In the industrial sector, spanning from construction sites to freight ports, and from production workshops to logistics warehouses, crane spreader serves as the core equipment that supports the efficient operation of various industries. However, crane spreader comes in a wide range of types with distinct functions. How to achieve precise selection for different application scenarios is a practical issue that enterprises must address to ensure production safety and improve operational efficiency. Next, we will first introduce the types of crane spreader, and then provide suitable selection solutions based on specific scenarios. This will enable you to quickly match the right crane spreader, effectively avoid safety risks and cost wastes caused by incorrect selection, and help enterprises carry out operations safely and efficiently.

Types of Crane Spreader

1. Lifting Hooks

Classified by function and structure, crane spreader mainly falls into five core categories: lifting hooks, lifting rings, lifting suction cups, lifting clamps, and lifting beams.

As the most basic type of crane spreader, lifting hooks connect cranes to ropes or heavy loads. They are typically forged from high-strength alloy steel and commonly come in two structural types: single hooks and double hooks.

Features
Simple structure, easy installation, high load-bearing capacity, and wide application range.

Application Scope
Used to connect cranes with ropes, they can lift various regular heavy loads equipped with lifting lugs or secured by rope binding—such as machine tools, box-type components, and the like.

2. Lifting Rings
Description
Lifting rings are specialized connecting components that provide fixed lifting points for standard equipment or irregularly shaped structural members, serving as transition parts between cranes and the loads being lifted. Most lifting rings are formed through integral forging or welding, and are fixed to the surface of the load via threaded connections (detachable) or welding (fixed type).
Features
They can withstand multi-directional tension, offer strong connection stability, and ensure controllable lifting angles—making them fundamental components for safe lifting operations.
Application Scope
They are suitable for scenarios involving standard equipment without pre-set lifting points (such as electric motors and pump bodies), large structural members (such as hull sections and steel box girders), and situations requiring long-term or high-frequency lifting.

3. Lifting Suction Cups

Description
As specialized crane spreader that secures workpieces via physical adsorption force, lifting suction cups require no binding or drilling. They are mainly categorized into two types: vacuum suction cups and magnetic suction cups.
Vacuum Suction Cups
Description
Vacuum suction cups create negative pressure by extracting air between the cup and the workpiece, and achieve adsorption relying on atmospheric pressure. They do not damage the workpiece surface and provide relatively uniform adsorption force.
Application Scope
They are suitable for lifting non-magnetic, flat heavy loads such as glass, steel plates (with smooth surfaces), plastic plates, and stone materials.
Magnetic Suction Cups
Description
Classified by magnetic force type, magnetic suction cups include electromagnetic suction cups and permanent magnetic suction cups. They can adsorb magnetically conductive metals using magnetic force. Featuring fast adsorption speed, they are only suitable for magnetically conductive lifting operations.
Application Scope
They are used for lifting magnetically conductive heavy metal loads such as steel materials, steel billets, cast iron parts, and steel rails (frequently applied in the metallurgical and machinery industries).

4. Lifting Clamps
Description
As specialized crane spreader that secures workpieces via mechanical clamping force, lifting clamps are divided into two main types: lifting tongs and C-beam lifting clamps.
Lifting Tongs
Description
Composed of alloy steel clamp bodies, adjusting screws, and anti-slip teeth, lifting tongs clamp the edges or sides of workpieces using mechanical force. They offer secure clamping and strong adaptability, and can also adjust the clamping range according to the size of the workpiece.
Application Scope
They are suitable for long strip-shaped or sheet-shaped metal workpieces without lifting lugs, such as steel plates, section steels (e.g., I-beams, angle steels), and steel pipes.
C-Beam Lifting Clamps
Description
C-Beam lifting clamps adopt a C-shaped clamp body and use the eccentric clamping principle to secure workpieces, preventing slippage during lifting. They are suitable for cylindrical or coiled workpieces, featuring strong clamping stability and easy operation.
Application Scope
They are used for lifting cylindrical or annular heavy loads such as coiled materials, cylinders, and round steel.

5. Lifting Beams
Description
Lifting beams can change the force direction of lifting operations and do not directly grip heavy loads—they must be used in conjunction with lifting hooks or clamps. Most lifting beams are fabricated by welding high-strength alloy steel and can be equipped with multiple lifting points.
Features
They can reduce the height of lifting slings, prevent deformation of lifted objects, enable lifting over obstacles, and ensure stable lifting postures.
Application Scope
They are suitable for: large long-span components (e.g., precast floor slabs, steel box girders); deformable workpieces (e.g., glass curtain walls, thin steel plates); and lifting scenarios where obstacles need to be crossed (e.g., lifting workshop equipment over production lines).

Seection and Solutionsl

Below is a summary of suitable rigging selections and corresponding solutions based on core requirements across different scenarios.

Application scenarios	Core requirements	Lifting Gear Type	Solutions and Operation Key Points
Lifting of Machine Tools and Equipment in the Machinery Manufacturing Industry	Universality and Adaptability	Hook	1. It adopts a double-hook structure with safety latches, which effectively prevents slings from detaching from the hooks during lifting operations.2. When used in conjunction with wire rope slings, it enhances the connection stability between the lifting device and the equipment's lifting lugs.3. Before operation, check the wear condition of the hook body to ensure that the wear amount is less than 10% of the original size, thus guaranteeing safe load-bearing.
Lifting of Hull Blocks in the Shipbuilding Industry	Reliable and Standard Connection Points	Lifting Eye	1. A 30-ton integral alloy lifting eye is selected as an option to ensure the rated load is matched;2. When used in combination with explosion-proof shackles, it enhances connection reliability under complex outdoor working conditions;3. The angle of the lifting eye is fine-tuned by the crane, and its multi-directional load-bearing characteristic is utilized to achieve precise alignment of the hull blocks.
Lifting of Large Glass Panels in Glass Processing Plants	Non-destructive Protection and Scratch Prevention	Lifting Suction Cup	1. Equipped with a vacuum monitoring system, it ensures the stability of the adsorption force in real time and prevents glass from falling off.2. The suction cup is made of ultra-soft rubber material, which controls the glass scratch rate below 0.05%.3. The electric adsorption response time is ≤ 2 seconds, which matches the rhythm of assembly line operations and improves lifting efficiency.
Lifting of Section Steels in Steel Plants	Efficient, Specialized, and Safe Clamping	Clamp / Clamping Tong	1. It adopts a high-temperature-resistant anti-slip tooth design, which enhances the clamping friction force on section steels and prevents loosening under high-temperature working conditions.2. The adjustable structure is suitable for section steels with a width of 100-300mm, meeting the needs of batch lifting of multiple specifications.3. Regularly perform high-temperature lubrication and maintenance on movable parts to reduce wear and extend service life.
Lifting of Precast Floor Slabs in the Construction Industry	Maintaining Balance, Preventing Deformation, and Increasing Working Space	Lifting Beam	1. Set the distance between the lifting points of the balance lifting beam to 4 meters, aligning it with the center of gravity of the floor slab to prevent tilting or fracture during lifting.2. The two ends of the lifting beam are equipped with rotating hooks, which can flexibly adapt to the stacking angle of the floor slabs and facilitate quick hooking operations.3. During the lifting process, hoist slowly and steadily. Utilize the balancing function of the lifting beam to keep the floor slab horizontal, avoiding concrete detachment caused by tilting and ensuring the integrity of the component.

o summarize, the selection of crane spreader is by no means a trivial matter—it serves as the critical safety link between lifting machinery and the loads being lifted. Proper selection is not only the fundamental prerequisite for eliminating safety accidents and safeguarding the safety of personnel and equipment, but also a key decision for improving operational efficiency, protecting the integrity of workpieces, and achieving cost-effective and efficient production. Therefore, before each lifting operation, it is essential to adopt a rigorous attitude of "safety first and adapting to the load characteristics." Accurate analysis and selection must be conducted based on the specific properties of the load, ensuring that the most suitable lifting gear becomes the most reliable guarantee for safe production.
