What SIGUREN technologies does

SIGUREN technologies Ltd. is a privately held UK-incorporated industrial safety company (operational headquarters in Paris, France; secondary presence in Plovdiv, Bulgaria) that designs, manufactures, and sells MotoSuiveur®, a passive mechanical safety system for high-duty industrial cranes and hoists. The technology achieves inherent safety through positive mechanical action at the hoist drum, requiring no power, sensors, encoders, or safety PLCs to function; its stated performance metrics include 0ms response time, 20mm arrest distance, and 100% safety reliability. The product portfolio spans the MSF passive friction line (MS0F–MS7F) and the MSH hydraulic damping line (MS0H–MS7H) for capacities up to 150 tonnes, supplemented by a six-model torque limiter family (MS-TL50–MS-TL160) and three load recovery tools (MS-IRD remote drive, MS-HRT handheld, MS-PRT portable) that address overload, two-blocking, and post-event recovery scenarios.

The company targets enterprise customers in safety-critical industries where load-drop or overspeed events carry catastrophic financial, environmental, or human consequences. Its disclosed reference base of 24+ customers spans nuclear (Sellafield Ltd, CEA, Urenco, EDF, European Spallation Source, ONDRAF, AWE), steel and metals (Ternium, Vallourec, Aurubis, Bulgarian copper smelter), aerospace (Rolls-Royce), defense (BAE Systems, UK defense contractor at 150t, UK defense shipyard at 125t), and heavy manufacturing/logistics (truck trailer, concert hall lorry elevator). Deployments span nine countries across Europe, Latin America, and Asia-Pacific, with product use cases ranging from 4t nuclear waste retrieval cranes to 150t defense nuclear material handling.

SIGUREN generates revenue through direct enterprise sales of hardware units and add-on modules, with all transactions routed through a consultative 'Request a hoist assessment' process that yields custom quotes and typically multi-year contract terms. The GTM is direct field sales only — no distributors or resellers are disclosed — and pricing varies by product model, capacity, and application complexity. Ownership is founder- or privately-held, with no external institutional investors, funding rounds, or M&A activity disclosed in the source material.

Core offering

SIGUREN technologies designs, manufactures, and sells the MotoSuiveur® line of passive mechanical safety systems for industrial cranes and hoists. The technology provides inherent load-drop, overspeed, and overload protection through positive mechanical action at the hoist drum, requiring no power, sensors, encoders, or safety PLCs to function. Products are sold as retrofit upgrades or as part of new hoist installations across nuclear, steel, aerospace, and defense industries.

Product overview

SIGUREN technologies offers the MotoSuiveur® line of inherent safety solutions for industrial hoists. The portfolio consists of two core product lines: Passive Friction MotoSuiveur® (MSF) units (MS0F through MS7F) providing mechanical load arrest through positive friction action, and Hydraulic Damping MotoSuiveur® (MSH) units (MS0H through MS7H) designed for heavy industrial and nuclear applications with integrated recovery capabilities. Both lines are supplemented by Torque Limiter add-ons (MS-TL50 through MS-TL160) that prevent overload and two-blocking, and Load Recovery add-ons (MS-HRT Handheld Recovery Tool, MS-IRD Integrated Remote Recovery Drive, and MS-PRT Portable Recovery Tool) enabling safe load recovery when primary drive systems fail. The system operates as a retrofit solution installable on any hoist manufacturer or configuration, providing 100% reliability with 0ms response time and 20mm arrest distance.
