SWING MACHINERY

Slewing is provided by Planetary gearbox with hydraulic motor.

Having 0-10 rpm slewing speed.

360° slewing is supplied.

Foundation is to be bolted.

 

UnderCarriage With side Pontoon and Spud Leg

Pontoon : Watertight type and Axial piston drive system. Have inspection menhole.

Ever Pontoon have Triple stands track chain.Roller type.

Design criteria is to be Protect from outerside material .

Track shoes made by High density Polyethylene material.

Material will be used Hardox 400.

Crossbeam spud leg is to be mounted on pontoon.

ACR ( Atmospheric Corrosion Resistant ) Steel plate will be used.

 

CRANE CONTROL

The crane is manufactured according to SOLAS and IMO regulations.

The crane is operated via hydraulic valves with proportional control (levers). Hydraulic control valves will be delivered as loose as to be placed a seperate column near the crane.

Pressure indicator, oil level indicator, emergency stop button and HPU start/stop buttons will be placed on the Hydraulic power unit..

 

Operator Cabin :

All steel fabricated with acoustical lining and tinted safety glass throughout. Deluxe seat incorporates armrest-mounted electric dual – axis controllers. Dash panel incorporates gauges for all engine functions.

Outrigger detector

Boom load holding valve system

Over hoist prevent system

Automatic brake all planetary system

Slewing lock

Hydraulic oil temp warning

 

LOAD LIMITING SYSTEM

Each hydraulic circuit is provided with equipment for limiting hydraulic pressure to present values corresponding to the crane capacity.

 

SAFETY SYSTEMS

-Emergency stop,

-Overload protection of all motions by overload relief valves,

-Hydraulic hook stop in upper position,

-Load holding valve on the hydraulic luffing cylinder,

-Overload protection, all motions will be protected against overload by individual safety valves,

-Low oil level will be indicated visually on the oil level gauge on the HPP. When oil level to be low, electric motor will stop automaticly.

 

 

HYDRAULIC CYLINDERS, PIPES AND HOSES

Cylinders are double acting type and cylindertube is produced according to DIN 2391 standart. All hoses and fittings suitable for system working pressure and flow rate.

Hydraulic cyclinders 200 microns chrom plated.

 

STEEL STRUCTURE

The steel quality is selected in accordance with the classification societies recommendation to obtain necessary ductility for the lower temperature design limit.

All important weldings are carried out in accordance with welding procedure.

After welding a certain amount of NDT control is carried out. Boom meterial is high Strength Steel (Yield Stress 400-700-900 N/mm2) and boom section is hegzagonal. Foundation is designed according to max. load.
