| Safety with Grade 80 |
| To achieve the consistent high level of quality
and reliability of our products |
 |
Electronically controlled chain making 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 persons. |
|
|
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
carred out on modern forging hammers. |
|
Close dimensional controls are carried out
at all stages |
| |
of manufacture |
|
| To ensure the chains have a high capcvity to
absorb shock loadings, they are produced so that they will
give a minimum extension of 20% under a destruction test before
fracture occurs. |
| They are also subjected to sample bend testing. |
