en.Wedoany.com Reported - Manitowoc has introduced the Potain Power Solutions energy storage system series, designed to power tower cranes and reduce reliance on diesel generators or unstable power grids at construction sites.
Designed for the high-duty cycles and peak power demands of heavy lifting operations, the energy storage units are available in emerging markets across Asia-Pacific, the Middle East, India, Africa, and Latin America. The product line offers a range of power output options, including baseline configurations of 135 kVA and 270 kVA, as well as high-capacity models exceeding 375 kVA. Hardware integration covers the entire Potain tower crane product line, from entry-level models to large specialized cranes, while also providing auxiliary power for adjacent site equipment.
The system is engineered to handle high-rate discharge and sudden peak current surges during heavy load lifting, enabling tower cranes to maintain full-load lifting capacity and operating speed without localized voltage drops or power interruptions. The unit is equipped with grid stabilization software and an uninterruptible power supply (UPS) function, protecting sensitive crane electronics from mains interruptions, voltage sags, and unstable grid inputs.
The system utilizes a high-rate lithium iron phosphate (LFP) chemistry, integrated with a bidirectional power conversion system (PCS) featuring high-speed insulated-gate bipolar transistors (IGBTs). During high-load lifting sequences, the inverter can respond within milliseconds, providing supplementary active power to smooth the demand curve. During no-load or descent phases, the system charges via a low-capacity grid connection or a small auxiliary generator. To maintain battery chemical stability in high-temperature and high-humidity environments, Potain Power Solutions integrates liquid-cooled plates that circulate a glycol-water fluid between battery modules, stabilizing battery temperature and preventing thermal degradation during high C-rate discharge cycles under extreme environmental conditions. The physical frame is designed with forklift entry channels, capable of withstanding mechanical vibration, physical impact, and dynamic shocks during transport and on-site relocation.
The energy storage platform is compact, facilitating transport and redeployment between construction sites. The integrated intelligent energy management algorithm can reduce on-site fuel consumption by up to 70% compared to standard diesel generator configurations. When operating in pure electric mode, it can completely eliminate on-site diesel generators, enabling silent operation and zero on-site emissions to comply with urban environmental regulations.
