Explore our flagship heavy-duty industrial electric motors, gearboxes, and speed reduction systems engineered to withstand severe shock loads, sub-zero Arctic temperatures, and continuous 24/7 duty cycles.
As Sweden accelerates its transition toward green heavy industry, fossil-free steel manufacturing, and automated underground mining, the demand for ultra-reliable, high-torque heavy duty gearboxes and industrial motor drives has reached an unprecedented peak. Operating machinery in Northern Sweden (Norrland), Kiruna, and the industrial centers around Gothenburg and Stockholm requires power transmission components built specifically to endure extreme mechanical shock loads, high radial forces, and sub-zero Arctic ambient conditions.
T-T Electric, drawing upon over 120 years of manufacturing excellence, engineered modular industrial electric motors, square-frame AC variable speed units, heavy-duty DC motors, and companion heavy duty gearboxes engineered to match the rigorous demands of Swedish OEM engineers, system integrators, and industrial plant managers. Every gearbox unit exported to Sweden complies fully with European Union Eco-design Directives (EU 2019/1781) and relevant SS-EN ISO quality standards.
Selecting a heavy duty gearbox for Swedish industrial applications demands a precise evaluation of mechanical, thermal, and environmental parameters. Miscalculating thermal dissipation limits or service factors in unheated paper mills or exposed mining crushers can lead to premature gear tooth pitting, shaft fatigue, or seal degradation.
From underground iron ore extraction in Norrbotten to coastal maritime shipping hubs in Gothenburg, our heavy duty gearboxes and motor drive packages power Sweden's primary industrial sectors.
Heavy duty planetary and helical bevel gearboxes installed on underground jaw crushers, slusher hoists, and continuous ore conveyors. Engineered with dust-tight IP66 enclosures and reinforced housings to withstand relentless vibration and rock impacts in subterranean iron ore mines.
High-torque heavy duty speed reducers paired with T-T Electric laminated frame DC and square-frame AC motors powering steel roll tables, hot strip mills, and heavy wire drawing machines. Capable of handling 300% intermittent overload torques during ingot reversing cycles.
Parallel shaft helical gearboxes driving heavy log debarkers, chippers, and paper machine dryer rolls. Outfitted with high thermal capacity housings and continuous oil filtration loops to prevent wood flour contamination and thermal breakdown.
Custom speed-increasing gearboxes for small-to-medium hydroelectric dams and river turbine installations across Sweden. Features ultra-high efficiency gearing (up to 98.5% per stage) to maximize electrical megawatt output into the Swedish national grid (Svenska kraftnät).
Corrosion-resistant marine-grade heavy duty gear drives built for ship-to-shore gantry cranes, heavy container stackers, and ship mooring winches. Treated with multi-layer epoxy marine coatings resistant to Baltic sea saltwater spray.
Compact heavy-duty brushless DC gearboxes integrated into automated heavy-payload transport platforms used in modern Swedish smart factories and warehouse distribution centers, operating efficiently at 24V/48V battery voltage levels.

Sweden has established one of the world's most aggressive decarbonization targets: achieving zero net greenhouse gas emissions by 2045. Key industrial pillars—including green steel ventures (HYBRIT and H2 Green Steel), mining giant LKAB's electric transition, and sustainable forestry leaders like Stora Enso and SCA—are replacing fossil-fueled hydraulic drives with high-torque electric motor and heavy duty gearbox combinations. Our high-efficiency drive packages directly support this green transformation by reducing electrical grid losses by up to 4.5% compared to legacy gear systems.
In sub-arctic Sweden, machinery operates under extreme ambient conditions where winter temperatures frequently plummet below -30°C. Heavy duty gearboxes operating in unheated enclosures must overcome dual challenges: avoiding brittle fracture of gear housings during cold startup, and maintaining structural oil film strength when internal temperatures reach +80°C under full continuous load. T-T Electric gear solutions for Sweden incorporate ductile iron housing materials (EN-GJS-400-18-LT), integrated low-wattage immersion oil heaters, and double-lip fluoropolymer seals to guarantee instant start-up without seal tearing or gear scuffing.
Swedish industrial procurement protocols demand strict adherence to European norms (CE mark, Machinery Directive 2006/42/EC, ISO 9001 quality management). Every heavy duty motor and gearbox delivered by T-T Electric is registered in our centralized manufacturing tracking database. By simply referencing the unit's unique serial number, Swedish maintenance crews can instantly retrieve complete dimensional blueprints, original gear tooth cutting tolerances, bearing part numbers, and exact spare part replacement bills of materials (BOM), eliminating expensive mill downtime.
With an engineering legacy exceeding 120 years, T-T Electric stands among Europe's most established pioneers in rotating machines and heavy power transmission. Our manufacturing plant in Persan, France, operates under rigorous LRQA ISO 9001 certification and maintains active memberships in prestigious international organizations including EASA (Electrical Apparatus Service Association) and AEMT (Association of Electrical and Mechanical Trades).
