Automated Bulk Grab Overhead Crane: Efficient Ore, Coal, Sand, and Slag Handling
The automated bulk grab overhead crane is composed of a bridge frame, long-travel and cross-travel mechanisms, a grab bucket, a remote monitoring system, and an electrical control system. It offers four control modes: fully automatic, semi-automatic, remote manual, and local manual. The crane adopts a double-girder, double-rail design, which is strong, durable, and provides high load-bearing capacity.
The automated bulk grab overhead crane can handle various bulk materials such as ores, slag, coke, coal, and sand, enabling loading, unloading, and material-handling operations.
Parameters
- Lifting Capacity: 5–20 tons
- Lifting Height: 6/9/12m/customized
- Span: 10.5–25.5 meters
- Working Duty: A6–A8
Features
- Easy Operation
The trolley is equipped with two sets of hoisting mechanisms, each using a twin-drum structure arranged symmetrically. This design ensures convenient operation, stable performance, high working efficiency, and strong load-bearing capacity. - Intelligent Warehouse Management
The automated bulk grab overhead crane is equipped with a dedicated warehouse management system for automated cranes, enabling yard management, operation management, equipment management, scheduling management, and report statistics. It interfaces with the user's production management system for task scheduling, achieving a high level of crane intelligence. - Real-Time Scanning
A 3D yard scanning system performs real-time scanning of the entire storage area to generate 3D point cloud data. The data is transmitted via a direct network cable to the point cloud processor and then sent through wireless networks and optical fibers to the warehouse management system, guiding the overhead crane to complete loading tasks. - High Automation Accuracy
5G communication technology is integrated into the video monitoring system and unmanned crane control system. Through 5G transmission, real-time 3D reconstruction, recognition, and analysis are performed in the cloud, with results returned to the site to guide production operations.
Advantages
The intelligent control system of the fully automated bulk grab overhead crane prioritizes safety and stability and offers the following advantages:
- Level-1 anti-sway standard (DB41/T1533-2018)
- CAP EMC certification
- Travel mechanisms support inching and creeping, with positioning accuracy up to 2 mm
- Edge-fuzzy control for smoother operation
Application Cases
Four 32-ton automated bulk grab overhead cranes used in the construction of a 2060 m³ blast furnace project for a steel company
Features
- Equipped with PLC control, positioning system, anti-sway control, and other intelligent integrated systems, ensuring precise positioning and efficient operation.
- The mechanical structure adopts a wide-box heavy-duty design with high fatigue resistance, suitable for high-temperature, high-humidity, and heavy-fog environments.
- Combined with an intelligent sensing system, the crane can automatically perform material grabbing, dumping, and transferring even under extremely low-visibility foggy conditions.
- No on-site operation is required; field management is carried out through a remote dispatching and management system, significantly reducing worker labor intensity.

Features
- Precision positioning within 5 mm: The automated bulk grab overhead cranes are equipped with 3D scanning, automatic positioning, automatic recognition, automatic obstacle avoidance, and automatic grabbing functions. The positioning accuracy for both fixed-point positioning and repeated operations is within 5 mm.
- Unmanned operation for greener production: Operators can easily control the cranes from an office located more than 1,000 meters away, avoiding exposure to dusty environments. Since its commissioning, the system has greatly reduced workers' labor intensity and ensured smooth machine operation.
