The Tractel BLOCSTOP is designed specifically for suspended platforms to automatically arrest a fall though has many other possible applications.

As well as being sound safety management, regulations require you to ensure your equipment for lining personnel or loads is safe.

BLOCSTOP safety systems meet the most exacting safety requirements and can be easily adapted to numerous types of applications.

Blockstop BSA  Technical

Decisive Advantages

  • The TIRFOR type jaw unit fitted in the BLOCSTOP closes on the suspension or secondary wire rope. It grips over a large contact area, causing no damage to the wire rope.
  • Automatic operation of the clamping mechanism.
  • The Blocstop BSA operates automatically when there is slack wire rope , caused either by breaking of the wire rope or there being no load.
  • It provides anti-sloping protection, limiting the incline of the platform to a maximum of 14°.

This type of BLOCSTOP is an automatic slack wire rope safety device which can only be used on a secondary safety wire rope positioned parallel to the suspension wire rope.

When the hoist and BLOCSTOP BSA are mounted on a stirrup which is rigidly connected to the platform, as is generally the case in Europe, the BLOCSTOP BSA not only protects against failure of the hoist and the main wire rope but also against excessive slope of the platform. To ensure operation of this BLOCSTOP BSA, the distance between the upper suspension points has to be 100 mm.
