OSL30 Series Overspeed Safety Lock

An additional safety system in accordance with EN 1808 is mandatory in man riding applications. The system is used to secure the work basket or platform against falling. That is precisely what our high quality OSL30 Series Overspeed Safety Lock does. They are small, light and compact and attached to the working platform where the safety rope runs through it.

If the movement of the safety rope exceeds 30m/min (0.5m/s), then the OSL30 Series Overspeed Safety Lock triggers automatically and securely catches the load. The integrated clamping jaw mechanism made of hardened steel stops the lowering of the wire rope within a few centimetres. Meanwhile, the surface of the clamping jaws is large enough to prevent damage to the rope. Rigid OSL30 Series Overspeed Safety Lock is designed in such a way that the clamping jaws grip tighter, the higher the load on the rope.

Furthermore, the OSL30 Series Overspeed Safety Lock has been tested using many times the nominal load in order to ensure an extremely large safety margin. It is designed for single suspension work cages or platforms with L stirrups.
