PROJECT NAME: Marina crane SKD-RM 15 t / 5,5 m

 

INVESTOR: Sailing club Orsan

 

LOCATION: Dubrovnik

 

YEAR OF PRODUCTION: 2006.

 

TECHNICAL CHARACTERISTICS:

  • maximum crane capacity: 15 t
  • hook reach: 5,5 m
  • lifting height: 9 m
  • load lifting speed: 4/1 m/min
  • console rotation speed: 0,3 1/min
  • console rotation angle: unlimited

 

TECHNICAL DESCRIPTION:

According to the request of the investor, sailing club Orsan, we designed, manufactured, assembled, tested and put into operation an electric column jib crane for marina with a load capacity of 15 t, reach of a console 5,5 m and a lifting height of 9 m. The crane is installed on the operational shore of the sailing club Orsan, for the purpose of lifting / lowering the vessels from / into the sea and is equipped with a cross spreader.

 

Due to the conditions and frequency of operation the crane is classified in the I. 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 via a remote radio control unit, and as a backup, a cable control unit is installed in control cabinet on the service platform.

 

The steel construction of the jib crane basically consists of:

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

 

As a lifting mechanism, we installed an electric hoist manufactured by "MISIA PARANCHI S.R.L." Milan, Italy, type: ME 160 SR4 TNA / 5-D-4, which is mounted in standing position, and it is bolted to the base inside the engine room.

 

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,
  • main switches, and
  • power and control cables within the crane itself.

 

In addition to the SKD-RM 15 t / 5,5 m jib column crane, a hook-mounted cross spreader was also supplied. 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.
