Crane clamp is a key component directly contacting the load within a lifting system. Proper selection directly affects lifting safety and operational efficiency. Improper selection may cause load instability, slipping, or equipment damage. Such risks increase safety hazards and affect production schedules. Different industries and conditions vary in load form, weight, and environment. Crane clamp must be scientifically matched to application requirements for safe and stable operation.
Basic Types of Crane Clamp
Steel Plate Clamp
Steel plate clamp is mainly used for lifting single or multiple steel plates by gripping plate edges.
•Features: Steel plate clamp uses mechanical self-locking or lever clamping structures, enabling single-point or multi-point gripping.
•Application advantages: Suitable for horizontal or vertical lifting of steel plates and profiles, offering firm gripping and flexible operation.
Coil Clamp
Coil clamp is suitable for lifting cylindrical coil materials such as steel coils.
•Features: Coil clamp adopts internal support or external gripping structures, ensuring uniform load distribution and reduced deformation.
•Application advantages: Suitable for horizontal or vertical lifting of steel coils and aluminum coils.
Pipe clamp
Pipe clamp is designed for lifting pipes and tubular materials with anti-rolling protection.
•Features: Pipe clamp uses multi-point gripping or curved contact structures to prevent rolling and eccentric loading.
•Application advantages: Suitable for pipes and cylindrical components, improving stability and reducing manual assistance needs.
Lifting Beam and Combination Clamp
Lifting beam and combination clamp are used for large-span, heavy, or irregular components with multi-point load sharing.
•Features: Lifting beam enables flexible combinations and balanced force distribution across multiple lifting points.
•Application advantages: Suitable for oversized or irregular loads, reducing single-point stress risks and improving overall safety.
Bulk Material Grab
Grab is a specialized lifting device for bulk and block materials such as coal and ore.
•Features: Grab uses opening and closing mechanisms and includes mechanical, electric, and hydraulic types.
•Application advantages: Suitable for bulk material handling with high efficiency and automation in ports and power plants.
Customized Special Clamp
Customized special clamp is developed for special conditions or non-standard loads with personalized designs.
•Features: Customized special clamp offers flexible structures and functions, achieving high compatibility with crane systems.
•Application advantages: It meets special shape, environment, or safety requirements beyond standard clamp capabilities.

Key Considerations for Crane Clamp Selection
Characteristics of the Lifted or Grabbed Load
Load characteristics are the primary basis for crane clamp selection.
•Define material weight, volume, and geometry to ensure rated capacity and load structure meet requirements.
•Identify whether materials are bulk, block, or finished components, as gripping requirements differ significantly.
•For grab-type clamps, consider surface condition and flowability, including moisture, particle size, and stacking behavior.
Lifting Conditions and Operating Environment
The operating environment significantly affects crane clamp design and material selection.
•Indoor or outdoor use: Determine exposure to wind load, rain, and temperature variation.
•Dusty, high-temperature, or corrosive environments: Clamps require wear resistance, heat resistance, and corrosion protection.
•Continuous operation frequency and automation needs: High-frequency operations require higher reliability and lower maintenance.
Safety and Compliance Requirements
Safety is the core principle in crane clamp selection.
•Rated load and safety factor: Clamp capacity must match operating conditions and design standards.
•Grab closing force and anti-leakage design: Prevent material spillage during lifting and transportation.
•Applicable industry standards and regulations: Ensure long-term operational safety and regulatory compliance.
Compatibility with the Crane System
Crane clamp must match the complete lifting system.
•Clamp types should be structurally and functionally compatible with overhead crane and gantry crane systems.
•Powered clamps such as grabs must coordinate with hoisting mechanisms and electrical control systems.
•Electric grabs require compatible power supply, control circuits, and operating logic.
