Introduction
Weld East Fabricators was engaged to adapt a left-hand platform from a 930E Komatsu mining truck for fitment onto a Caterpillar truck. The challenge was significant: the platform was not originally designed for the Caterpillar, which meant new mounting arrangements had to be developed from scratch. At the same time, all existing safety devices – including lights – had to be retained in their original positions. The project required a careful combination of site measurement, 3D scanning, CAD modelling, and detailed fabrication documentation to deliver a functional, safe, and compliant result.
Project Focus and Challenges
Adapting a large-scale mining truck platform from one OEM to another is not a straightforward task. The mounting points, structural geometry, and accessory positions differ between manufacturers, meaning every dimension had to be verified against both machines before any fabrication work could begin.
Our team conducted a site visit to carry out a full survey of the existing left-hand platform, capturing detailed measurements across its entire structure. A 3D scan of the Komatsu platform was also completed, providing a precise digital record of the original geometry. This scan was processed and imported into SolidWorks, where a full 3D model was developed. The Komatsu platform model was then compared directly against the Caterpillar truck measurements in 3D, allowing our engineers to identify and resolve fitment conflicts before committing to any drawings.
With the 3D comparison complete, detailed 2D fabrication drawings were produced. These drawings gave our fabricators clear instructions for cutting, pressing, and welding each section and bracket to the required specifications. The retention of the original safety device positions, including lighting, was incorporated into the design at this stage, ensuring compliance with the client’s site safety requirements.
The site visit and full platform survey added time to the project. Ordered in early September 2024, the platform was delivered in mid-November 2024 – a turnaround that reflected the scope of work involved, particularly given the complexity of capturing an entire large-format platform in the field.
Project Outcomes
The completed platform was fabricated to fit the Caterpillar truck whilst preserving all original safety device positions from the Komatsu unit. The client received a purpose-built solution that addressed the cross-platform mounting requirements without compromising on safety or structural integrity.
This project demonstrates our ability to solve complex, large-scale prototyping challenges through a structured process – from site measurement and 3D scanning through to SolidWorks modelling, 2D drawing development, and final fabrication. It highlights the value of having design, engineering, and fabrication capabilities under one roof, with the flexibility to work directly on site when the job demands it.
For mining operations managing mixed fleets, the ability to adapt components across machine types can reduce lead times and costs compared to sourcing new OEM parts. Our repair and refurbishment services and general fabrication capabilities are well-suited to these types of cross-platform challenges.
Projects like this one reinforce what we have been doing since 1982: taking on technically demanding fabrication work and delivering practical solutions that keep equipment operational. Whether the requirement involves a standard component or a one-off prototype at scale, our team has the skills and equipment to work through it methodically from start to finish.
