| Application of Load Turning Device for Steel Structures

In the steel structure manufacturing industry, large steel components often need to be turned, welded, assembled and inspected. Industrial load turning device can achieve smooth rotation and precise positioning of large steel structures, making them an essential auxiliary solution in steel structure production lines.

Why Steel Structure Manufacturing Need Load Turning Device

During steel structure processing, H-beams, box girders, steel plates and large welded components often require multi-angle welding, grinding, assembly and inspection. Due to the heavy weight and large dimensions of these workpieces, traditional crane-assisted manual turning methods present several challenges:

• Unstable turning process with potential swinging

• High level of manual involvement and safety risks

• Risk of workpiece collision or surface damage

• Limited welding angles affecting weld quality

Steel structure load turning units use synchronized drive control system to achieve smooth rotation and precise angle positioning, effectively solving the difficulties associated with traditional turning methods.

How Turning Device Ensure Safe Steel Structure Rotation

KUNFENG load turning device consists of load-bearing beam, synchronized driving mechanism, rotating system, lifting structure and safety control system. The equipment can be used together with overhead crane, gantry crane and other lifting systems.

Main Working Principles

• Smooth turning through dual-side synchronized drive

• High strength synthetic fiber slings to protect workpiece surfaces

• Variable frequency control for lowspeed and stable rotation

• Equipped with limit protection and anti-tilt safety systems

• Supports 0° - 360° continuous rotation or fixed-angle turning

Chain type slings are also available as an option. Flexible belt sling structures can effectively reduce surface indentation and localized stress on steel structures, making them ideal for painted components, stainless steel structures and high precision welded workpieces.

Heavy H-Beam Turning Applications: Improving Welding Efficiency and Quality

Since H-beams require multi-angle welding, traditional turning methods usually rely on repeated crane lifting, which is time-consuming and prone to positioning errors. Rotator turning devices utilize dual-side synchronized drive system to achieve smooth 90°, 180° and 360° rotation of H-beams, allowing workpieces to quickly reach the optimal welding position. This significantly improves welding efficiency and enhances overall production throughput.

Applications for Box Girder and Large Steel Structure Turning

Box girders are typically characterized by heavy weight, uneven center of gravity and complex structures. Traditional turning methods can easily lead to unbalanced loading and swinging. Steel structure turning devices use synchronized control systems to ensure balanced force distribution and support multi-point coordinated turning. Workpieces can be quickly rotated to the desired angle, making continuous welding and internal assembly operations more convenient for operators. For extra-long steel structures, customized dual-machine linkage or multi-point turning systems can be designed according to workpiece dimensions, ensuring stability and safety throughout the turning process.

How to Choose the Right Industrial Load Turning Device

• Select the appropriate load capacity according to the actual workpiece weight (load capacity up to 50 tons), while confirming the workpiece length, width and center of gravity.

• Choose 90°, 180° or 360° turning functions based on production requirements.

• Chain slings are available, flexible belt slings are recommended for painted or stainless steel workpieces.

• Choose manual spacing adjustment or electric control according to application conditions.

• Pay attention to safety configurations such as overload protection systems, anti-tilt protection, mechanical limit switches and emergency stop devices.
