So, what exactly is the MotoSuiveur……?
At its core, the MotoSuiveur (or motor follower) is a load arrest device designed to enhance safety and operational integrity in high-risk environments, particularly within the nuclear and defence sectors, where safety is paramount and risk reduction is non-negotiable.
At the heart of the MotoSuiveur is a deceptively simple mechanical principle. The system is built around a worm and wheel mechanism, which is inherently non-back-drivable, meaning the wheel cannot force the worm to rotate.
This characteristic forms the foundation of the MotoSuiveur’s ability to stop a falling load.
During normal operation, the worm simply follows the movement of the barrel as the load travels. But if abnormal movement or sudden acceleration occurs, the system reacts instantly. The mechanism locks and the worm slides into a damping chamber, safely absorbing and dissipating the energy of the falling load. Instead of transferring dangerous shock forces back into the crane structure, the MotoSuiveur delivers a controlled, damped arrest, protecting both the equipment and the people working around it.
The MotoSuiveur stands out due to its innovative fit and forget design, which integrates traditional engineering principles in an innovative and patented safety solution. This failsafe device not only mitigates risks but also simplifies design solutions when addressing complex safety case issues, making it a gamechanger for teams where safety and secure load handling are critical.

The Importance Of the MotoSuiveur for Industry Professionals
By incorporating the MotoSuiveur into their operational capability, industry professionals can ensure compliance with stringent safety standards while significantly improving operational efficiency and reliability.
The MotoSuiveur is designed to arrest the load within 30° of drum rotation, providing rapid response in the event of a hoist mechanism failure. This ensures immediate load control and protection against mechanical failures within the hoisting system with the exception of the rope itself.
Engineered for reliability, the MotoSuiveur is protected through both robust mechanical design and advanced firmware controls, ensuring dependable performance even in the most demanding environments. With a range of eight units available, offering braking torque capacities from 1,600 Nm up to 102,000 Nm, the MotoSuiveur provides scalable protection across a wide range of crane and hoist applications.
In high-stakes engineering environments where safety, reliability and operational continuity are paramount, the MotoSuiveur is not simply an upgrade, it is an essential safeguard that enhances both compliance and operational confidence.
