Structure
　　　1. The crane mainly consists of pedestal, slewing support, boom and operating stand.
　　　2. Pedestal is a column, which is to be connected to the deck with bolts.
　　　3. The slewing support and oil tank are Integrated with compact structure and small body, It is connected with the pedestal through middle slewing bearing.
　　　4. The boom is box-type structure , It is welded with steel plates, Its Inside does not need maintenance.
　　　5. The operating stand is welded beside the post, all action is to be done on the stand.
Features and performance
　　　1. The crane is featured with light weight, flexible operation and easy maintenance.
　　　2. The crane has fine performance of hoisting, slewing and luffing.
　　　3. Hoisting, slewing and luffing are to be fully hydraulic driven by a hydraulic motor.
　　　4. The electric motor is mounted at the bottom of pedestal.
　　　5. The hydraulic pump, which is connected to the electric motor through a coupling, is mounted on the slewing bearing
　　　6. Hoisting winch is mounted on the slewing bearing, it is driven by a piston type hydraulic motor and it will drive the drum to wind the steel wire to lift cargo with the help of planet gear box. The steel wire is galvanized with no twist.
　　　7. The slewing mechanism is mounted on slewing bearing, it is driven by a fine piston type hydraulic motor, crane slewing is to be achieved by means of direct engagement of internal teeth with the output pinion of planet gear box.
　　　8. Crane luffing is to be driven by a fine performed hydraulic cylinder, the limits of cylinder also have the function of safe buffering.

All the measures are indicative and can be tailored according to your requests.
