blocstop™ BSO – material handling
The blocstop™ system, well known from manriding applications, is also used as load arrester to secure loads during material lifting.
Our blocstop™ BSO is small, light and compact and attached to the load where the safety rope runs through it.
If the movement of the safety rope exceeds a specified speed then the BSO triggers automatically and securely catches the load. The safety rope is held between the clamping jaws, preventing the rope from slipping any further. However, the surface of the clamping jaws is large enough to prevent damage to the rope. The blocstop™ is designed in such a way that the clamping jaws grip tighter, the higher the load on the rope.
Furthermore, the blocstop™ has been tested using many times the nominal load in order to ensure an extremely large safety margin.
The blocstop™ BSO includes the following models:
- Without marking: standard version
- E version: with limit switch and 2 metre cable equipped with a plug for the tirak™ connection.
- EFA version: with the option to activate the BSO remotely.
