1. A gangway comprising:
a fixed platform;
a support structure connected to the fixed platform in a manner that allows the support structure to rotate with respect to the fixed platform between a raised stowed position and a lowered deployed position; and
a raising assembly operative to rotate the support structure from the deployed position to the stowed position, said raising assembly including:
first and second fluid actuated cylinders respectively situated on left and right sides of the support structure, the cylinders being connected between the fixed platform and a distal end of the support structure and retractable to rotate the support structure toward the stowed position;
a raising actuator usable by an operator to cause operation of the cylinders in a manner that rotates the support structure toward the stowed position, the raising actuator including a raising valve; and
a hydraulic pump driven by a motor.
