Abstract A folding mechanism for the discharge spout sys- tem (12) of a pneumatic conveyor (10) is disclosed. The folding mechanism includes a hinge mechanism (55) having an axis (66) which is skewed with respect to a plane perpendicular to the alignment axis (26) of lower and upper tubes (20, 22). Such a hinge mechanism (55) allows the upper portion of upper tube (22) to pass the lower portion of lower tube (20) while upper tube (22) is pivot- ing from an operational configuration to a transit con- figuration. An hydraulic cylinder (68) powers the pivotal movement of upper tube (22). An over-center locking mech- anism (84) latches lower and upper tubes (20, 22) in the operational configuration.
