Monorail Design, Checks and Certification

Monorail design checks

Corrosion is part of everyday life in an underground mine and when equipment has been in use for several years, it can become a safety concern. Dynamic Engineering Consultants was requested to determine if an existing corroded monorail beam is still fit for purpose and if not, to specify repairs. Structural analysis (based on Australian Standards AS1418) was done to determine the minimum required thicknesses of the beam to support the hoisted load. The thicknesses were then compared with the actual thickness of the beam to ascertain if the beam was still strong enough and a repair procedure was developed accordingly.

Container monorails

When a shipping container is used to transport heavy items, monorails are sometimes installed inside that can extend outside the container. This is used to lift and move items from inside of the container. Dynamic Engineering was asked to design such a retractable container monorail according to the relevant Australian Standards (AS1418). In addition, the support beams, which connected to the container needed to be strong enough and were included in the design. DEC took the client’s initial concept and turned it into a working model with fabrication drawings. The following picture show the final design.
