Reduction in CAB Costs

A heavy machinery manufacturer of off-road construction, mining, and paving machines approached ARi to update an existing CAB (operator station).

Project Scope

A heavy machinery manufacturer of off-road construction, mining, and paving machines approached ARi to update an existing CAB (operator station).


Business Challenges

New CAB design needed to reduce the current manufacturing costs, overcome existing stress problems, and update to current technology, all without effecting form, fit, and function.


ARi’s Solutions


  • Identified parts that can be integrated resulting in part count reduction and weight reduction.

  • Identified and Localized the CAB parts (HVAC cover plate, Transmission control cover) from being an export item.

  • Validated the design through pugh matrix.

  • Design upgraded and commonized the CAB with other existing models.

    • Design upgrades included and not limited to:

      • Replaced Long Piano Hinges with 3 small hinges.

      • Zipped Glass replaced Instead of Bonded Window.

      • Trainer Seat assembly – replaced magnet assembly with Lock seal mechanism.

      • Commonized the simple weld links in all the areas of CAB.

      • Changed the mountings of controls (Chassis and Brake ECM).

      • Updated the Design of Panel and Dash to accommodate the 6G cluster and advisor.

      • Updated the Panel Design to accommodate the A4-M1 ECMS.






ARi’s Value Proposition

Through our focus on high quality, low-cost development, we reduced the overall cost of the CAB by 5%. Also, reduced the BOM count for the CAB and commonized the parts, resulting in cost reduction with a reduced inventory.
