One-Way Tensioners - TENBLOC GdR

High Quality Products

Tecnidea GdR Serie – One-Way Tensioners

The innovative solution to tension conveyors continuously, automatically, one-way (only push).

On the tensioner acts a ratches-gear which does not allow the column to reenter while working. The tensioner automatically takes up any stretching, but at hte same time it operates as a fixed tensioner.

This application is particularly useful for cutting out whiplashes and axial oscillations. The M8 screw on the bottom has the function both to create the uni-directional system and to pre-load the tensioner.
