Allira was contracted to design a system for accurate torque bolting of a Rock Crushing Mill built in China.
The system had to be built as a turn-key system to be delivered directly from China to Karratha, Western Australia.

Allira sourced and supplied hydraulic equipment to torque the bolts to an accuracy of 3%.
Using a custom built systeam of hydraulic tooling and pumps, as well as ultrasonics, we were able to set up a system using the ultrasonics to test the kN stretch load on the bolt, and automatically shut off the pump once the bolts had reached the required elongation.
