technogrid® CONVEYOR TENSION TAKE-UP COUNTER- WEIGHT ARRESTING

One of the newest applications of the Technogrid® is the arresting of the conveyor counter weights. In some applications, if the belt snaps and the counter weight falls to the ground, there is no damage done and it is not an issue. In other cases, however, if the counter weight falls and does serious damage to structures or equipment below, then counter weight arresting needs to be considered.

The Technogrid® provides the ideal solution to this problem. The specified Technogrids are simply 'hung up' vertically next to or below the counter weights with a catch frame attached to the bottom of the Technogrids. The catch frame is situated just below the lowest point of the normal vertical movement allowed for the counter weight. The top of the Technogrids are anchored to the structure. The structure must be verified to ensure that it can handle the impact forces which are generated by the impact (see data sheet for end forces). Upon impact, the Technogrids will stop the counter weight and absorb all the energy and the counter weight will remain on the catch frame until reinstalled on the repaired conveyor belt.

After a full impact, the Technogrids simply need to be replaced and then the Technogrid arresting system is ready for the next impact. The Technogrids available for this application range from 12kJ to 225kJ (see data sheet for options) and can be used in any combination of series or parallel up to 5000kJ.
