Electrohydraulic ship cargo cranes of 8 t capacity
Full-swing, hydraulic, deck-mounted jib cranes КЭГ-8018 are developed on the basis of the crane C-818 model manufactured under license of AB Hägglunds company, Sweden.
Cranes feature high reliability, stepless speed control of all functional movements. All the crane machinery is unitized in the totally enclosed housing.
Cranes are intended for installation aboard ocean-going ships for handling general cargoes.
At customer’s request, the supplier provides starting-and-adjusting works and after-sale servicing during the crane whole service life.
The crane service life is not less than 25 years.

Hoisting, luffing and slewing machinery – gearless, driven by low-speed high-torque hydraulic motors. Band brakes – short-circuited, hydraulically released.
Jib – totally enclosed box-girder section.
Cabin – enclosed, with electric lighting. Access to cabin – by means of exterior ladder.
Hydraulic system – working pressure up to 17.5 MPa; cooling and heating system of working fluid; automatic warm-up system to keep the crane in readiness for starting at low ambient temperatures.
Power supply – power circuits 380 V, 50 Hz; lighting circuits 220 V, 50 Hz. Connection to the ship’s mains – via slip ring collector.
