  • Page 35: Chain Container

    6.2. Chain container (chain bag) Do not attempt to store more quantity of chain in chain container than that specified in the table. When containing more than the maximum specified quantity, it may result in serious damage to hoist and hazardous conditions to the operator and nearby people or goods. For the hoist with double chain-falls, the chain container should be installed with the unloaded load chain projecting by about 50cm.

  • Page 36: Chain Stopper In The Chain Container

    6.3. Chain stopper in the chain container. The chain stopper for slack fall stop is a safety component, not a functional one. Make sure that the stop is correctly fitted. The chain stopper of non-loaded side must be fixed 6inch (15cm) from the load chain end as shown in the left figure.

  • Page 37: Load Chain

    6.5. Load chain Check if the chain is twisted or not. Never try to use hoist when the load chains are entangled. Pull the bottom hook to the normal vertical position before use. Never use the lifting chain as a sling. Never twist the lifting chain.

  • Page 38: Checking Chain Alignment (The Welded Part Outward)

    Check the load chain for deformation or cracks. In this case, the wear on the chain guide and chain sheave should also be checked and they should be replaced if necessary. If a single link is defective in any way whatever, the chain must be replaced. If these limits are exceeded, the chain must be replaced immediately.
