Similar to those operatingat the Bute docks, threeor more cranes can beworked simultaneouslyinto one vessel (Fig. 69),and as much as 330tons have been shippedby one crane in an hour,and 6,715 tons have beenshipped into a vessel in11 hours, or an averageof 610 tons per hour.Many trunk and turretsteamers load full cargoesof coal by such craneswithout any manual aidwhatever. Shippers alsoattach so much import-ance to them that theyfrequently elect to waitfor a crane berth ratherthan have their coalshipped from the usualstaithe.

The central latticetower, A (Figs. 70 and 71), carries a revolving head, B, to whichis suspended a pair of steel lattice girders, CCl, curved at theirlower ends, carrying two endless chains of buckets travellingupon flanged rollers, these being driven by a steel-wire rope fromthe pair of winding-engines, as shown. These engines are alsoused for raising and lowering the girders as well as turning themthrough a quadrant, in order that they may be stowed away foreand aft, as shown in Figs. 70 and 71. Clutches are arranged tothrow an} of the three sets of gearing in or out as required for thepurposes mentioned, and hand-crabs enable the ends of theelevator girders to be adjusted at pleasure to suit the coal orgrain in the barge, and the height of the steamer or quay.
