Slewing Crane

Marine deck crane have been approved for use in demanding marine applications and environments.

Marine deck crane are manufactured by modern hydraulic systems and a high strength design coupled with modern fabrication techniques, the controls of hydraulic deck crane are fully proportional for precise controlled motions.

Engineers will design specially according your requirements and the crane usage. 

Features and performance of hydraulic slewing crane

* Hydraulic slewing crane has the characteristics of light weight, flexible operation, convenient maintenance, etc.

* Crane action is carried out by three power systems: lifting, slewing and luffing.

Hoisting, slewing and luffing are to be fully hydraulic driven by hydraulic motor set.

* The electric motor and pumps are mounted at rotary base interior.

* Hoisting winch is mounted on the slewing bearing, the drum turn to wind the steel wire to lift cargo. The steel wire Is galvanized with no twist.

* The slewing mechanism Is mounted on slewing bearing, It Is driven by a fine hydraulic motor, crane slewing Is to be achieved by means of direct engagement of Internal teeth with the output pinion of planet gear box.

* Crane luffing is to be driven by a fine performed hydraulic cylinder, the limits of cylinder also have the function of safe buffering.

* All action Is to be completed by a multi-directional valve.

* On the side of console is fitted with a manual emergent pump which Is 

used for emergence release in case of power off.

* Oil tank Is fitted with level and temperature meter, etc.
