PRODUCT INTRODUCTION
The Bulk Handling Rail Mounted Gantry Crane is a heavy-duty, high-capacity material handling solution designed for bulk cargo operations in ports, railway yards, and industrial terminals. Unlike rubber-tired gantries (RTGs) that offer flexible lane changing, the RMG operates on fixed steel rails, delivering superior positioning accuracy (±10–30 mm), high stacking density, and exceptional stability for continuous heavy-duty operations .
Equipped with a clamshell grab attachment instead of a container spreader, this RMG variant is purpose-built for handling dry bulk materials including coal, iron ore, grain, fertilizers, cement, and mineral concentrates. The crane features a robust gantry structure spanning multiple rail tracks or container rows, with a trolley traversing along the main beam to position the grab precisely over cargo holds, stockpiles, or receiving hoppers .

APPLICATION
1. Bulk Cargo Terminals & Ports
The RMG with grab attachment excels at unloading bulk carriers and transferring materials such as coal, iron ore, and grain from vessels to shore-side conveyors or storage yards. The fixed rail system enables precise grab positioning over narrow hatch openings, minimizing spillage and maximizing productivity. Typical throughput rates range from 500 to 1,500 tons per hour depending on configuration.
2. Railway Freight Yards
In intermodal rail terminals, the RMG loads and unloads bulk materials from railcars, transferring cargo between trains and trucks or stockpiles . The crane spans multiple railway tracks, allowing it to service several railcars without repositioning. Applications include coal train unloading, grain hopper car loading, and aggregate transfer operations.
3. Power Plant Coal Receiving
Coal-fired power plants rely on RMG cranes for consistent, high-availability coal intake from railcars or barges. The electric drive system ensures quiet, emission-free operation while the heavy-duty grab handles the abrasive nature of coal with minimal maintenance . The crane's ability to stack high and wide maximizes fuel stockpile density.
4. Steel Mill Raw Material Yards
The RMG handles iron ore, limestone, coke, and scrap metal in steel mill yards . Equipped with heavy-duty grabs or magnetic attachments, the crane feeds blast furnaces and storage areas with precision. The robust steel structure withstands the harsh, dusty environment of metallurgical operations.
5. Industrial & Manufacturing Facilities
Cement plants, chemical works, and mining operations utilize RMG cranes for handling bulk raw materials and finished products . The outdoor-rated design with marine-grade corrosion protection ensures durability in exposed environments, while the electric drive delivers low operating costs compared to diesel alternatives.
