Machine will not
rotate load (motor
runs)
Maintenance chains engaged Verify the maintenance chains are not engaged.
Motor may be turning in the wrong
direction (three phase machines)
Check motor rotation direction (counter clockwise as
viewed from the shaft end of the motor). If motor is
rotating the wrong way, swap any two phases.
The load exceeds the maximum capacity Verify load weight does not exceed the rated
capacity. See section 5.2.1. Load Restrictions.
