General purpose overhead crane
Weiyuan QE Type Double Trolley Overhead Crane
Product Overview
The Weiyuan QE Type 3+3 Ton Double Trolley Overhead Crane is a highly specialized lifting solution engineered for handling long, heavy, and awkward loads with superior stability and precision. Featuring two independent trolleys mounted on a robust double-girder frame, this crane allows for synchronized or separate operation, providing unmatched flexibility. This unique configuration is perfect for industries that regularly handle materials like pipes, timber, paper rolls, or structural steel, ensuring safe and efficient movement across your workshop or yard.
Product Advantages
Synchronized Lifting for Long Materials
The standout advantage of the QE model is its dual-trolley system. The two 3-ton trolleys can work in tandem to lift long and cumbersome items, maintaining balance and preventing dangerous load tipping or swinging. This synchronized control ensures that materials like pipes, rebar bundles, and long beams are handled safely and placed with precision, dramatically improving both safety and efficiency.
Independent Operation for Maximum Versatility
This crane offers more than just synchronized lifting. The two trolleys can also be operated independently, effectively turning your crane into two separate lifting points on a single bridge. This allows you to perform multiple smaller lifts simultaneously or handle different tasks in the same work area, doubling your productivity without the need for a second crane.
Robust Construction for Heavy-Duty Use
Engineered for a demanding A5-A6 work duty, the QE crane is built for reliability. The double-welded box girders are constructed from high-strength Q235B/Q345B steel, providing exceptional rigidity and a long service life. The trolley rails are made of high-strength hot-rolled flat steel, ensuring smooth and dependable travel even under constant use.
Advanced Safety and Control
Safety is our priority. The crane comes standard with a wireless remote control, allowing the operator to maintain a safe distance with a clear view of the entire operation. It is also equipped with a comprehensive safety system, including overload protection, emergency stop functionality, and travel limit switches for both the crane and trolleys, ensuring a secure working environment.
Application Scenarios
- Steel and Pipe Manufacturing: Ideal for lifting and transporting long steel pipes, rebar, and structural beams within the production plant or to storage yards.
- Lumber and Timber Yards: Perfectly suited for handling long logs, bundles of lumber, and other forestry products, facilitating easy loading and organization.
- Paper Mills: Efficiently lifts and moves large, heavy paper rolls, preventing damage and streamlining the production process.
- Precast Concrete Plants: Provides the stability and length needed to safely handle long precast concrete elements, such as panels and poles.

Frequently Asked Questions
Q: Can the two trolleys be operated at the same time?
A: Yes, that is the primary advantage of the QE crane. The trolleys can be operated simultaneously for lifting long objects, or they can be controlled independently to function as two separate cranes on one bridge, offering incredible operational flexibility.
Q: What is the benefit of a double-girder design for this type of crane?
A: A double-girder design provides superior strength, rigidity, and stability compared to a single-girder crane. This is especially critical for cranes with dual trolleys and wide spans, as it ensures the bridge can safely support the distributed load and resist twisting forces.
Q: Can this crane be used to turn over long objects?
A: Yes, with the proper rigging and skilled operation, the two independent hoisting mechanisms can be used to carefully flip or turn over long and heavy objects, such as large fabrications or molds. This is a common application in many manufacturing and maintenance facilities.
Q: What information do I need to get a quote for a QE crane?
A: To give you an accurate quotation, please provide the required capacity for each trolley (e.g., 3+3 tons), the span of your bay, the desired lifting height, your power supply details, and your preferred control method (wireless remote or cabin). It also helps to know what kind of materials you plan to lift.
