What Terox does

Terox Group AS is a privately held Norwegian engineering company that develops and manufactures hybrid and fully electric construction equipment for the tunnel and underground infrastructure industry. Its core offering, the Greenline platform, converts proven Caterpillar base machines (C315, C325, C326, C340, C352, M322) into hybrid or fully electric operation using proprietary cable management, motor, and control systems. The portfolio extends beyond excavators to include the X-Lift 1000 work platform, the X-DT15/20/30/35 hydraulic drill tower series (built on Epiroc drilling components), the X-TL2000 fully electric tunnel loader, and supporting infrastructure — the X-CS cable mast, X-CC450 cable container, and Quick Charger 350 kWh charging container.

The company monetises primarily through direct, quotation-based capital equipment sales to enterprise contractors, supported by a 24/7 service and spare-parts operation, machine resale, and increasingly through charging infrastructure and depot charging installations (e.g., the Nulandsvika facility for Connect Bus electric buses). Distribution is handled exclusively by a small, named in-house sales team (Runar Jansen, Morten Holm-Andersen, Inge Senum Liest\u00f8l) without dealer or reseller channels, targeting enterprise customers in Norway and select international markets.

Terox positions itself as a market-leading supplier in the Norwegian hybrid/electric construction-equipment segment, with its growth thesis tied to the country's fossil-free construction-site mandate for public procurement, CO2 taxation on equipment, and a complete-vendor approach spanning machines, power infrastructure, controls, and service. Operations are run from Flekkefjord (manufacturing) and Hauge i Dalane (registered headquarters), with the company taking ownership of its Flekkefjord facility in January 2026.

Partnerships

Two partnerships are on record, tiered minor and core.

• Connect BusminorStrategic or Co-development PartnerConnect Bus operates electric buses that charge at Terox's Nulandsvika charging facility. Terox installed a SEC 360 kW Power Unit with 4 charging poles at the depot. This represents a customer-supplier charging infrastructure relationship, with Terox providing the charging infrastructure and Connect Bus providing the electric bus fleet.
• EpiroccoreTechnology or IntegrationEpiroc supplies key drilling technology components across Terox's entire drill tower product line. Terox uses Epiroc hydraulic drill machines (COP SC19, COP SC25, COP SC14, COP 1028), drill feeds (T35, T30, T20, T15), and associated systems in its X-DT15, X-DT20, X-DT30, and X-DT35 drill towers. This is a deep technology integration partnership where Epiroc's proven drilling systems form a core component of Terox's products.

Scale indicators4 records

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• Caterpillar: Global construction and mining equipment OEM and the source of Terox's base machines (CAT315/325/326/340/352). Comparable because Caterpillar itself is launching electric and hybrid construction machines, which directly overlap with Terox's converted Greenline products.
• Komatsu: Global construction and mining equipment OEM with electric and hybrid product initiatives (e.g., PC30E-5 electric mini excavator, hybrid hydraulic excavators). Comparable as a broad incumbent pursuing similar zero-emission construction equipment strategies.
• Volvo Construction Equipment: Swedish-Nordic OEM of construction equipment (excavators, loaders) with an expanding electric compact and mid-range machine portfolio. Comparable as a Nordic incumbent addressing the same fossil-free mandate with full OEM electric offerings that could compete against Terox's conversions.
• Liebherr: Family-owned OEM of construction machinery (excavators, loaders, drilling rigs) with battery-electric demonstrators and select production electric models. Comparable as a broad incumbent serving similar tunnel, infrastructure, and mining construction customers.
• JCB: UK-based construction equipment OEM with one of the industry's broadest electric compact machine ranges (19C-1E mini excavator, etc.). Comparable as an incumbent commercialising electric construction equipment that targets many of the same emissions-driven use cases as Terox.

Direct peers

• Epiroc: Swedish manufacturer of underground and surface mining and infrastructure equipment with a growing electric/hybrid portfolio (e.g., battery-electric loaders, drill rigs, and trucks). Most directly comparable peer to Terox given the shared focus on electrifying underground and tunnel equipment, and is also Terox's core drill-technology supplier.
• Normet: Finnish manufacturer of underground equipment (loaders, trucks, shotcrete sprayers) with a clear electric and battery-electric product roadmap for tunnelling and mining. Comparable to Terox because it sells purpose-built electric machines into the same tunnel/underground construction customer base.
• Sandvik Mining and Rock Solutions: Division of Sandvik providing underground drill rigs, loaders, and rock tools with battery-electric variants. Directly comparable to Terox in electrified underground and tunnel equipment, with overlapping customers in the Nordic region.

Emerging players

• MacLean Engineering: Canadian manufacturer of underground mining equipment with a dedicated battery-electric and electrification product line (BV-series). Comparable to Terox as a niche electrification specialist focused on underground and heavy equipment customers.
• Wacker Neuson: German manufacturer of compact construction equipment with a broad zero-emission product line (electric mini excavators, dumpers, wheel loaders). Comparable as a focused competitor in the electric construction-equipment niche, although smaller and more urban/light-duty than Terox's tunnel focus.
