PRODUCT INTRODUCTION
The Double Girder Grab Gantry Crane is a heavy-duty material handling solution specifically designed for bulk and loose material operations in outdoor or semi-outdoor environments. Unlike standard hook-type gantry cranes, this crane is equipped with a motor-driven grab bucket (clamshell or orange-peel type) that opens and closes to scoop, transport, and discharge bulk cargo such as coal, ore, sand, slag, scrap metal, or grain. The double girder configuration provides superior rigidity, higher lifting heights, and greater stability compared to single girder designs, making it ideal for heavy-duty, high-cycle applications. Capacities typically range from 5 tons to 30 tons for grab lifting, with spans up to 35 meters.
TECHNICAL DATA
APPLICATION
1.This crane is extensively used in thermal power plants and coal handling yards, where it scoops coal from stockpiles or railcar dump hoppers and transfers it to crusher houses, conveyor feed hoppers, or furnace bunkers, operating continuously with high cycle efficiency and dust control measures.
2.It is essential in port terminals and river docks for bulk cargo unloading, handling materials such as iron ore, bauxite, phosphate, grain, fertilizer, and cement from ship holds to shore-side hoppers or storage piles, with fast cycle times to minimize vessel turnaround.
3.The crane is widely applied in steel mills and scrap recycling centers, using heavy-duty orange-peel grabs to handle shredded scrap, turnings, pig iron, and DRI (direct reduced iron) for furnace charging, baling press feeding, or railcar loading in harsh, abrasive conditions.
4.In cement plants, glass manufacturing facilities, and chemical fertilizer factories, this crane handles raw materials including clinker, gypsum, limestone, soda ash, pet coke, and sand, with sealed grab designs and dust suppression systems to minimize environmental pollution.
5.Additional applications include waste incineration plants, municipal solid waste treatment facilities, and biomass power stations, where the crane mixes, transfers, and feeds heterogeneous waste or biomass fuels (wood chips, bark, agricultural residues) into hoppers or combustion chambers, with grabs designed to resist corrosion and abrasion.

FEATURES
1
Double girder heavy-duty construction – two parallel box girders provide exceptional rigidity and stability for high-cycle grab operations, minimizing sway and ensuring accurate positioning of the grab bucket.
2
Dedicated grab hoist mechanism – features two rope drums (closing and supporting) or a motor-driven opening/closing system with synchronized rope reeving for positive grab control without slip or premature opening during transport.
3
High-duty grab bucket – available in clamshell (for coal, ore, grain), orange-peel (for scrap, rock, irregular shapes), or polyurethane-sealed (for fine powders, cement) designs, with replaceable wear liners and hardened steel tips.
4
Full electric travel with anti-swing control – independent motors for grab hoist, trolley travel, and gantry bridge travel, with optional VFDs and anti-swing systems to improve cycle times and reduce spillage.
5
Weather-resistant and dust-proof design – IP54 or higher electrical enclosures, sealed motors, corrosion-resistant paint systems, and optional dust covers for rail and electrical components to withstand outdoor and dusty environments.
