The QZ-type grab bridge crane is suitable for warehouses and workshops in metallurgy, cement, chemical industries, and other enterprises. It is used indoors or in fixed outdoor spans for handling bulk materials such as limestone, ore powder, slag, coke, coal, sand, and minerals.

The crane mainly consists of the bridge frame, crane traveling mechanism, trolley, grab bucket, and electrical system. Its operating temperature ranges from –20°C to +40°C. The lifting device is a four-rope grab bucket with a double-drum mechanism, featuring simple structure and reliable operation. The grab can open and close at any height. It performs best when handling materials with particle sizes under 100 mm, offering high productivity. For materials larger than 200 mm, a toothed grab bucket is recommended. When used outdoors, the crane must be equipped with weatherproofing devices.
