Inherently Safe Hoisting with MotoSuiveur®
What is MotoSuiveur®
MotoSuiveur Solutions are composed of a MotoSuiveur Unit, its control cabinet and add-on systems. They are configured to the requirements of the hoist. The MotoSuiveur Unit inherently provides fail-safety to the hoist should fault conditions occur. During normal hoist operation and for load recovery, it is controlled by a dedicated Control Cabinet.
| MotoSuiveur Unit Series | Maximal Arrest Torque | Speed at Drum Shaft |
|---|---|---|
| MS0F | 2,400 Nm | Up to 80 rpm |
| MS1F | 6,100 Nm | |
| MS2F | 12,600 Nm | |
| MS3F | 23,000 Nm | |
| MS4F | 40,000 Nm | |
| MS5F | 63,600 Nm | |
| MS6F | 130,200 Nm | |
| MS7F | 225,000 Nm |
Why MotoSuiveur
0ms
response
0%
integrity
0x
shorter arrest than emergency brakes
Load drop/slippage risks eliminated
0s response time, 20mm arrest distance, 100% reliability.
Overspeed risk eliminated
Overspeed is now physically impossible.
Dynamic/static overloads eliminated
Extend your drive chain life, save on maintenance costs.
Load recovery built-in
Your redundant drive chain when the main one fails.
Light integration
Minimal adjustments, outsized safety returns.
Compliance accelerated
No safety-related electronics. No SIL/PL calculations.
Risk elimination
Installing MotoSuiveur® introduces INHERENT SAFETY by POSITIVE MECHANICAL ACTION at the hoist's drum. This is the only way to eliminate - not manage - risks.
- Mechanical Rupture
- Control/Power Failure

Shri Raam Engineering is the exclusive channel partner of SIGUREN Technologies in India, bringing one of the world's most advanced inherently safe hoisting technologies to Indian industries.
We provide complete engineering, supply, installation, integration, testing and commissioning of MotoSuiveur® systems for both new and existing EOT and gantry cranes. Our experienced engineering and site execution teams ensure seamless retrofit of the system with minimal modifications to the existing crane while maintaining the highest standards of safety and reliability.
Engineered for Existing Cranes
One of the greatest advantages of MotoSuiveur® is its ability to be integrated into existing cranes from virtually any manufacturer.
Whether your crane has been operating for 10 years or 40 years, SRE engineers evaluate the complete hoisting mechanism and develop a retrofit solution that integrates MotoSuiveur® with minimal disruption to the existing crane arrangement. The system is designed for both new installations and modernisation of legacy cranes, making it a practical solution for industries seeking higher safety without replacing their entire crane.
