| Specifications | : | Offshore Lattice Boom Crane for sale Offshore Lattice Boom Crane - 70 ton New Offshore Crane for Sale Brand new 70T lattice boom offshore crane with ABS class certificate and API 2C monogram General Specification Slewing Angle : 360º(Continus) Slewing Speed(Full Load) : 0~0.85rpm Luffing Time(Full Load) : 180s Up/down Luffing Angle : +15° ~ +82° Parking Angle : -5° ~ +15° Operator Cabin :Left Side Main Winch Data Lifting Capacity(SWL) : 100T@21m,40T@45m,See Loading Chart; No. Of Fall : 4 Working Radius : 10.0m(Min) / 45m(Max) Main Lifting Speed(0-125T) : 18m/min Hook Travel : 95m Aux Winch Data Lifting Capacity(SWL) : 20T@48m, Man Riding :1.5T No. Of Fall : 1 Working Radius : 11.0m(Min) / 48m(Max) Main Lifting Speed(Full Loading) : 0~67m/min Lifting Height : 100m Note : All operational speeds stated above are based on average volumetric efficiencies provided by our suppliers of hydraulic components. 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.
