Inquiry about Operator cabin for road roller

We are a company in the construction machinery manufacturing field and are looking for a reliable OEM supplier for complete operator cabins for road rollers. We need a partner to design and supply cabins according to our project requirements. First, please provide a preliminary cabin layout and mounting proposal based on our chassis design, including overall dimensions, mounting points, fixing locations, required modifications for installation, and a general arrangement drawing (2D or 3D CAD if available). After approval of the layout, we plan to purchase one complete cabin prototype for installation, testing, and final approval. The cabin should be supplied as a complete assembly with all related components such as the frame, doors, windows, and safety features.
