Retrofit kit adding autonomous capability to existing excavators and loaders via LiDAR, cameras, GNSS, and hydraulic sensors.
Gravis RACK is a sensor and software retrofit system that converts standard earthmoving equipment into autonomous or semi-autonomous machines for trenching, grading, and stockpile management. It addresses labor scarcity and on-site safety by eliminating operator exposure to hazardous conditions and enabling continuous operation. The system uses multi-modal perception (LiDAR, RGB, GNSS) and hydraulic feedback to autonomously execute preprogrammed or real-time soil-moving tasks without full fleet replacement.
Gravis RACK converts excavators and loaders already on site into semi-autonomous or fully autonomous earthmovers via a sensor-and-software retrofit — LiDAR, cameras, GNSS, and hydraulic feedback doing the work that operators would otherwise perform in dust, heat, and hazardous proximity to active works. The labour-scarcity and safety case is genuine, and the proposition to retrofit rather than replace existing capital is commercially astute. Evidence sits at inndex 62 with a single provided data point, which means the performance claims — 30% productivity gain and 97% bucket fill accuracy — come from the vendor or a narrow pilot rather than independent multi-site validation; the deployment data on long-term reliability and failure modes in varied conditions does not yet exist. The immediate risk a specifier should weigh is not technical but regulatory: liability frameworks for autonomous heavy equipment on mixed-use construction sites are unresolved in most jurisdictions, and insurers have not kept pace with the technology. Operationally, the retrofit demands pre-site GNSS survey and digital job planning, which means it is suited to earthworks programmes with predictable, well-defined scopes rather than ad-hoc or rapidly evolving work faces; ill-defined terrain or frequent scope change resets the efficiency maths. Worth watching on infrastructure and civil projects where earthmoving is high-volume and site conditions are stable, but the regulatory and reliability evidence gap means early adoption carries programme-contingency cost that must be budgeted explicitly.
Company website and schema.org confirm founding (2022), location (Zurich), and core product (RACK retrofit kit). Taylor Woodrow Manchester Airport deployment cited as 'first large-scale autonomous excavation on active site' in UK—no independent third-party audit found; claim relies on company narrative. Series A round ($23M, late 2025, IQ Capital + Zacua + Holcim strategic) is plausible but unverified via venture databases at submission. Performance metrics (30% productivity uplift, 97% bucket fill) lack published methodology, control groups, or peer review—typical vendor claims, not independently validated. OEM partnerships (Hitachi, Develon) at CONEXPO 2026 are forward-looking (trade show demonstrations), not evidence of production integration. No safety certifications, regulatory approvals, or liability frameworks documented in accessible sources.
