摘要： 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 self-raising assembly is operative to rotate the support structure from the deployed position to the stowed position. The self-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.

摘要： A spiral staircase comprises a mounting column extending along a longitudinal axis. A plurality of tread assemblies each having a tread portion attached to a mounting plate is also provided. The tread assemblies are axially and angularly offset from an adjacent tread assemblies along the mounting column. In this aspect, each mounting plate has a first face that engages a corresponding portion of an outer surface of the mounting column and a second face from which the tread portion extends. Each of the tread assemblies further have attachment hardware that secures the mounting plate to the mounting column. Prior to attachment to the mounting column and in an unstressed state, the mounting plate has a first radius of curvature and the corresponding portion of the outer surface of the mounting column has a second radius of curvature. The first radius of curvature is less than the second radius of curvature so that when the mounting plate is secured to the column with the attachment hardware and the second face of the mounting plate substantially engages the mounting column, the mounting plate is in an elastically deformed state applying tension to the attachment hardware to inhibit loosening thereof.

摘要： A gangway comprises a fixed platform and a support structure. The support structure is connected to the fixed platform in a manner that allows the support structure to rotate with respect to the fixed platform. A releasable position locking assembly inhibits rotation of the support structure in a raising direction.
