Electrohydraulic cargo crane of 80 t capacity

Crane of 80 t capacity

Deck-mounted, full-swing, jib hydraulic crane of 80 t capacity is a new generation crane that meets all up-to-date requirements.

It is designed for handling special and general cargoes and installed on ocean-going ships.

The crane features stepless speed control of all functional movements. All crane equipment is unitized and assembled in fully enclosed housing.

Twin-crane operation provides 160 t capacity.

The crane features high reliability.

At customer’s request, the supplier provides starting and adjusting works, personnel training and after-sale servicing of the crane during its whole service life.

The crane service life is 30 years, not less.

Cargo hoisting and slewing mechanisms – multistep planetary reduction gear driven by axial hydraulic motors. Disk brakes normally closed at the planetary reduction gear input are hydraulically released.

Luffing mechanism – hydraulic cylinders with pilot-controlled check valve.

Jib – steelwork of box-girder section welded of sheets.

Cabin – overhanging, enclosed with electric light. Access to the cabin – by exterior ladder.

Hydraulic system – working pressure up to 20 MPa; cooling and heating systems of working fluid; automatic warm-up system for the crane starting at low temperatures.

Power supply – power circuits 380 V, 50 Hz, lighting circuits 220 V, 50 Hz. Connection to ship’s mains – via a slip ring collector.

Twin-crane operation is controlled from the one (leading) crane. Independent operation of each of two cranes is also possible. In this case the cranes are controlled from their own cabins.
