The crane is controlled from an open platform above the slewing ring. One motions each (hoisting ,slewing or luffing) can be done with full load.Each hydraulic circuit is provided with equipment for limiting hydraulic pressure to preset values corresponding with crane capacity. The crane is provided with an automatic hook stop in top position.Over load safety device.Luffing up- down. The luffing cylinder is designed for safe buffering in extreme positions.

The drawing of the crane:
American Welding Society,all important welds are carried out in accordance with welding procedures. After welding, a certain amount of NDT control is carried out.
The steel quality is selected in accordance with ABS to obtain necessary ductility for the lower temperature design limits.Steel structure:pedestal,slewing device,straight arm
The safety devices are strongly constructed and approved for mainly lifting application. Big importance has been placed on the provision of adequate safety features throughout the design of the crane structure and its associated system.
