Product Applications
Ideal for adjusting chain lengths in tower cranes, gantries, and hoists during high-rise construction. It ensures precise load positioning for steel beam installation, precast concrete handling, and scaffolding setups, enhancing safety and efficiency.
Used in overhead conveyors, assembly jigs, and robotic arms to maintain optimal chain tension. This reduces downtime in automotive, electronics, and other manufacturing lines, supporting quick tool-free adjustments for seamless production.
Essential for forklift attachments, automated storage systems (AS/RS), and pallet conveyors. It prevents chain slippage in high-frequency loading and unloading operations, improving safety and operational efficiency in warehouses and logistics centers.
Designed for shipyard cranes, anchor chain systems, and offshore rigging. Its rust-resistant features make it perfect for harsh saltwater environments, ensuring longevity and reliability in marine and offshore applications.
Withstands extreme conditions in mine hoists, drilling equipment, and power plants. The durable alloy steel construction supports heavy-duty loads (up to 20 tons), making it ideal for subterranean, high-temperature environments and energy sector operations.
Product Operate Guide
Check the lifting chain adjuster thoroughly. Ensure there are no cracks, deformations or other defects on the surface (verified by 100% magnetic particle inspection). Confirm that the anti - detachment stop pin or safety stop pin is intact and can work normally. Also, check if the specifications of the adjuster match the chain (e.g., a 6mm chain with a 1.12 - ton rated load adjuster).
Put the chain link to be adjusted into the inclined slot of the adjuster. Use the pin to connect the adjuster and the chain firmly. Ensure the chain is stuck in the correct position to avoid slipping during lifting.
After confirming the adjustment is correct, start the lifting operation. During the process, pay attention to the load, which must not exceed the rated load of the adjuster (e.g., 2 tons for the 8mm chain model). Avoid sudden lifting or dropping to prevent excessive force.
After the lifting is completed, remove the adjuster from the chain. Clean the surface of the adjuster to remove dust and debris. Store it in a dry and ventilated place to prevent rust, ensuring it can be used normally next time.
