Alert 00 – 06 Proper Use of Cotter Pins
WHAT HAPPENED:
The anchor pin on the bottom side of the rig’s brake band fell out due to a cotter pin that had been reused. The linkage fell into the upper linkage, which remained attached. The crown saver was activated; however, the linkage bound up under the lock nut and would not allow full application of the remaining brake band. The blocks fell to the ground, out of control. There were no injuries and only minor equipment damage resulting from this incident.
