What is a Bottom Loading Arm?
Bottom loading arm is a specialized transfer equipment designed for loading and unloading liquid materials (such as chemicals, petroleum products, and solvents) through the bottom of tank trucks or railcars. Unlike top loading arms that connect to the top of the tank, it docks with the dedicated bottom outlet of the transport vehicle, forming a closed transfer system.
It is widely used in industries requiring high safety and environmental protection standards, as its bottom-docking design minimizes material volatilization and spillage. The core structure includes a rigid arm assembly, rotary joints for flexible adjustment, a sealing flange for tight connection, and safety devices to ensure stable and safe material transfer.
