On 8 November, the 100 t double girder gantry crane built by Henan Mine Crane for a China Nuclear Power project passed factory acceptance. During acceptance the project team ran high-precision tests including loaded travel and positioning, all of which met the criteria and won unanimous customer approval. To date the company has built more than 100 high-precision, anti-sway, high-quality cranes for the project.

Servo control for precise positioning — servo control of long and cross travel gives a minimum inching distance of 0.5 mm. Smooth hoisting with precise anti-sway — vector-controlled VFD hoisting with PLC anti-sway achieves positioning accuracy within 5 mm. Modular design and refined structure — high standardisation improves parts utilisation. Double braking for safety — dual brakes on the hoisting mechanism hold rated load without slip and provide a high safety factor.

Passing factory acceptance marks another innovation achievement for Henan Mine Crane in China's nuclear power sector. The two sides will use this as an opportunity to strengthen cooperation in technology R&D and premium manufacturing, contributing to high-quality development of the country's nuclear power industry.
