Core Advantages

High-strength connection: Forged from high-strength alloy steel with exceptional tensile strength, capable of stably bearing heavy loads during hoisting and traction operations, serving as the core force-bearing component of the system.

Strong versatility: Flexibly connects various hoisting components such as hooks, chains, wire ropes, and shackles, adapting to diverse hoisting equipment and scenarios while simplifying the connection process.

Stable structure: Integral forging design without splicing gaps ensures uniform force distribution, preventing fractures from local stress concentration and enhancing operational safety.

Main Application Scenarios

Industrial hoisting: Used in cranes, overhead cranes and other equipment in factories and construction sites to connect spreaders with heavy objects (such as steel components and equipment) for lifting or transferring operations.

Construction machinery: Integrated with traction or hoisting functions of equipment such as excavators and loaders, connecting to operating accessories (such as grabs and hooks).

Logistics and transportation: Essential for container handling at ports and docks, connecting spreaders with containers, or used for traction and securing of large cargo.

Mining and infrastructure construction: Applied in mining and tunnel construction for pulling mine cars and hoisting construction materials (such as steel bars and pipelines).

Correct Usage Methods

Specification matching: Select the master link with appropriate rated load and dimensions based on the hoisting load and connected component sizes (such as chain pitch and wire rope diameter). Overloading is strictly prohibited.

Proper connection: Ensure full engagement of components (such as shackles and hooks) into the notches or holes of the master link, confirming secure connection without looseness or misalignment.

Load verification: Before commencing operations, perform a slight lift test to verify that the master link and entire connection system bear the load evenly without tilting or binding. Proceed with normal operations only after confirmation.

Key Precautions

Pre-use inspection: Conduct visual or tool-assisted inspection before each use. Immediately discontinue use and replace if the master link shows cracks, deformation, excessive wear (such as ring thickness below standard), or severe surface corrosion.

Overloading prohibition: Strictly adhere to rated load specifications. Overloading causes plastic deformation or fracture of the ring body, resulting in dropping accidents. Actual loads must remain below 100% of the rated value.

Avoid improper operations: Welding, cutting or structural modification of the master link is prohibited. During operation, prevent severe impacts to the ring body (such as sudden load drops or lateral pulling) to avoid damage from additional stress.

Regular maintenance: After extended use, maintain according to requirements, including cleaning surface contaminants and rust, applying lubricant to moving parts (if applicable), and storing in a dry, non-corrosive environment to prevent moisture and corrosion.

Compliance requirements: Select products meeting international or industry standards (such as ISO, ANSI, GB). Products lacking brand identification, specification markings, or quality inspection reports are prohibited.
