QD double-girder overhead crane with hook

The QD double-girder overhead crane with hook is a heavy-duty industrial overhead crane featuring a double main girder structure and equipped with a hook as the lifting attachment, enabling precise lifting and horizontal movement. It is widely used for lifting and handling materials in factories, warehouses, steel mills, hydropower stations, and other locations.

Whether it’s customized design for specific working conditions or lifting equipment meeting high safety standards, we can tailor solutions based on actual working conditions and on-site requirements. Free customized lifting solutions are available.

Lifting Hook Type Options

Overhead crane hooks can be divided into 4 types based on structure, application, and industry standards. When customizing a hook crane, please select the appropriate hook according to requirements. Below are the features and applications of each hook type:

• 1. General Purpose Hook (Specification: 3.2t-88t)

          Standard single hook block design, simple structure, low manufacturing cost, complies with DIN/ISO standards, safety factor ≥4 times. Suitable for a wide range of daily lifting operations, covering a broad load range (0.5~300 tons). Optional forged or laminated structure for high durability. Widely used in daily material handling such as factory warehouses, construction sites (hoisting rebar, precast components), and bulk cargo loading/unloading at port logistics centers.

• 2. Swivel Hook (Specification: 10t-400t)

        Built-in precision bearings allow 360°自由 rotation, preventing wire rope twisting. Utilizes double-row angular contact bearings with strong axial and radial load capacity. Some models are equipped with servo control for precise positioning (±0.5°), suitable for high-precision lifting or anti-rotation requirements for long materials. Widely used in shipbuilding (steel plate, pipe lifting), wind power (blade installation), automated production lines (requiring precise alignment), etc.

• 3. New Type Hook (Specification: 5t-600t)

        Made of high-strength alloy steel with optimized structural design, weight reduced by 15%~20% while maintaining strength. Complies with the latest FEM/ISO standards with higher safety factors. Widely used in high-end manufacturing (aerospace, automotive assembly), intelligent warehousing and logistics (automated lifting systems), heavy machinery (requiring high-strength, lightweight hooks), etc.

• 4. Specialized Hook (Specification: 5t-600t)

        Designed for electric/manual hoists with standardized interfaces; compact design suitable for small spaces; optional quick-release design for easy spreader更换. Widely used in light lifting in workshops (1~20 tons), maintenance work (equipment disassembly), material transfer on production lines (with hoists), etc.

Advantages & Features

Applications

•  QD overhead cranes are widely popular in numerous fields such as indoor and outdoor industrial and mining facilities, chemical industry, ferrous metallurgy, railway transport, ports and terminals, and logistics warehouses.  
•  In industrial and mining enterprise workshops, double-girder hook overhead cranes can lift raw materials, semi-finished products, and finished products. This greatly facilitates the efficient operation of the production process.
• For steel and chemical plants, it can move heavy equipment, steel, and chemical raw materials.
• In railway transport, it can assist in loading and unloading goods. At ports and terminals, it is a powerful tool for loading, unloading, hoisting, and transporting containers and bulk cargo. In logistics warehouses, it can efficiently handle the storage and transfer of various types of goods.
