Multipurpose electrohydraulic ship crane "Universal"
Multipurpose electrohydraulic ship crane "Universal" is designed to fulfil conventional cargo-handling operations as well as to transfer cargoes between ships on the run by alongside method or to a stationary object (offshore drilling platform) over a distance up to 60 m at sea force up to 4.
The crane "Universal" is equipped with special devices monitoring ship motions at cargo transfer from a ship to a moored ship. In conditions of mutual vertical movements at sea force up to 4 this device provides impact-free transfer.
The crane is intended for installation on ships of various purposes including fishing, rescue, support ships, etc.
The crane "Universal" satisfies "The Rules on Hoisting Gears for Sea-going Ships" of the Russian Maritime Register of Shipping and "The Rules on Design and Safe Operation of Hoisting Gears for Naval Support Vessels".

Jib – enclosed box-girder section.
Cabin – enclosed, arranged on the crane’s side. The cabin has heating system, window wipers, control panel and control board indicating running parameters – duties and operation modes.
Hydraulic system – working pressure up to 16 MPa.
Power supply – power circuit 380 V, 50 Hz; lighting and signalling circuits 220 V, 50 Hz. Connection to the ship’s mains – through a slip ring collector. Current – a.c., 3-phase.
