For man riding applications a protective secondary safety device is mandatory. For this use Tractel offers the BSO Blocstop™ products. In response to the most strict safety regulations, it 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 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.

Max. load 500 kg up to 3.000 kg.
Automatic clamping of the wire rope by overspeed detection.
