HiTe calls on Saft's on-site service for optimized operation of innovative hybrid-powered RTG crane in China

Saft's on-site installation, commissioning and training service has ensured the successful implementation of the hybrid diesel generator and Li-ion battery power system for a new generation Rubber Tyred Gentry (RTG) crane in China.

Shanghai Hi-Tech Control System Co Ltd (HiTe), a Chinese system integrator, was engaged by Rainbow Cargotec to develop a new hybrid power system for its innovative new generation of RTGs designed to help port and terminal operators reduce carbon emissions and eut fuel costs.

To ensure the success of the prototype unit, HiTe called on additional support from Saft's service team for installation, commissioning and training.

Optimizing battery system operation in a demanding regenerative braking application

As air pollution continues to be a major issue in China, HiTE has developed a hybrid power system that utilizes a smaller than usual diesel genset operating in combination with a Saft Li-ion battery. This approach significantly reduces the genset run time to eut bath emissions and fuel costs.

For Rainbow Cargotec, HiTe developed a hybrid power system capable of hoisting up to 15 fully loaded TEUs (Twenty Foot Equivalent containers) of 41 tons in conti­nuous operation. The ESSU (Energy Storage System Unit) is based on Saft's SLFP™ (Super Li-ion Iron Phosphate) tech­nology, with 22 SLFP™ modules capable of delivering continuous current of 500 Amps with an energy storage capacity of 57 kWh. The use of regenerative braking requires the ESSU to handle very large, short dura­tian currents - 220 kW for 5 seconds.

Key features

• Specialist battery technicians on site for 11 days in total
• Installation included inspection, charge and discharge testing and capacity testing in compliance with regulations
• Training delivered on site by field-experienced trainers
• Mix of theoretical and hands-on training
• Contributes to a long service life estimated at 5 years

Key benefits

• Saft support ensured smooth operation of the hybrid system from day one
• Saft service has minimized operational risk of introducing innovative battery systems
• Saft has helped HiTe"s operators to become comfortable with operation of Li-ion batteries

The result - delivery of a successful prototype

Following the construction of the prototype RTG, Rainbow Cargotec submitted the unit ta a stringent programme of testing and evaluation. Ultimately, Saffs service ensured that the hybrid power system met its performance specifications and contributed ta the success of the prototype.

Service ensures reliable through-life performance

Saft mobilised quickly and sent qualified technicians ta HiTe's facility in Shanghai. During their time on site, Saffs technicians qualified HiTe's operation and set up a performance index for the batteries. This ensured that HiTe's manufacture of hybrid systems will be bath high quality and repeatable.
HiTe's team also benefit from a dedicated portal ta manage after-sales daims. This ensures rapid and customized responses ta enquiries around the dock.
