Tank Cradle Arm Failure

A 1,000-barrel tank was being moved into place when the cradle arm bracket failed. The bracket was held in place by the main mast pin, which was secured with a cotter pin. The cotter pin broke, allowing the main mast pin to slide out of place. As a result, the tank slid off the cradle, fell to the ground, and landed on its side, damaging the tank. No injuries occurred.
