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.
CAUTION
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.
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.
CAUTION
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
undercarriage as well as overextension
of the rubber track shoe.
2. To prevent damages of the rubber track
shoe, avoid the following in travel as
much as possible.
• Pointed rocks or quarry
• Craggy place such as riverbed or path
through woods
• Steel rods or scraps
• Steel board or cornered objects of
concrete
• Heat source such as acre
• Travel in contact with concrete path or
wall
3. Immediately wipe off spilt fuel, hydraulic
oil, or grease on the rubber track shoe
with a cloth.
4. Avoid sudden spot turns or pivot turns.
Make slow turns several times at a low
speed.
5. Do not use for long (3 months or more).
Store it to avoid direct sunlight or rain.
6. Use the rubber track shoe at a
temperature between –25ºC and +55ºC
(–13ºF and 131ºF) because of a rubber’s
characteristic.
