GANGWAY HAVING SELF-RAISING ASSEMBLY
A raising assembly for use with a gangway connected for rotation between a raised stowed position and a lowered deployed position. The raising assembly comprises at least one fluid actuated cylinder connected to the gangway. A raising actuator is operative to cause operation of the cylinder in a manner that rotates the gangway toward the stowed position while the raising actuator is continuously activated by an operator. A lowering actuator is operative to cause operation of the cylinder in a manner that rotates the gangway toward the deployed position due to gravitational forces while the lowering actuator is continuously activated by the operator. The raising assembly is configured to maintain the gangway at a current position between the stowed position and the deployed position if the operator does one of ceasing to activate the raising actuator while raising the gangway or ceasing to activate the lowering actuator while lowering the gangway.
