General purpose overhead crane
Smart Double Girder Electric Grab Bucket Bridge Crane
Product Overview
The Weiyuan Smart Double Girder Electric Grab Bucket Bridge Crane is a heavy-duty, high-efficiency solution engineered for handling bulk materials. Designed for robust performance in demanding environments, this crane integrates a powerful double girder structure with a specialized electric or hydraulic grab bucket. It is built for reliability, strong bearing capacity, and safe operation. With customizable controls, including cabin, ground, and wireless remote options, this crane is perfect for transporting, assembling, loading, and unloading incompact goods across various industrial sectors.
Product Advantages
Heavy-Duty Construction
Features a strong, box-type double girder frame welded by machine for maximum rigidity and durability. This robust structure provides an exceptional bearing capacity, making it suitable for continuous, heavy-duty work cycles (A6 class).
Specialized Material Handling
Equipped with a high-performance grab bucket (mechanical or electro-hydraulic) designed specifically for bulk materials like scrap metal, garbage, minerals, or coal, ensuring efficient and secure handling.
Advanced and Safe Operation
Offers multiple control methods, including a commodious cabin with an open view, remote control for enhanced safety, and ground control. The system uses high-quality electrical components for durable and safe operation, with soft starting and stopping to minimize impact.
High-Quality Components
Wheels are manufactured through vacuum casting and medium frequency quenching for superior wear resistance. Key components like the wire rope drum, gears, and couplings are processed by a CNC machine center, ensuring top-quality control and a long working life.
Reliable Power and Drive
Powered by a heavy-duty slip-ring motor or an optional square cage motor with VVVF (Variable Voltage Variable Frequency) for smooth running. This ensures reliable performance, low noise, and efficient power consumption.
Application Scenarios
Waste Management and Recycling
Ideal for waste-to-energy plants and recycling centers for handling and moving large volumes of garbage and scrap materials. The grab bucket is designed to efficiently manage loose and irregularly shaped loads.
Ports and Terminals
Essential for port operations to load and unload bulk cargo such as coal, ore, and other minerals from ships and transport them to storage yards or other transport vehicles.
Mining and Quarries
Used in mining operations and quarries for the transport of raw materials and incompact goods, providing reliable performance in harsh and demanding work environments.
Steel Mills and Foundries
Perfect for steel mills and foundries to handle scrap metal, charge furnaces, and move bulk raw materials throughout the production facility, enhancing operational efficiency and safety.

FAQ
Q: What is the difference between a mechanical and an electro-hydraulic grab bucket?
A: A mechanical grab operates using the crane’s own wire ropes to open and close the bucket, making it simpler and cost-effective. An electro-hydraulic grab has its own integrated hydraulic power unit, offering stronger gripping force and more precise control, which is ideal for handling denser or more difficult materials. The choice depends on your specific material and operational needs.
Q: What information is needed to get a quote for this grab crane?
A: To provide an accurate quote, we need details such as the required lifting capacity, span (distance between runway rails), lifting height, the type of material you will be handling (to determine the right grab), power supply details (voltage/frequency), and your preferred control method.
Q: Can this crane be used outdoors?
A: Yes, the double girder grab crane is designed for use in a variety of environments, including outdoor goods yards, ports, and mines. We can provide additional weatherproofing features to protect the electrical and mechanical components from the elements.
Q: What safety features are included with the crane?
A: The crane is equipped with multiple safety devices, including an overload limiter, lifting and traveling limit switches, and an interlock protection device to ensure safe operation under all conditions.
Q: How is the crane installed?
A: We can provide comprehensive support for installation. Our senior engineers can be available on-site to guide the installation process and provide training for your team. Additionally, our sales and support teams are available to assist you throughout the process.
