Pre Stresser

Pre Stresser

 

Description

The principle of the Pre-Stresser is to support the rim and put a load on the hub area. This way the spokes on one side of the wheel will be stretched and on the other side released.

It Pre Stresser can pick up any wheel from 20”- 29” and is equipped with a wheel database whereby force and displacement for each individual wheel can be stored. 

This process results in a more equal tension over of the spokes, whereby the robot has a quicker run time to true the wheel.
