Periodic Inspection

<Main causes of crawler damage>

Traveling/moving along steps or ridges

Traveling over bridge.

Traveling on roads with sharp bumps (steel bar,
stone etc.).
[Other precautions]

Operating temperature -20
℃
~55
℃
.

Chemicals, oil and salt in sea water may damage the track.

It is prohibited to climb up steps or cross deep ditches directly. Any steps or deep ditches should be leveled with
soil or wood.

It is prohibited to drive obliquely on a slope to prevent accidents caused by the crawler running off the rails.

It is prohibited to turn abruptly during traveling at a high speed. Otherwise, the crawler may fall off the rails and
cause accident.

It is prohibited to travel on roads in a long distance. Use a truck or other vehicles for long-distance traveling.

It is prohibited to use any ramp boards without anti-skid measures.

Check the crawler tension on a regular basis for timely adjustment. Otherwise, wear of the driving sprocket and
iron core of the track may be early.

Check the wear condition of driving sprocket, idler wheel and track roller, and replace when necessary to
prevent damage and crack of the crawler.

Try to avoid crossing the ridge or ditch during field operation, so as to prevent damage and crack of the crawler.

Timely remove the mud, straw and other foreign matters stuck in the crawler if any. Otherwise, the traveling
resistance may be increased.

Reducing the power may lead to crawler crack, inner side scratch and early wear of the driving sprocket.

The track must be correctly tensioned. It may run off the rails if it is tensioned too loosely, or break if tensioned
too tight. In case of abnormal wear of the driving sprocket, the crawler core may be drawn out and lead to
crawler damage, as shown below.
[Note]
The driving sprocket should be replaced if the dimension measured by the calipers shown above is <20mm.
