TECHNICAL DESCRIPTION:

For the needs of the investor S.A. harbor Stara voda, we designed, manufactured, installed, tested and put into operation electric column jib crane for marina. The maximum load capacity of the crane is 6,3 t, the maximum reach of the hook is 4,5 m and the lifting height is 8,4 m. The crane is mounted in the port of Stara voda in Kostrena. The crane is used to lift the vessel ashore next to the crane and to lower the vessel into the sea.

 

The crane is controlled from the floor via a radio remote control unit, and in case of emergency there is a cable control unit located in the engine room of the crane.

 

Given the conditions and frequency of operation of the crane is classified in II. operating class. All crane operating movements: lifting/lowering the load and rotating the console are electrically driven.

 

The steel construction of the crane consists of:

• column: on which there is a climber and a maintenance platform,
• console: on which the driving hoist is suspended.

 

The load-bearing column is attached to the concrete foundation of the crane by means of anchor bolts and nuts. The console and the column are interconnected by an axial bearing that allows the console to rotate. The angle of rotation of the console is unlimited, ie it is 360 degrees.

 

The lifting mechanism consists of an electric driving winch manufactured by "MISIA PARANCHI" Milan, Italy, type: XM316NS4H10A / 3A.

 

The electrical equipment of the crane consists of:

• electric motor of double worm gearbox of crane branch rotation drive,
• electric driving hoist for lifting loads,
• rotary switch,
• control cabinet,
• radio remote control unit and cable control unit,
• main switches, and
• power and control cables within the crane itself.

 

Along with the SKD-RM 6,3 t / 4,5 m marine jib crane, a cross spreader hanging on a hook was also delivered. Two polyester straps are hung on the cross spreader in four-points and are used to cover the hull of a ship rising or lowering into the sea. The load capacity of the cross spreader is equivalent to the load capacity of the crane itself.
