Overhead Crane Slung Load Rotator for Lifting

KUNFENG load rotator is an industrial lifting auxiliary equipment installed below the hook of an overhead crane, designed for lifting, rotating positioning and assembly operations of large workpieces. The rotator adopts an electric drive system combined with rotating mechanism and control system, enabling safe 360° rotation and orientation adjustment of suspended loads in the air. It effectively replaces traditional manual turning methods, improves production efficiency and reduces operational risks.

Working Principle of Electric Powered Load Rotator

The load rotator is installed between the overhead crane hook and the lifted workpiece, working together with the overhead crane through connecting mechanism. During operation, the overhead crane is responsible for vertical lifting and horizontal movement of the workpiece, while the load rotator uses electric motor to drive the internal rotating mechanism, allowing the suspended workpiece to rotate in the required direction.

Operators can adjust the rotation speed and direction through the control system, achieving 360° continuous rotation or precise positioning at a specific angle. During welding, inspection and assembly processes of large workpieces, the rotating device maintains stable load positioning, reduces impact and swinging during lifting operations, and improves operational accuracy.

Advantages of Overhead Crane Slung Load Rotator

• Rotates loads with overhead cranes, avoiding direct manual involvement in turning operations and enhancing workplace safety.

• Quickly adjusts workpiece angles, reduces repeated lifting, and improves production line efficiency.

• With variable frequency control and precision reduction mechanisms, the device runs at adjustable speeds and supports accurate angle stopping as required.

• The rotator can be integrated with existing overhead cranes or gantry cranes, helping reduce additional equipment investment.

• Customizable according to workpiece weight, dimensions, rotation mode and on-site layout, providing tailored turning solutions for actual production.

Case Study: 10-Ton Rotator Turning Device Exported to a Steel Manufacturing Factory in Brazil

A steel manufacturing company in Brazil needed to rotate 10-ton steel structural components for welding, inspection and subsequent processing during large-scale steel structure production. Based on the workpiece dimensions, weight and workshop layout provided by the customer, KUNFENG designed a overhead crane slung rotator device. The turning system features electric drive mechanism and was integrated with the existing overhead crane to achieve stable lifting and 360° rotation of large steel components.

After commissioning the turning system:

• Reduce manual assistance during workpiece turning operations;

• Improve the processing efficiency of large steel structures;

• Minimize safety risks during lifting and rotation processes.

This customized solution effectively improved the customer's production efficiency and operational safety.

How to Select the Right Electric Rotator Turning Device

• Select the rated load capacity based on the maximum workpiece weight

• Clarify workpiece dimensions and rotation requirements

• Choose appropriate rotation speed

• Decide between manual or electric adjustment for lifting point spacing

• Determine chain slings or belt slings according to workpiece characteristics

• Optional wireless remote control available

• Confirm industrial power supply voltage
