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 Crane 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 (VFD) 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, finecorsa, arresto di emergenza, 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 gru a ponte to streamline material handling processes across various industries. Its key function is to securely grip different types of bulk goods—such as coal, ore, grano, sand, ghiaia, 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.
