SECTION 5 - OPERATION OF THE SPRING TENSIONER

– Mount and Spring Tensioner Arrangement
5.1 Description
The Spring Tensioner on the IPS differs from previous models in the following areas:

The tensioner is not rigidly attached to the slide bracket. The adjusting screw simply
pushes against the base of the spring jacking plate

Spring height indicator removed

Two slide rods are used to control the vertical movement of the slide bracket
The Spring Tensioner consists of a central threaded adjuster screw (jacking bolt), a spring
jacking plate, two compression springs, nut and locknut. The adjusting screw pushes against
the spring jacking plate to adjust the cleaner mainframe and blade assembly against the belt.
The end of the adjusting screw locates in a recess in the centre of the spring jacking plate.
The springs allow storage of force to take up blade wear, and to absorb belt irregularities or
impact from splices.
The amount of force required to be applied is dependent on the belt width, and is gauged by
the amount of spring compression. The reduction in spring length multiplied by the spring rate
will equal the force applied. Because the spring rate and free length are known, the easiest
measure is of the amount of spring compression after adjustment, and this is easily read by
using a ruler on either side of the slide bracket, measuring between the top face of the spring
jacking plate and the underside of the slide bracket.
