Yuntian Heavy Duty European Type Single Girder Overhead Crane

The Yuntian HD (Heavy Duty) European Type Single Girder Overhead Crane is the high-performance variant within Yuntian's European single girder crane range. While the standard European single girder is engineered for everyday light-to-medium lifting tasks, the HD series is purpose-built for facilities that demand higher work intensity, longer continuous operation, and greater structural reliability.The HD designation signals three principal upgrades over the standard model. First, the main girder is fabricated from Q345B high-strength structural steel with an optimised box-section profile, computer-analysed for rigidity, delivering superior bending and torsional resistance under frequent loading cycles. Second, all drive units are three-in-one geared motors sourced from European brands (SEW, ABM, or equivalent), featuring hard-tooth surface gearing, variable frequency drive (VFD) as standard, and disc-type electromagnetic brakes. Third, the crane's base work duty rating starts at A5 (ISO) and can be extended to A7 for heavy-duty applications—making the HD series suitable for continuous multi-shift operations that would exceed the design limits of a standard single girder crane.
