The material dredged, sand and mud, IS conveyed in the barges to the discharge 1031 stage, near the centre of the station, and lifted to a height of 21 ft. above high-water ordinary spring tides. The hoisting macliinery is worked by shafting, driven by a 12 horse-power portable engine. The shafting drives two sets of gearing, working each two grooved winding drums, 16 in. in diameter, with |-in. chains coiling in contrary y 5 y IfTf^, directions, so that whilst one jib is lifting the other is lowering. The skips hold 22^ cub. ft. of material, weighing 1700 lb., and discharge their contents into tip waggons working upon a platform immediately below. The weight of the empty skip is 485 lb., making a total weight of 2185 lb. o t- j
