Description of Chart Columns
Chain Grade: Indicates the strength and quality of the chain. Higher grades have thicker wires and are designed for more demanding applications.
Pitch (mm): The center-to-center distance between adjacent pins, measured in millimeters.
Wire Diameter (mm): The diameter of the wire used to make the chain links, measured in millimeters.
Pin Diameter (mm): The diameter of the pins that interlock with the chain links, measured in millimeters.
Minimum Breaking Load (MBL - kN): The theoretical maximum force the chain can withstand before breaking, expressed in kilonewtons.
Weight per Meter (kg): The weight of one meter of chain, measured in kilograms.
Working Load Limit (WLL - % of MBL): The safe working load for the chain, typically expressed as a percentage of the MBL. This percentage varies based on industry standards and the application's risk factors.
Applications: Suggested uses for each chain grade, ranging from light to severe-duty applications.
Additional Information
Chain Length: Standard chain lengths are often provided in multiples of the pitch or in specific increments (e.g., 1 meter, 2 meters, etc.).
Attachment Compatibility: Information on the types of hooks, shackles, or other attachments that are compatible with the chain size.
Special Features: Any special features such as galvanized coating for corrosion resistance, or marked chain for identification.
Safety Standards: Compliance with safety standards such as OSHA, ANSI, or CE.
Notes
Always refer to the manufacturer's specific chain size chart for precise measurements and ratings.
Ensure that the chain selected meets the requirements of the application and adheres to all relevant safety regulations.
Regular inspection and maintenance are crucial to ensure the chain's continued safe operation.
