• Ring Clutch Lifting Device Application and Installation:

  Application:

  
  

  The Ring Clutch is widely used in the lifting, handling, and installation of precast concrete elements across various construction environments. It is ideal for panels, beams, columns, stair units, solid walls, hollow-core components, and other heavy precast structures requiring secure anchoring and controlled lifting. Its flexible shackle design allows multi-directional load engagement, making it suitable for complex site conditions and angled lifting operations. The device is commonly applied in precast factories, infrastructure projects, building construction, bridge components, and modular construction fields. With high strength, reliable locking, and compliance with safety standards, the Ring Clutch ensures stable and efficient lifting throughout the entire precast workflow. 

  
  

  Lifting Clutch Lifting Device Production Process

   

  The production of a Ring Clutch Lifting Device follows a strict, engineering-grade manufacturing workflow to ensure strength, reliability, and compliance with international lifting standards.

   

  Raw Material Selection

  High-strength alloy steel is selected for the lifting head, forged bolt, and shackle. All materials undergo chemical composition analysis to ensure consistent mechanical properties and traceability.

   

  Forging of Critical Components

  The lifting head and locking bolt are precision-forged to achieve superior density, structural integrity, and fatigue resistance. Forging also enhances impact performance required for heavy precast lifting.

   

  CNC Machining & Dimension Control

  All forged parts are CNC-machined to precise tolerances. The connecting surfaces, bolt holes, and locking mechanisms are finished to ensure smooth engagement with precast anchors.

   

  Welding of Hook Components

  The lifting hook is welded with thickened structural steel using certified welding procedures. Each weld must meet deep-penetration requirements and is verified through X-ray inspection to ensure zero internal defects.

   

  Heat Treatment & Hardening

  The bail and other major components are hardened and tempered to achieve the required balance of strength, toughness, and wear resistance. This process ensures stable performance under dynamic lifting loads.

   

  Assembly & Mechanical Testing

  Shackles, bolts, hooks, and lifting heads are assembled and tested for smooth rotation, secure locking, and correct anchor engagement. The device undergoes load tests to verify its rated capacity.

   

  Surface Treatment

  Components receive protective coatings such as galvanizing or painting to enhance corrosion resistance and extend service life, especially for outdoor or long-term construction environments.

• Ring Clutch Lifting Device Quality Inspection:

  Ring Clutch Lifting Device Quality Inspection

  
  

  The quality inspection of a Ring Clutch Lifting Device follows a strict, multi-stage control system to ensure every unit meets high safety and performance standards for precast concrete lifting.

  
  

  Raw Material Verification

  
  

  All alloy steel materials undergo chemical composition testing, hardness checks, and certification review before entering production, ensuring the required strength and consistency.

  
  

  Forging Integrity Inspection

  
  

  Forged lifting heads and bolts are tested for internal defects through ultrasonic or magnetic particle inspection. This guarantees dense structure, high toughness, and superior fatigue resistance.

  
  

  Dimensional and Tolerance Check

  
  

  CNC-machined parts are measured with precision instruments to confirm exact tolerances, ensuring smooth engagement with anchors and reliable locking performance.

  
  

  Welding Examination with X-Ray Testing

  
  

  The hook welding undergoes deep-penetration requirements and is inspected using X-ray equipment to detect hidden cracks, pores, or fusion defects, ensuring maximum structural reliability.

  
  

  Heat Treatment Validation

  
  

  Hardness and microstructure tests are performed after quenching and tempering to verify proper strength, ductility, and load-bearing consistency.

  
  

  Functional Testing

  
  

  Each assembled clutch is checked for smooth shackle rotation, accurate bolt locking, and secure anchor connection. Functional durability tests simulate real working conditions.

  
  

  Load Testing

  
  

  Every batch is subjected to proof-load testing—typically at 1.5× the rated load—to ensure the device performs safely under extreme lifting conditions.

  
  

  Surface Protection Check

  
  

  Coating adhesion, corrosion resistance, and surface uniformity are inspected to ensure long-term durability in harsh construction environments.

  
  

  Final Safety and Certification Review

  
  

  Each Ring Clutch is labeled with traceable identification and approved only after passing all safety standards, including those specified in Safety Regulations for Lifting Precast Concrete Units.
