Roll Over Units to Lift and Rotate I-Beams

The roll over units are lifting and rotating equipment designed for heavy steel structures such as I-beams and H-beams. It is typically used in combination with overhead bridge cranes. With high strength load-bearing structure and synchronized rotation mechanism, the device enables controllable posture adjustment within rotation range of 0°–360°, meeting the requirements of welding, assembly, painting, and other multi-stage fabrication processes.

Working Principle of the Roll Over Units

During operation, the rotating equipment first securely clamps the I-beam using chain or belt lifting slings applied to the web or flanges of the steel section. The overhead crane provides the vertical lifting force, allowing the workpiece to be safely lifted off the ground. Once the load reaches a safe lifting height, the rotation drive system is activated. A motor combined with gearbox generates low-speed, high-torque output, driving the load to rotate smoothly to the target angle. Throughout the entire lifting and turning process, the center of gravity remains under controlled conditions, ensuring a stable, safe and impact-free rotation, significantly improving welding and assembly efficiency.

Performance Advantages of Lifting and Rotating Equipment

• Compared with traditional manual turning methods, this equipment can reduce I-beam turning time by 60% - 80%, significantly improving overall production efficiency.

• Fully mechanized operation eliminates manual prying and unstable lifting methods, reducing the risk of workplace injuries.

• It features automatic balance adjustment function, effectively preventing slipping or falling risks of the workpiece.

• Compatible with various standard sizes of H-beams and I-beams.

• Can be integrated with existing overhead crane in the workshop, reducing operating costs.

Case Study: Steel Component Turning Operations in Large Steel Mills

In a large steel structure fabrication plant, the rotator turning device was integrated into an overhead crane workstation for I-beam flipping and alignment adjustment during welding and assembly processes. After implementation, operators only needed a single lifting operation to complete both lifting and 180° smooth rotation of the I-beam, allowing quick switching between welding surfaces and precise positioning at assembly stations.

Actual operational results:

• I-beam turning cycle reduced from 8 - 10 minutes to 2 - 3 minutes

• Significant reduction in manual intervention and lifting accident rates

• Overall production line safety and continuous operation efficiency improved by up to 80%
