What is Turning Device at the Crane Hook

In modern industrial production, many heavy workpieces need to be turned from one side to another during processing, assembly or inspection to facilitate loading and unloading, welding, spraying or quality inspection. Turning device at the crane hook (also known as turnover spreader beam) is a special additional device for this purpose. It can rotate or turn the workpiece on the hook smoothly and accurately to any angle, greatly improving the work efficiency and safety.

Load turning device for crane

Composition and working principle of turning device

● Hook connection mechanism: directly connected to the crane hook to carry the load weight.

● Turning mechanism: precise rotation is achieved through the motor-driven gear set.

● Control unit: wired remote control or wireless remote control, supporting multi-speed regulation; some smart models are equipped with angle sensors, which can preset the turning position.

● Safety device: built-in overload sensor, electronic limit switch and mechanical stop, real-time detection of load and rotation angle, automatic alarm and stop movement once the limit is exceeded.

Main advantages of turning device at the crane hook

● One-button start of the rotation program can complete multi-angle turning of large pieces, saving the complex process of traditional manual turning.

● Combined with digital control or PLC, it can be accurately docked at any angle to meet the positioning requirements within ±1°.

● The turning process is smooth and jitter-free, the automatic balancing system eliminates inertial impact, and multiple limit and emergency stops are used to ensure safe operation.

● It can not only hoist steel structures and heavy castings, but also is suitable for automobile chassis, pipeline assembly and ship component turning.

Lifting and rotating beam

Typical application scenarios

● Steel structure manufacturing: large H-beam, steel plate flanging, box beam turning operations.

● Automobile assembly: multi-angle turning and welding of chassis assembly and body components.

● Casting and forging: sand box turning, mold angle calibration.

● Logistics and warehousing: container unloading, hopper emptying.
