INVESTOR: Hripa Ltd.
LOCATION: Kali
YEAR OF PRODUCTION: 2015.
TECHNICAL CHARACTERISTICS:
- maximum crane capacity: 6,3 t
- hook reach: 4,5 m
- lifting height: 7 m
- load lifting speed: 4/1,3 m/min
- console rotation speed: 0,09/0,285 rpm

TECHNICAL DESCRIPTION:
According to the request of the investor, company Hripa 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 hook reach of 4,5 m and a lifting height of 7 m. The crane was installed on the operating shore of company Hripa Ltd., and is equipped with a cross spreader for boats.
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 on the control platform on the crane is installed.
The steel construction of the marina crane basically consists of:
- load-bearing column,
- console.
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,
- main switches, and
- power and control cables within the crane itself.
Along with the SKD-RM 6,3 t / 4,5 m marine crane, a cross spreader hanging on a hook was also delivered. Two polyester straps are hung on four-points on the cross spreader and are used to cover the hull of a ship rising or lowering into the sea. The load capacity of the cross spreader should be equivalent to the load capacity of the crane itself.
