PRODUCT INTRODUCTION
The Grab-type Single Boom Level Luffing Portal Crane is a specialized bulk material handling solution designed for high-efficiency loading and unloading of dry bulk cargo at ports, terminals, and storage yards. Characterized by its single straight boom structure and wire rope luffing mechanism, this crane enables full-load luffing with horizontal load displacement—a critical feature for continuous bulk handling operations. The portal frame design allows vehicles and cargo to pass beneath, maximizing space utilization on congested wharf aprons. Equipped with a four-rope clamshell grab and offering 360° continuous rotation, this crane delivers rapid cycle times and throughput rates of up to 1,500 tons per hour for materials including coal, iron ore, grain, fertilizer, and mineral concentrates.

1.Bulk Cargo Terminals – High-speed unloading of coal, ore, grain, and fertilizer from vessels directly to shore conveyors or stockyards. The single boom level luffing design ensures horizontal load movement, minimizing material spillage during the luffing cycle.
2.Port & Wharf General Cargo Operations – Versatile handling of both bulk and general cargo using quick-change attachments (grab, hook, or container spreader). Ideal for multi-purpose terminals requiring operational flexibility.
3.Power Plant & Industrial Docks – Captive raw material intake for coal-fired power plants, steel mills, and manufacturing facilities, feeding directly into plant material handling networks.
4.Transshipment & Multimodal Hubs – Efficient transfer of bulk materials between ships, barges, rail cars, and trucks. The crane's gantry travel capability allows it to service multiple berth positions along the quay.
5.Storage Yard Stacking/Reclaiming – Loading and unloading bulk material stockpiles, with the single boom design providing extended reach and full-circle working range.
