Liquefied Gas Filling鹤管 / Cylindrical Filling鹤管

The鹤管, also known as a liquid loading and unloading arm, consists of rotating joints, inner arm, outer arm, vertical pipe (for land use), three-dimensional joints (for marine use), balancers, control systems, and other components. It is primarily used as loading and unloading equipment for liquid media in tanker trucks, rail tanker cars, or tank ships.
Features of the crane pipe:
1. Compared to the traditional flexible hose connections, the鹤pipe utilizes a rigid connection method, coupled with safety features like emergency disengagement, effectively preventing pipeline bursts and fractures, offering a high degree of reliability.
2. The swivel joint is crafted using superior double-roller technology, offers easy 360-degree rotation, is leak-proof, and is convenient for maintenance and upkeep.
3. The flexible, balanced spring cylinder balancer ensures easy and effortless operation of the loading and unloading arm, allowing a single person to connect pipes to tank trucks and effortlessly control the loading and unloading process.
4. Custom-sized according to the client's loading/unloading scope requirements; during the process, it moves in sync with the tanker truck within the normal range of its movement.
5. Pipelines are made of materials such as carbon steel, stainless steel, and aluminum alloy, depending on the type of liquid medium, ensuring long service life.
6. Pipelines can be lined with Teflon and equipped with heating devices, enabling the transportation of various liquid mediums such as hydrochloric acid and asphalt.
7. Utilizing enclosed loading and unloading procedures can minimize the volatilization of the medium, reducing environmental pollution.

Principle of鹤管 installation:
1. Necessary safety precautions should be taken during installation to prevent accidents and ensure the safety of personnel and equipment.
2. The connection between the pier and the crane pipe should be equipped with a standard flange corresponding to the crane pipe, with the flange approximately 3.7 to 4.0 meters from the track surface.
3. During assembly, refer to the work drawing and install from the base rotator to the vertical aluminum tube, from bottom to top, and then install the balancer.
4. When installing the balancer, first raise the oil feed arm to about 60°, install the pins on both sides of the balancer onto the hooks, then align the single ears of the lifting and rotating lever on one end of the balancer with the housing, install the pins, and finally, install the open pins.
5. When adjusting the balancing force, place the oil pump in a horizontal position, unscrew the end cover of the balancer, and you will see the adjustment screw. If the crane pipe has a tendency to descend freely, tighten the screw with a socket wrench. If the crane pipe has a tendency to rise, loosen the screw until the oil arm stabilizes within the range of approximately -5° to 60°.
