Autoquip SPIRALIFT SCISSORS LIFT - Manual (Page 27)

27
One of the driving belts on the
drive unit is broken. • If at any time one of the driving belts breaks
loose, the platform movement will stop
automatically. A proximity switch senses the
broken belt and the platform will not move until
this belt is replaced. Block the platform in its
position. Remove the load. Verify that the
platform won’t move. Remove the belt guard
and replace both belts. If the column has been
lowered away from the top platform, re-insert
the top plate of the column into its pocket
according to previous steps described.
PROBLEM POSSIBLE CAUSE AND SOLUTION
Platform jams during downward
stroke. Stop the lift immediately if
it has not already stopped
automatically (continued from
previous page). • The column has lost its integrity (i.e., the
vertical band has come out of the grove in the
horizontal band.) Block the platform in its
position. Remove the load. Feed the two
bands back into their respective storage
position by rotating the head of the column. If
this is difficult, remove the retaining screws at
the top end of the vertical band and then feed
the two bands back down individually. When
the horizontal band and the head assembly are
at the bottom and the vertical band is in the
magazine, re-attach the vertical band to the
head assembly and reinsert the retaining
screws. Rotate the column assembly up, by
hand, by rotating the top plate slowly. Proceed
with the corrective measures described above.
