ELECTRIC CRANES Ӏ SECTOR SPOTLIGHT
in just two hours. The eco-friendly electric
drive also eliminates engine maintenance, adds Sany. The crane has a working width
of 7.5 metres to provide enhanced stability. The crane’s chain type flat track pads are designed to handle sandy, muddy and gravelly conditions, Sany says. The crane’s battery is from

has increased by 40 percent on this crane, says XCMG, claiming it feels more like driving a car than a crane.
The driver’s cab includes an air suspension seat, electric heating and cooling and a multi-functional steering wheel, plus a 12-inch LCD instrument panel and 10-inch central control display. The electric crane is quieter in both driving and operation and can work continually for two shifts under pure electric operation, says XCMG. Charging duration (SOC 30-80 percent) takes just 30 minutes and it can be fast charged using a high voltage connection. A 96.2kWh smart charging unit can be specified. The crane has a waterproof rating of IP68. A video of the crane can be

Sany, had a new large electric crawler crane on its stand: the 200-tonne capacity SCC2000A-EV. It is the first model in Europe and has been sold to Nederweert, Netherlands-based crane and transportation company Herpertz by Sany’s dealer for Europe, Netherlands-based company

main boom, a 30 metre fixed jib, a 63 metre luffing jib, and a maximum lifting moment of over 1300 tonne metres. It is powered by a 422.87kWh high-capacity battery and a motor with a rated power of 234kW, a rated torque of 1118 tonne metres, and a peak torque of 2125 tonne metres. This, Sany claims, offers powerful performance and a run- time exceeding eight hours. It supports AC/DC multi-mode
charging with real time monitoring and protection against overheating, overcurrent and leakage. It also enables European
standard double-gun DC fast charging and can be fully charged
Danfoss supplied
a eHydraulic Power Module for Sany’s SCC2000A-EV
CATL. The hydraulic motor and reducers are from Rexroth. And the electric motor and main valve are from Danfoss. Danfoss Power Solutions’ Editron division delivered its first eHydraulic Power Module for the crane. The eHydraulic system integrates a Danfoss Editron synchronous reluctance assisted permanent magnet motor with a Danfoss variable displacement axial piston pump to maximise performance and efficiency. Comprising an Editron
PMI375-T1100 motor and D1P 260-cc pump, the system is optimised to deliver peak performance and maximise hydraulic system efficiency, says Danfoss, extending machine runtime on a single charge. The full hydraulics system also includes a Danfoss Series 90 pump and PVG 128 valve.
