BELT TENSION
The tension on the belt should be adjusted as shown in Fig-
ure 20.
FIGURE 20 : BELT ADJUSTMENT
Procedure for adjusting belt tension:
1. Loosen six nuts (top and bottom) A.
2. Adjust by turning (B).
3. Never loosen nuts (C).
4. Use belt tension checker to apply a perpendicular
force to one belt at the midpoint of the span as shown.
Deflection distance of 4mm (5/32”) is obtained.
To determine the deflection distance from normal
position, use a straight edge from sheave to
sheave as reference line. The recommended
deflection force is as follows:
Tension new belts at the max. deflection force rec-
ommended for the belt section. Check the belt
tension at least two times during the first 24 hours
of operation. Any retensioning should fall between
the min. and max. deflection force values.
5. After adjusting retighten nuts (A).
