Danfoss Power Solutions’ Editron division has delivered its first eHydraulic Power Module to SANY for use in a newly electrified 200-tonne lattice-boom crawler crane. The system, which integrates a synchronous reluctance-assisted permanent magnet motor with a variable displacement axial piston pump, optimizes hydraulic performance and efficiency.
SANY introduced the fully electric, battery-powered crawler crane earlier this year as part of its broader effort to reduce emissions from heavy construction equipment. Construction machinery is estimated to emit approximately 400 million tonnes of carbon dioxide annually, according to IDTechEx, making electrification a key strategy for sustainability.
SANY has previously electrified several lower-capacity crawler crane models and is expanding electrification efforts to larger platforms. For its 200-tonne model, SANY selected the Danfoss integrated eHydraulic Power Module to power both the machine’s traction and work functions.
The system includes the Editron PMI375-T1100 motor and a D1P 260-cc pump, engineered for peak power output and extended runtime per charge. The hydraulic configuration is further supported by a Danfoss Series 90 pump and PVG 128 valve.
By supplying the electric motor and hydraulic pump as a pre-integrated unit, Danfoss reduces installation complexity and minimizes the risk of performance issues such as noise and vibration—challenges that can arise when using flexible couplings. The compact design and CE certification, along with Danfoss’ global support network, were cited as additional reasons behind SANY’s choice.
“Building a solution for SANY’s high-capacity platform with the Danfoss integrated eHydraulic Power Module marks a milestone,” said Roy Chen, president of the Editron division at Danfoss Power Solutions. “eHydraulics represents the future. Together with our Controls division, we have designed a system combining our D1P pump and Editron motor while tuning control algorithms to maximize efficiency.”
“Conventional hydraulics still plays a role in the electrification of heavy machinery, particularly machines of this size,” said Henrik Jørgensen, president of the Controls division at Danfoss Power Solutions. “By integrating Danfoss’ advanced hydraulic solutions and electrification technology, we are empowering a smooth transition to more sustainable operations.”
