Inspection of the track tightness and adjustment
The tightness of the track is inspected and adjusted with the access platform raised on the
outriggers. The tracks must be inspected for the first time and adjusted, if necessary, after one
hour of use. After this initial inspection, the tracks should be checked and adjusted once a week.
At the same time, the sprocket bolts and nuts should be inspected to ensure that they have not
loosened. Take steps to keep the tracks appropriately tight. This has direct impact on wear and
tear of the track chassis and helps to ensure that the tracks do not come off the sprockets.
To inspect the tightness of the tracks:
-
Raise the access platform off the ground using the outriggers.
-
Drive the tracks back and forth slightly. Check that the tracks are tight:
o
Method 1:
Check the gap between the track and the support skid, see Section
1 in the picture above. The distance should be between 10 and 30 mm. If the
gap exceeds 30 mm, tighten the tracks.
o
Method 2:
Check to make sure that the front-end plate 4 of the track chassis
tightener can move freely. The end plate is located at the front of the track
chassis behind the front sprocket. If the plate moves freely, the adjustment is
correct. If the plate does not move easily, the track must be tightened.
Adjustment of the tightness of the track
Adjustment of the track:
-
The adjustment of the tightness of the track begins with the loosening of locking
screw 2.
-
After this, tighten the tracks using tightening screw 3 until the gap between the pulley
and the track is about 10 mm or until front end plate 4 feels loose.
-
Finally, tighten locking screw 2. The key gap between the tightening and locking
screw is 36 mm.
-
The nut in the end plate must not be adjusted in connection with the tightening of the
track.
