn moment should be supported by the base riser and supporting device to make the pipeline and the swivel joints free in theory. It can be maneuvered neatly by hydraulic cylinder in three directions, and the balance system consist of a pantograph for transmitting balancing loads from the outboard arm to the secondary counterweight .   Cryogenic loading arm is a new kind of marine loading arm which is used for conveying some cryogenic media such as LNG, ethylene and so on. Materials used for the main pipeline mainly depend on the temperature of products. The supporting structure of the arm is designed specially to prevent it from contacting the cryogenic pipeline, and to avoid the material performance changing in the condition of cryogenic temperature, such as cold shortness. The swivel joint, which is the key part of the loading arm, is also designed specially to make the whole six pieces of swivel joint cycled by Nitrogen gas. In this case, it can put the vapor out of the swivel joint to avoid icing in the race way of swivel joint and protect the race way from being broken. . FB Marine loading arm is full balanced in all positions with two independent counterweight systems. It is a self-support structure. The pipeline and the swivel joints endure not only the pressure from the media but also the gravity and the overturn moment of all load. It is usually used on the river wharf and the small tanker. Arm On Vehicle loading arm consists of two parts: the marine loading arm connected with vessel and the land loading arm connected with the local pipeline. It can make the loading arm work movably in order to ensure all loading facilities can leave the site timely after loading or unloading. Therefore, enough space can be saved to do other work; all the power used to operate the loading arm is supplied by the vehicle. There is a remote controller, so the loading arm can be connected or disconnected with vessel or site pipeline easily.
