The article describes/ship-mounted cranes produced by five major manufacturers. Stothert and Pitt, Bath, offer a whole range of deck machinery, including fixed and twin level-luffing deck cranes. The fixed electro-hydraulic cranes are rated at capacities between 5 and 25 t, with a maximum radius of 22 m. The twin cranes, mounted on a common slewing table, have capacities from 2 + 12.5 to 2 x 25 t. Designs for larger capacity deck cranes can be made to suit individual requirements. Hagglung and Soner, Sweden, absorbed the electric deck crane manufacturer ASEA and the gantry crane maker Munck in 1972, thus enable them to supply a wider range of shipboard cargo-handling equipment. Their cranes have now attained 40 t capacity and 30 m outreach. Sited either individual or twinned on common platform they incorporate Ward Leonard control of all three motions, giving fine speed regulation. Liebherr manufacture a series of single and twin deck cranes with lifting capacities ranging from 3 to 100 t. The company also builds gantry cranes for Ro/Ro ships, supply vessels, and oil production platforms. The latest crane produced is the MP crane for unit load handling, which has a lifting capacity of up to 80 t. Blohm and Voss started producing deck cranes in 1975 with the takeover of the Kampnagel Cranes company. Demag-Kampnagel is now a B and V trade mark. For use mainly on bulk carriers these cranes can be fitted with a four-rope grab, handling 20 to 25 t of general cargo at 10 m radius. In a twin mode, the two cranes have a maximum combined capacity of around 50 t. An unusual feature is the mounting, the crane itself being first mounted on a movable revolving carriage, which is then positioned on top of a rail-mounted portal, spanning the width of the ship and able to move along its length. Speedcranes, of Gourock, specialise in the design and manufacture of fast cargo-handling equipment. The company has secured its first orders for heavy-lift derricks of 100 t SWL. The company has 62 cranes on its order book, well overhalf of which are destined for overseas markets. The Speedcranes special design of derrick crane can lift light loads at winch speed and then change to lifting heavy loads on mutlipurchase without re-rigging and in under four minutes. Order from: BSRA as No. 46,774.
