PROJECT NAME: Marina crane SKD-RM 6,3 t / 4,5 m

 

INVESTOR: Luka Volme Ltd.

 

LOCATION: Medulin

 

YEAR OF PRODUCTION: 2019.

 

TECHNICAL CHARACTERISTICS:

• maximum crane capacity: 6,3 t
• hook reach: 4,5 m
• lifting height: 7,2 m
• load lifting speed: 4/1,3 m/min
• console rotation speed: 0,09/0,285 rpm
• rotation angle: unlimited

 

TECHNICAL DESCRIPTION:

According to the request of the investor, company Luka Volme Ltd., we designed, manufactured, assembled, tested and put into operation an electric column jib crane for marina with a load capacity of 6,3 t, a reach reach of 4,5 m and a lifting height of 7,2 m. The crane is installed on the operating shore of company Luka Volme Ltd. for the purpose of lifting / lowering the vessel from / into the sea, and is equipped with a cross spreader.

 

Given the conditions and frequency of operation, the crane is classified in II. operating class. The lifting / lowering of the load as well as the rotation of the console are electrically driven.

 

The angle of rotation of the console is unlimited, while the crane has a fixed hook reach. The crane is controlled remotely via radio control unit, and as a reserve, the cable control unit which is conected the control cabinet on the crane is installed.

 

The steel construction of the jib crane basically consists of:

• load-bearing column,
• console and
• service platforms with climbers.

 

The lifting mechanism consists of an electric hoist manufactured by "MISIA PARANCHI S.R.L." Milan, Italy, type: XM316NS4H7A/5 and a set of turn pulleys on top of the support rope guide, and a hook assembly with a load capacity of 6,3 t.

 

The electrical equipment of the crane consists of:

• planetary gear motor, for crane console rotation drive,
• electric hoist for lifting loads,
• rotary switch,
• control cabinet,
• radio remote control unit and cable control unit (spare),
• main switches, and
• power and control cables within the crane itself.

 

With a column jib crane for marinas for the company Luka Volme Ltd. we designed and manufactured a cross spreader that is used for raising / lowering boats from / into the sea. Two polyester straps are hung on four-point on cross spreader and they 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.
