抓斗桥式起重机

A grab bucket overhead crane is a specialized material handling machine designed to streamline the grabbing, 举起, and transportation of bulk materials like coal, 矿石, 粮食, 沙, and gravel. As a critical piece of equipment in industrial and mining operations, this crane combines the stability of an overhead bridge structure with the powerful gripping force of a grab bucket—making it ideal for businesses seeking to boost productivity, cut labor costs, and ensure safe bulk material movement. Whether you’re operating in a mine, power plant, port, 或建筑工地, a high-quality grab bucket overhead crane delivers consistent performance for heavy-duty material handling tasks.

Key Features of Our Grab Bucket Overhead Crane

Our grab bucket overhead crane is engineered with industrial-grade components to meet the demands of harsh working environments. Here are its standout features:

• 1. High-Strength Main Beam: Constructed from premium Q355B steel using welding forming technology, the main beam undergoes strict flaw detection to ensure exceptional load-bearing capacity and fatigue resistance. Its optimized box-type structure reduces self-weight while maintaining rigidity, enabling stable operation even under maximum rated loads.
• 2. Wear-Resistant Grab Bucket: Available in clamshell, orange-peel, and bulk grab designs to match different material properties. The bucket body is made of Mn13 wear-resistant manganese steel, significantly extending service life. The opening/closing mechanism uses a high-torque hydraulic cylinder or planetary reducer for smooth, reliable grabbing action.
• 3. Precision Frequency Conversion Control: The lifting mechanism features a high-efficiency motor and hard-tooth surface reducer for strong power and stable speed regulation. The bridge and trolley traveling systems use frequency conversion (变频驱动) for smooth starts/stops, minimizing impact on the crane structure and materials. Anti-derailment devices are standard on all running gears.
• 4. Advanced PLC Electrical System: Equipped with Siemens/Mitsubishi PLC and a user-friendly HMI for intuitive operation and real-time monitoring. Integrated safety functions include overload protection, 限位开关, 紧急停止, and fault diagnosis—enhancing overall safety and equipment reliability. Optional wireless remote control allows operators to work from a safe distance.

What is A Grab Bucket Used For?

A grab bucket is a specialized attachment designed for efficiently grabbing, holding, and releasing bulk materials. It works in tandem with equipment like 桥式起重机 to streamline material handling processes across various industries. Its key function is to securely grip different types of bulk goods—such as coal, 矿石, 粮食, 沙, 碎石, and non-corrosive chemicals—eliminating the need for manual loading or unloading. Different grab bucket designs (clamshell, orange-peel, bulk grab) are tailored to specific material properties: clamshell grabs excel at fine or powdery materials, orange-peel grabs handle irregular items like scrap metal, and bulk grabs are ideal for dense, heavy materials. By providing a reliable and efficient way to move large quantities of bulk materials, grab buckets significantly boost operational productivity and reduce labor intensity.
