When replacing the ring rails on BHP’s Car Dumpers we provided services that removed the existing worn rails, installed the replacements using ultrasonic bolt elongation measurement to control the critical bolt tension. Notable successes from this process were: -
-
100% of the bolts removed using engineered special tools without the need for any gas cutting
-
This saved BHP more than 24 hours compared with previous methods
-
Re-assembly using the same special tools but controlled with ultrasonics saved another 24 hours
-
The speed and accuracy of ultrasonic monitoring ensured no bolt failures during operation
-
Our special torque tooling machines went through over 8000 cycles with zero failures
-
Our 24 technicians had zero incidents or accidents
