Blocstop™ fall arrest device

For man riding applications a protective secondary safety device is mandatory. For this use Tractel offers the BSO and BSA Blocstop™ products. In response to the most strict safety regulations, they can easily be attached to most fittings. The «Tirfor®» jaw-type unit fitted inside the Blocstop™ closes onto the safety wire rope and as the jaws grip over a large area causes no damage to the wire rope.

The BSA models use two ropes, a load wire rope and a safety wire rope. The BSA Blocstop™ remains free on the safety wire rope as long as the BSA-lever is supported in its open position by the load carrying wire rope. A broken load wire rope will instantly result in closing the jaws in the BSA Blocstop™ and the load is safely arrested.
Type "BSA" :

Max. load 500 to 3200 kg.
Operates automatically when there is slack wire rope or an inclined platform.

The BSO models are installed on the platform and move along a safety wire rope. Internal rollers detect the speed of the wire rope passing and instantly close the jaws around the safety wire rope when the speed exceeds a certain set safety limit, thus safely arresting the load.
Type "BSO" :

Max load 500 to 3000 kg.
Automatic clamping of the wire rope by overspeed detection.
