Note
All operational speeds stated above are based on average volumetric

A speed variation tolerance of +10% to -5% is within the accepted range
and should be taken into consideration.
Hydraulic Arrangement
Hydraulic Systems
The hydraulic transmission will be designed for optimum performance
within the constraint of available horsepower. High pressure hydraulic
system uses power more efficiently and applies power as needed.
All motions controls offer infinitely variable speed and full reversing
characteristics. Two full flow filters will be installed. The filter(s) will
be adequately sized for full flow operation without causing pump
cavitation. Replaceable wire mesh filter cartridge of minimum
absolute value of 40 micron will be used. The pumps will have
overflow suction independent of the reservoir, and the arrangement
of piping can avoid air pockets.
Hoisting Circuit
Each winch is driven by a common open loop hydraulic system
including piston pump, piston motor and epicycles gearbox. Each
winch is fitted with oil immersed, multi-disc and dynamically rated
“fail safe” brake.
The fixed displacement hoist motors offer a constant operating speed.
Slewing Circuit
The slew circuit is driven by a common open loop hydraulic system.
Dynamic braking of slewing is by means of hydrostatic compensation.
Similarly positive locking brakes are fitted in the circuit and used as
static brake;
Luffing Circuit
Luff circuit is driven by a common open loop hydraulic system. Each
winch is fitted with oil immersed, multi-disc,dynamically rated “fail safe”
brake. an additional luff ratchet cylinder is included, providing a positive
means of locking the luff drum whenever the prime mover is shutdown.
Hydraulic Piping
1. Pipes: No pipe threads will be used for the high-pressure lines larger
than 3/8". Hydraulic components that have pipe threaded ports lines will
have a minimum working pressure 300PS.
2. Pipe fittings: Zinc plated mild steel material. External fittings are
painted and protected by Denso tape or equivalent against corrosion.
3. Hoses: High rubber quality for best resistance against sunlight and
salinity, Wire breaded for applicable specified hydraulic pressure ratings
4. Hose couplings: Zinc plated mild steel material, External couplings
are painted and protected by Denso tape or equivalent against corrosion
Hydraulic Oil Tank
1. Level gauge with isolating valve (to top cover)
2. Inspection and cleaning cover
3. Filter with fine mesh stainless steel strainer and ventilation
4. A relief valve will be installed in the discharge line of pump.
Cooling Circuit
The air-oil heat exchanger will be provided and sized to ensure
continuous operation of the crane under the ambient temperatures
given on the data sheets.
Electric Arrangement
Standards, Codes and Protection
Refer to Codes Of Practice and Standards. The electrical systems
onboard the crane complies with these standards for good offshore
electrical design and engineering practices.

Others
Junction box(es) is provided at the pedestal interface for connection
to client supply.
By default only SS316 junction boxes are installed onboard.
Generally cable wires will be multi-stranded copper and protected
against mechanical damage. All power and control cables are with
XLPE/EVA/GSWB/EVA construction. Occasionally able of
XLPE/EVA/CWB/EVA is used when big power cable is part of
the design. All electrical lines are tagged accordingly for ease of
maintenance.
