Specialized Lifting Tool for Circular Industrial Work-pieces
I. Introduction:
Main Equipment: An industrial lifting tool employing a multi-point/multi-link mechanical structure. The main body is light gray, with key load-bearing parts reinforced in yellow. Connected via a crane hook, it achieves precise clamping of cylindrical workpieces.

Technical Parameters:
| Rated Lifting Capacity | 5t - 300t | Customized oversized models available based on crane rated load |
| Compatible Workpiece Diameter | φ800mm - φ3000mm | Compatible with different sizes of steel coils/cylindrical forgings, supports diameter adjustment |
| Clamping Method | Mechanical self-locking clamping | Multi-link linkage, even force distribution, suitable for cylindrical curved surfaces |
| Structural Form | Multi-link mechanical clamping structure | The image shows a multi-support linkage architecture, stable clamping, and distributed force distribution |
| Working Speed | Opening/Closing Speed | 0.5-2m/s (adjustable) | Adapts to lifting rhythm, balancing efficiency and safety. |
| Function Expansion | Add a hydraulic rotation mechanism (to achieve workpiece...) Features include: 360° rotation, weighing sensor, and remote control module |
| Workpiece Adaptability | supports customized clamping structures for irregularly shaped cylindrical parts and steel coils with mandrels. |
Working Materials: Large cylindrical metal workpieces (steel coils/metal forgings), with a metallic surface, large volume, and high weight, representing core processing/storage materials in heavy industry.
Operating Environment: Heavy industrial workshops with corrugated metal walls, steel structure beams on the ceiling, and industrial lighting. The overall setting is a heavy industrial production/storage scenario for steel and machinery manufacturing.
II. Equipment Attributes
This equipment is a specialized lifting tool for circular workpieces, belonging to non-standard industrial lifting equipment, specifically designed for lifting, transferring, and stacking cylindrical and tubular materials.
III. Core Application Scenarios
Steel/Metallurgical Industry: Workshop transfer, warehouse stacking, and production line loading/unloading of metal coils such as steel coils, aluminum coils, and copper coils.
Heavy Machinery Manufacturing: Lifting, handling, and process coordination of large cylindrical parts, molds, and forgings.
Chemical/Food Industry: Safe lifting of stainless steel drums, chemical raw material drums, and food processing drums.
Building Materials/Precast Components Industry: Lifting operations of cylindrical precast components and pipe piles.
IV. Core Advantages
**Precise Adaptability:** A dedicated circular clamping structure ensures even force distribution, preventing workpiece surface scratches and deformation, and is suitable for cylindrical materials of different diameters.
High Efficiency: Compatible with crane linkage, allowing single-person lifting and transfer, significantly reducing process time and suitable for continuous production.
Strong Safety Performance: Equipped with a self-locking and anti-derailment structure, ensuring stable clamping under heavy loads and avoiding the risk of slippage and workpiece tipping.
Excellent Durability: Constructed from high-strength steel, treated for rust prevention and wear resistance, impact-resistant and corrosion-resistant, suitable for heavy-duty, high-frequency industrial conditions.
Low maintenance costs: The structure is simple, there are few points of failure, and only basic lubrication and inspection are required on a daily basis, so maintenance costs are controllable.
