Abstract
A gangway comprises a fixed platform and 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. A raising assembly is operative to rotate the support structure from the deployed position to the stowed position. The raising assembly includes at least one fluid actuated cylinder connected between the fixed platform and a distal end of the support structure. A raising actuator is usable by an operator to cause operation of the cylinder in a manner that rotates the support structure toward the stowed position.

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.
