A Special Lifting Tool for Heavy-duty Lifting——Double-hook Balance Lifting Beam for Double Girder Overhead Crane
This is a double-hook balance lifting beam (a special lifting tool for heavy-duty lifting). Its core information is as follows:
Technical Parameters:
| Lifting Capcity | 100 tons ( larger tonnage can be customizable ) |
| Size | Customizable |
| Compatible Crane Type | double girder overhead crane |
| Material | Q460 ultra-high strength steel (box-type welded structure, with built-in reinforcing ribs to prevent deformation) |
| Hook Assembly | High-strength forged hooks (material: 20CrMnTi), rated load per hook 50t, equipped with hook anti-slip buckle. |
| Sling spacing | Adjustable range 1500-3000mm (suitable for hoisting requirements of different long workpieces) |
1. Equipment Attributes and Structure
Type: Heavy-duty balance lifting beam (with matching double hook assembly)
Structural Form: Box-type high-strength steel welded structure, employing a double-hook load-distributing design; the lifting point spacing can adapt to the lifting needs of different workpieces.
Material: The main body is made of high-strength steel such as Q355B/Q460, with a yellow industrial warning coating on the surface (serving both corrosion resistance and visual warning functions).
2. Core Applications
Suitable for workshop bridge cranes, mainly used for lifting large, long, heavy-duty workpieces (such as heavy steel structural components, large equipment housings, long shaft components, etc.). Through the load-distributing effect of the double hooks, it achieves horizontal balance in lifting the workpiece, avoiding deformation or damage caused by workpiece tilting or uneven stress.
3. Key Design Features
Load Adaptability: The rated load of a single hook is typically ≥50 tons, and the overall rated load of the lifting beam can reach over 100 tons (specific model parameters need to be matched).
Safety Assurance: The lifting beam body must pass 1.25 times static load and 1.1 times dynamic load tests. Some models are equipped with hook anti-detachment devices, overload warnings, and other safety structures.
4. Typical Application Scenarios
Mainly used in industrial workshops such as heavy machinery plants, shipyards, and steel structure processing plants, undertaking operations such as the transfer of heavy-duty workpieces within the workshop and the relocation between assembly stations.
