2-15 PRECAUTION ON USE OF RUBBER TRACK SHOE

The rubber track shoe may be damaged or worn faster depending on working
conditions. Perform working operation properly according to working site conditions
and machine operation.
Structure of Rubber track Shoe
The right illustrates the structure of rubber
track shoe. It consists of steel cord to
sustain tension, iron core to support it, and
covering rubber to them.
CAUTION
If a crack reaches the steel cord, of may
be rusted and cut off by moisture.
When any crack is detected, repair it
immediately with vulcanizer.
Precaution on Use
1. Adjust the track often enough to keep
a proper tension.
• Insufficient tension slips off the rubber
track shoe and wears out the sprocket
and iron core extremely.
• Excessive tension increases travel
resistance, which prevents proper
travel force and speed. it also causes
damages and extreme wear at
u n d e r c a r r i a g e
overextension of the rubber track
shoe.
2. To prevent damages of the rubber
track shoe, avoid the following in travel
