Introduction
The QD type double girder crane consists of a box bridge frame, travel mechanism, trolley, and electrical equipment. The frame uses box main girders welded by automatic submerged arc welding for high strength and rigidity. The hoisting mechanism employs high-precision hardened-face reducers with overload limiter and double height-limit protection; travel mechanisms fit polyurethane, hydraulic, or spring buffers, and trolley power uses an I-beam cable system for safety. With standardized, serialized, and generalized parts, it is available in A5 medium and A6 heavy duty classes; with rain-proof equipment for outdoor use, and with grab or electromagnet for bulk material and special operations.The QD type double girder crane consists of a box bridge frame, travel mechanism, trolley, and electrical equipment.

Our Advantage
Twin box-girder structure gives high load capacity and rigidity for stable, reliable heavy lifting.
Overload limiter plus double height-limit protection guard against overload and over-travel.
Hardened-face reducers offer high efficiency, long life, smooth running, and low noise.
Compatible with hooks, grabs, electromagnets, and special spreaders for indoor and outdoor duties.
Standardized, serialized parts with strong interchangeability ease maintenance and spare-part supply.
