Faults in the lifting column
If any mechanical faults or misalignments occur
in the lifting column and/or runner-block/lifting-
arm, no attempt must be made to repair them.
Structural damage to these parts can impair the
lifting strength, and therefore the parts must be
returned to the manufacturer for assessment and
repair as necessary. Contact Molift Group AS.
