We were approached by Altrek Drilling (Calgary) to analyze and make any necessary modifications to the cabins of two Morrooka utility carriers. The equipment needed to meet the requirements of Canadian ROPS standards.
We provided Altrek Drilling with an overview of the work we would be doing and an estimate of our fee, including the possibility of major modifications to the structures. They signed the contract, and we began work immediately.
We worked remotely via phone and email; the information we needed on the structures in question was transmitted by photo. We generated a 3D model in SolidWorks, and the actual measurements were confirmed afterwards.
The model of the original cabin was examined by computer using finite element analysis (FEA) software, to see if the existing structure met the ROPS standard requirements. After verification, modifications were suggested.
We recommended that Altrek Drilling choose the low-cost option: to modify the existing structures with additional reinforcements, rather than rebuilding a completely new cabin structure or adding another roll cage.
The reinforcements were designed and their positioning calculated in parallel with the FEA analysis. The engineering drawings for the modifications and the analysis report were sent to Altrek Drilling for manufacturing on their premises in Calgary.
The project took around one month, from the beginning through to the analysis and final modifications. The results were summarized in a report confirming that the two vehicles were in full compliance with the Canadian ROPS standard.
