The Intelligent Grab Double-Girder Bridge Crane (QZ Type) is a high-performance overhead lifting solution manufactured by Henan Mine, engineered for fully automated, high-efficiency handling of bulk materials such as coal, ore, scrap metal, grain, and waste in demanding industrial environments . This crane features a robust double-box-girder bridge structure with a specialized four-rope grab mechanism, integrated with advanced intelligent technologies including PLC control, touchscreen interface, variable frequency drives (VVFD), anti-sway control, auto-positioning, and real-time safety monitoring systems . Operating under heavy-duty class A6 to A8 for continuous 24/7 operation, the crane supports manual, semi-automatic, and fully automatic modes with lifting capacities from 5 to 60 tons (grab capacity included), spans from 10.5 to 31.5 meters, lifting heights from 3 to 28 meters, and grab volumes from 0.75 to 10 cubic meters

The QZ type grab bridge crane uses a four-rope grab as a dedicated lifting gear to handle bulk materials such as ores, lime, raw coal, sand, coke, cement, and slag. This vehicle model features mature and reliable technology, flexible configuration, fast working speed, high efficiency, and good scalability. It is suitable for use in warehouses, material yards, workshops and other places.

Core Applications – Intelligent Grab Double-Girder Bridge Crane
1.Ports & Bulk Terminals – Automatically loads and unloads coal, ore, grain, and sand from vessels and rail cars, with real-time dynamic weighing (≤±1% accuracy) and anti-sway control for high-speed, precise cargo transfer .
2.Steel Mills & Scrap Recycling Yards – Handles ferrous scrap metal, slag, limestone, and coke for furnace charging, with intelligent grab control and multi-crane synchronization for high-volume, continuous scrap processing .
3.Power Plants – Unloads coal from trains or barges and transfers to stockpiles or boiler feeders, featuring laser height measurement, collision protection, and automated stacking to maintain consistent fuel supply .
4.Waste-to-Energy & Recycling Centers – Transports municipal solid waste, construction debris, and recycled materials to incinerators or sorting lines, with electro-hydraulic grab providing strong grip force for irregular loads .
5.Mines & Quarries – Handles extracted ore, gravel, and minerals from extraction points to processing areas or loading stations, with heavy-duty A7-A8 classification and weatherproof design for harsh outdoor conditions .
6.Cement Plants & Foundries – Transfers crushed limestone, clay, gypsum, and clinker to storage silos or mixer hoppers, with PLC-controlled grab cycles and remote fault diagnosis for reduced downtime .
