Blocstop BSO and BSA load arresters can handle, stop and hold material-only loads of up to 3000 kg. The BSO is small, light, and compact, and can be fixed directly above the Tirak hoisting device running and run on the same wire rope or can be fixed on a attachment point with a secondary wire rope. The Blocstop BSO is actuated as soon as the triggering speed is reached. Several speeds are available upon request.
The BSA load arresters use a lever, which will activate the clamps to catch the load if the suspension rope breaks. The Blocmat S or SI model can handle material-only loads of up to a tonne and has an integrated reeler, which can store up to 25m of wire rope. The Blocmat TSD is a mobile load arrester.
