Hydraulic Telescopic Boom Marine Crane

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. 

WELDING

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.

Steel Structure

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

SLEWING MECHANISM

The crane is provided with a slewing ring designed for marine applications. The gearing is internal. The slewing gear is of the planetary type with multi disk brake, adjustment of backlash betweenpinion, slewing motor is gerotor motor.

Safety system

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.
