This type of 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.
