The hydraulic union body, identified by part number 621 011 40, serves as a connection point within the fluid power circuits of the Demag AC80-1 crane. This component acts as an interface between hydraulic lines or system assemblies, providing a secure path for fluid circulation throughout the machine. It is engineered to maintain the integrity of the hydraulic network, supporting the distribution of pressure and flow required for various crane operations, including steering and boom actuation systems.
This specific union body is compatible with the Demag AC80-1 model. It is designed to meet the technical requirements of the hydraulic system, ensuring proper fitment and alignment within the existing plumbing. The component is manufactured to facilitate a tight seal, which is necessary for the containment of hydraulic fluid under operational pressure.
In hydraulic systems, union bodies function as essential connection points that allow for the modular assembly and maintenance of fluid lines. By securely joining segments of piping or hose, these components enable the pressurized fluid to travel from the pump to the actuators without leakage, maintaining the overall efficiency of the machine's hydraulic circuits.
