crane, in particular for montagezwecke in the engine room of a ship

摘要

A crane installation, in particular for use in rooms in which the floor-to- ceiling height is locally reduced by beams 5 supporting an overlying deck 4, comprises a carriage 7 travelling on rails 6 below the beams and a trolley 12 travelling on rails provided in the carriage in a direction perpendicular to the travelling direction of the carriage. The trolley is U-shaped in plan view with two parallel legs and a connecting cross member, and a jib 23 is supported in the trolley for pivoting on an axis perpendicular to the two legs of the trolley. A lifting means 27 is suspended in a cable depending from the free end of the jib. In the areas between the deck beams the jib can be pivoted above the level of the undersides of the beams whereby the increased floor-to-ceiling height can be utilized in these areas for lifting and lowering a load and transporting the load laterally.
