  hydraulic cylinder and (2) two swing winches are mounted on the trunnion (or gimble) end of the ladder.
  The ladder is connected to the hull with a gimble arrangement to allow the ladder to swing independent of the
  dredge in swinging ladder mode.
  There is a suction hose between the ladder and the dredge center hull to transport the slurry to the suction side
  of the dredge pump. The ladder is raised and lowered by a single double acting hydraulic cylinder.
  Rod end is mounted to the gimble end of the ladder with the blind end attached to the fwd end of the center hull
  section. The ladder depth gage is of the mechanical type and is located on the aft (gimble) end of the ladder in

  The aft spud is a kicker, or walking spud. With the aft spud in the full down position, a single double acting
  hydraulic cylinder pushes the spud aft to advance the dredge for the next cut or to walk the dredge to another
  digging position.
  The fwd spuds are only used in the swinging ladder mode, when digging conventional, these spuds are pinned up
  high or removed.
