TICO Tractors

TICO Tractors, North America's largest terminal tractor fleet owner, needed to replace paper-based quality inspections and handwritten defect logs that were slow, impossible to trend, and relied on manual interpretation of a single physical sheet. As production scaled, this approach became unsustainable.

Deployed Tulip apps on mobile tablets to guide quality inspectors through standardized inspection checklists with defect logging via standardized codes, voice-to-text descriptions, and photo capture. Integrated barcode readers and IoT devices including Andon lights and ZeroKey 3D location tracking for bolt torque sequencing. Built a composable MES for full production tracking.

Reduced quality inspection and rework time by 50–60%. Achieved full production traceability with centralized data accessible to all stakeholders. Eliminated paper-based quality logs and enabled data-driven Pareto analysis of recurring defects. Integrated ZeroKey for 1.5mm-accuracy bolt torque traceability.

Terminal tractor assembly demonstrates how Tulip's composable MES can grow from simple digital work instructions to a full production management system app by app. The ZeroKey integration for bolt sequencing shows the platform's extensibility with novel IoT hardware.
