Monorail Design Checks and Certification

Keeping monorails in good working order is key to keep production uninterrupted

Monorails are extensively used in industry to assist with the transportation of equipment. As it is a vital piece of infrastructure it needs to be maintained and inspected frequently. Dynamic Engineering Consultants can assist with your monorail inspections, design checks and certifications. Below are some examples where we assisted our clients with their monorails:

Corrosion inspection

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. We were 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.

Reduction of sway movement

Our client was concerned about the horizontal sway movement of the supporting steelwork of an existing monorail beam. This sway movement occurred mainly when a load was moved along the monorail beam. Dynamic Engineering performed monorail design checks. After analyzing the structure, we advised our client that the supporting structure had to stiffened and upgraded in order to reduce the above-mentioned sway. The frame was modified and a significant improvement was noted. The result was another satisfied client.
