load chain/hard chain/safety chain

详情

To achieve the consistent high level of quality and reliability of our products.
 Electronically controlled chain machines have been specially built and developed to provide   advanced manufacturing processing.
 High grade alloy steel are carefully chosen.
 Strict control of material acceptance and processing is carried out by skilled personnel.
 Sophisticated multi-process heat-treatment techniques have been developed.
 Non-destructive testing systems are used with magnetic crack detection (magna flux   system),being applied during final inspection.
 All accessories, such as hooks, connectors etc.,are produced by special hot forging techniques   carried out on modern forging hammers.
 Close dimensional controls are carried our at all stages of manufacture.
 
To ensure the chains have a high capacity to absorb shock loadings, they are produced so that they will give a minimum extension of *0% under a destruction test before fracture occurs.They are also subjected to sample bend testing.
