General purpose overhead crane
Weiyuan QZ Type Double Girder Grapple Crane
Product Overview
The Weiyuan QZ Type 15 Ton Double Girder Grapple Crane is a heavy-duty lifting powerhouse engineered specifically for handling bulk materials. Comprised of a robust box-shaped bridge, a high-performance grab trolley, and an advanced electric control system, this overhead crane excels in demanding environments like scrap yards, waste management facilities, and bulk cargo ports. Its specialized grab bucket is designed to capture and move loose materials with exceptional efficiency and precision, making it an indispensable asset for industries that require reliable, high-volume material handling.
Product Advantages
Superior Bulk Handling Efficiency
The core advantage of the QZ crane is its specialized grab mechanism. The powerful grab bucket, available in two-lobe or four-lobe configurations, is designed to capture large volumes of bulk materials—from scrap metal and garbage to grain and coal. The dedicated switching and lifting mechanisms allow for rapid opening and closing, ensuring fast cycle times and maximizing your operational throughput.
Heavy-Duty Construction for A6 Work Duty
Engineered for a demanding A6 work duty classification, this crane is built to withstand continuous, intensive use. The main girders are constructed from high-strength Q235B or Q345B steel, processed with CNC cutting for absolute precision. This robust framework, combined with a durable winch trolley, guarantees a long service life and unwavering performance in the toughest industrial settings.
Advanced Control and Safety Systems
Operator safety and control are paramount. This crane offers flexible control options, including a comfortable, air-conditioned cabin for maximum visibility and a wireless remote control for enhanced operational safety and flexibility. It is equipped with a full suite of safety devices, including overload limiters, travel limit switches, and an emergency stop system, to protect your personnel, cargo, and equipment.
Fully Customizable for Your Application
We understand that no two jobs are the same. We offer complete customization to tailor this crane to your specific needs. You can configure the lifting capacity (from 5 to 20 tons), span (up to 31.5m), lifting height, and power supply. We work with you to select the ideal grab type and capacity for the materials you handle, creating a truly bespoke lifting solution.
Application Scenarios
- Scrap Steel and Metal Recycling: Ideal for loading, unloading, and sorting large quantities of scrap metal in recycling yards and steel mills.
- Waste-to-Energy and Garbage Disposal Plants: Efficiently handles municipal solid waste, moving it from tipping floors to incinerators or processing lines.
- Ports and Terminals: Perfect for unloading bulk cargo like coal, grain, and minerals from ships and barges with speed and reliability.
- Construction and Mining: A powerful solution for moving large volumes of sand, gravel, and other loose materials on large-scale project sites.

Frequently Asked Questions
Q: What is the main difference between a grapple crane and a standard hook crane?
A: A standard hook crane is designed for lifting singular, heavy objects that can be secured with slings or chains. A grapple crane, like our QZ model, is specifically designed to handle bulk materials—such as scrap, waste, or grain—using a specialized grab bucket that can scoop and hold loose items.
Q: What type of grab bucket do I need for my materials?
A: The right grab bucket depends on the material you are handling. For instance, a multi-lobe (orange peel) grab is excellent for irregular scrap metal, while a clamshell bucket is better suited for fine materials like sand or grain. Our engineering team will help you select the perfect grab design and capacity for your application.
Q: Can this crane be operated outdoors?
A: Yes. While the standard configuration is for indoor use, the crane can be fully prepared for outdoor environments. This includes adding rain covers for the hoist and electrical components and using special corrosion-resistant paint to protect it from the elements.
Q: What information is needed to get an accurate quote for a 15-ton model?
A: To provide you with a fast and accurate quote, please share the following details: required lifting capacity (15 tons), the span of your runway, the necessary lifting height, your facility’s power supply (e.g., 3-Phase 380V 50Hz), the type of material you will be lifting, and your preferred control method (cabin or remote).
