Abstract
A downsend terminal for a pneumatic transport tube system has a pivoting tube section pivoting about an upper horizontal axis to move the pivoting tube section between a first vertical position and a second oblique position. When at the oblique second position, the carrier is dropped out of the pivoting tube section onto a carrier support holding the carrier in a generally vertical position for access to the user. When the user completes the transaction, the terminal pulls the carrier vertically back into the pivoting tube section. If the carrier is overloaded, there is insufficient force to lift it off of the carrier support, and therefore an overloaded carrier is prohibited from entering the transport tube system. In addition, the construction prevents debris and other material from entering the transport tube system.
